Abstract
Background: The novel coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome
coronavirus-2 (SARS-CoV-2), is the global health concern since December 2019. It has become a big challenge for
the researchers to find a solution for this newly evolved pandemic. In Ayurveda point of view, COVID-19 is a
Janapadodhwamsa vikara (epidemic disease), a situation where the environmentair, water, land, and seasonsis
vitiated, causing a simultaneous manifestation of a disease among large populations. The aim of this study is to
identify the active compounds of selected Ayurveda medicines recommended for COVID-19.
Results: The selected preparations are traditionally recommended for the management of various kinds of fever
including the infectious ones and to enhance the immunity. HPTLC analysis of the same showed presence of many
active molecules like umbelliferone, scopoletin, caffeic acid, ferulic acid, gallic acid, piperine, curcumin, berberine,
and palmatine.
Conclusion: The study provided valuable scientific data regarding the active ingredients of the selected medicines
with proven therapeutic potentials like anti-viral, immunomodulatory, and anti-inflammatory activities.

1 Background
COVID-19 has emerged as the most dangerous global
pandemic threat since its outbreak during December
2019 in Wuhan, China. As of September 4, 2020, the
World Health Organization (WHO) has reported more
than 26 million confirmed cases and 8.6 lakhs deaths
worldwide and it has spread to 216 countries, areas, or
territories (https://www.who.int/emergencies/diseases/
novel-coronavirus-2019). Now, it is a big challenge for
the researchers and health professionals to find out a so-
lution for this deadly viral infection. COVID-19 is a viral
infection that has been known to have the fastest fre-
quency of replication in its positive strand resulting in
the quick development of new progeny viral cells inside
the host cells. SARS-CoV-2 is a single-stranded RNA
pathogen, which is characterized by a high mutation rate
[1,2]. In Ayurveda point of view, COVID-19 is a Jana-
padodhwamsa vikara (epidemic disease), a situation
where the environmentair, water, land, and seasons
is vitiated, causing a simultaneous manifestation of a dis-
ease among large populations [3].
Medicinal plants have been used as a treatment and
defensive strategy for several infectious diseases since
ancient times. The benefit of using these herbs in viral
respiratory infections is to build immune-stimulating
and inflammation-modulating effects to prevent severe
life-threatening conditions. Holistic approach of Ayur-
veda focuses on prevention of diseases through lifestyle
modification, dietary management, prophylactic inter-
ventions for improving the immunity, and managing the
symptoms using herbal preparations. Medicinal plants
have been reported to have anti-viral activity and many
species such as Aegle marmelos,Andrographis panicu-
lata,Acacia nilotica,Ocimum tenuiflorum,Piper nigrum,
Solanum nigrum, and Terminalia chebula have been sci-
entifically proved for their anti-viral properties [46].

Ayurveda medicines were recommended by the Ministry
of AYUSH, Government of India to enhance the immunity
and to prevent the severe conditions of Cov-2 infection.
Detailed guidelines have been published by the AYUSH
Ministry regarding the management of COVID-19 (https://
www.ayush.gov.in/ayush-guidelines.html). About 80% of
COVID-19 cases are with mild symptoms requiring only
primary medical care. Ayurveda medicines are advised to
patients with mild symptoms and those under surveillance
which addresses the therapeuticprovincewithinanintegra-
tive model of care [7]. The present study was focused on
the identification of active ingredients of certain Ayurveda
medicines such as Indukantham Kwatham (IK), Vilvadi
Gulika (VG), and Mukkamukkatuvadi Gulika (MMG) in
which the ingredient plants have been reported to possess
immunomodulatory and anti-viral properties.
Indukantham Kwatham is a polyherbal tablet prepared
out of specific parts of different medicinal plants such as
Holoptelea integrifolia,Cedrus deodara,Gmelina
arborea,Aegle marmelos,Stereospermum colais,Oroxy-
lum indicum,Premna corymbosa,Desmodium gangeti-
cum,Pseudarthria viscida,Solanum anguivi,Solanum

2 Methods
2.1 Chemicals and reagents
Chemicals such as toluene (CN: IE5F650118), ethyl acet-
ate (CN: ID5F650128), and methanol (CN: SA5P650021)
were procured from Merck India.
2.2 Sample preparation
The selected medicines were obtained from the Product
Development Department of the Institute. Two grams
each of IK (Batch No. 198339), VG (Batch No. 193083),
and MMG (Batch No. 194967) were sonicated with
chromatographic grade methanol in an ultra-sound bath
(Labnet Scientific, India) for 20 min. It was then filtered
through a membrane filter (0.45 μm) and kept under the
refrigerator until HPTLC analysis.
2.3 Instruments and general chromatographic conditions
HPTLC analysis was carried out by the CAMAG HPTL
C system (Switzerland). Samples were applied using
CAMAG ATS 4 auto sampler on aluminum backed pre-
coated silica gel 60F
254
HPTLC plate (Merck India).
Mobile phase was optimized as toluene, ethyl acetate,
and methanol in the ratio of 7:3:1. The chromatogram
was developed in a saturated Twin Trough chromato-
graphic chamber (Camag, Switzerland) and was visual-
ized under UV-chamber (254 and 366 nm) and in visible
light after derivatizing with anisaldehyde sulfuric acid re-
agent followed by heating at 105 °C for 5 min.
3 Results
Rapid chromatographic method has been developed for
the chemical fingerprinting of selected medicines by
modern high-performance thin-layer chromatography.
The optimized mobile phase provided good resolution
under various documentation systems such as UV-254,
366, and visible light. Chromatogram and 3D-illustrated
display are presented in Fig. 1. HPTLC analysis showed
presence of various compounds belonging to different
groups of phytochemicals such as alkaloids, coumarins,
and phenolics. Structural identification was confirmed
with matching R
f
of standard compounds. The com-
pounds identified from the tested formulations are given
in Table 1.
Coumarins such as umbelliferone and scopoletin are
detected in all the three selected medicines and these
are the plant coumarins reported from many medicinal
plants. Phenolic compounds like caffeic acid and ferulic
acid are found in both IK and VG. Gallic acid was iden-
tified from all the three selected medicines and has been
reported from many ingredient plants. VG showed the
presence of alkaloids such as curcumin, berberine, and
palmatine which might have extracted from its ingredi-
ent plants like Piper nigrum,Piper longum,Curcuma
longa, and Berberis aristata.
4 Discussion
Bioactive compounds from natural products are attractive
candidates for drug development. Numerous medicinal
plants have been reported to possess various therapeutic
properties including anti-viral, anti-inflammatory, and im-
munomodulatory activities. The chemical profiling of
three selected medicines showed the presence of various
biologically active compounds belonging to different clas-
ses of phytochemicals such as alkaloids, phenolics, and
coumarins. Coumarins such as umbelliferone and scopole-
tin were found to be common for all the selected samples.
Naturally occurring coumarins have been reported to pos-
sess diverse biological and pharmacological properties such
as anti-viral, anti-coagulant, anti-bacterial, anti-fungal, anti-
protozoal, insecticidal, fungicide, anti-mycobacterial, anti-
mutagenic, anti-amnesic, and anti-inflammatory activities
[9,10]. There are numerous evidences for the inhibitory
role of coumarins against infection of various viruses such
as HIV, influenza, enterovirus 71, and coxsackievirus A16.
The mechanisms involve either inhibition of proteins essen-
tial for viral entry, replication, and infection or regulation of

cellular pathways such as Akt-Mtor, NF-κB, and anti-
oxidative pathways including NrF-2 [11].
Alkaloids such as piperine, curcumin, berberine, and
palmatine were identified from the selected medicines.
Piperine is detected from both IK and MMG and that
might have come from the ingredient plant Piper
nigrum. The immunomodulatory potential of piperine
has been reported earlier [12]. Piperine was reported to
inhibit proliferative response induced by lipopolysac-
charide (LPS) and immunoglobulin α-IgM antibody and
resulted in inhibition of IgM antibody secretion and re-
duced expression of cluster of differentiation CD86 [13].
Another study by Lee et al. 2018 [14] demonstrated that
piperine in combination with gamma-aminobutyric acid
(GABA) mediated p38 and JNK MAPK activation, which
increased EPO and EPO-R expression, resulting in up-
regulation of IL-10 and NF-κB. Alkaloids like curcumin,
berberine, and palmatine were identified from VG. The
anti-viral effect of curcumin on Zika and chikungunya
viruses has been well established [15]. The literature
showed that curcumin mediates its anti-viral activity
through various mechanisms. Curcumin has been reported
to inhibit the Japanese encephalitis virus by dysregulated
ubiquitin-proteasome system and an accumulation of ubi-
quitinated proteins [16].Curcuminwasalsoreportedtoin-
hibit various virus replications like Rift Valley fever virus
and hepatitis C virus [17,18]. Moreover, curcumin was
shown to impact HCV replication through binding and fu-
sion [19] and similar results were reported in the case of
ZIKV and CHIKV. HIV-1 integrase activity of curcumin
was also reported previously [20]. Various pharmacological
activities of berberine such as anti-oxidant, anti-bacterial,
anti-inflammatory, anti-viral, nephroprotective, and cardio-
protective have been reported earlier [21]. Anti-viral activity
of berberine against human cytomegalovirus has been
reported previously [22]. The immunomodulatory ef-
fect of berberine was validated in many previous liter-
atures [2325].
Currently, there are no available vaccines or specific
medicines for the treatment of COVID-19. In light of
the outbreak, various treatment modalities have been
considered, including herbal medicine, which has been
widely used during the past epidemic outbreaks, such as
severe acute respiratory syndrome (SARS) and H1N1 in-
fluenza. The phytochemicals identified from IK, MMG,
and VG are active molecules with potential biological
properties such as anti-viral, anti-inflammatory, and im-
munomodulatory activities.
5 Conclusion
COVID-19 pandemic is a global challenge for human
health, and researchers are urgently seeking medicine
for it. Currently, the treatment options for COVID-19
are limited due to non-availability of vaccines or specific
medicines. In this context, the search for traditional
herbal medicine is also a viable strategy for COVID-19
management. The present study on selected Ayurveda
medicines provided valuable scientific data regarding the
active ingredients of the drugs tested with proven thera-
peutic potentials like anti-viral, immunomodulatory, and
anti-inflammatory activities.

... Hyphenated techniques such as liquid chromatography-mass spectrometry (LC/MS) are being used for the metabolite profiling and characterization of active constituents of medicinal plants. LC/MS based plant metabolomics studies are an important aspects of medicinal plants research (Sulaiman et al 2021;Jorge et al 2016). ...

Holarrhena pubescens is an important medicinal plant used in Ayurveda and other traditional systems of medicine. Bark of this tree is used in Ayurveda to treat dysentery, especially amoebic dysentery. This study is aimed at exploring the possibilities of using secondary branches of H. pubescens as a sustainable alternative to its bark, which is subject to overexploitation due to its high medicinal demands. Comparative chemical evaluation has been carried out in the bark and secondary branches of this species using various spectrophotometric and high-performance thin-layer chromatographic studies. Detailed metabolite profiling was done by liquid chromatography mass spectroscopic evaluation. The result showed that the chemical constituents of both bark and secondary branches are almost similar; however, the abundance of individual compounds showed differences. Concentrations of phenolics and flavonoids are found to be higher for bark than its secondary branches. Minor variations of chemical constituents were also observed among the different collections. LC/MS analysis showed that major metabolites are common for both bark and branches, which provided a lead for further studies to ensure the therapeutic potential.
... Multiple chromatographic and mass spectroscopic studies are required for the detailed characterization of herbal medicines. [11] Large range of LC/MS instruments are currently available for MS-based plant metabolomics studies like triple quadrupole (QqQ), quadrupole ion trap (QIT), quadrupole time of flight (QTOF), quadrupole Orbitrap, triple quadrupole-linear ion trap (QTRAP) etc. High resolution mass spectrometry enables the compound identification easier with high degree of accuracy. Detailed fragmentation and structural information from intact ionized species can be obtained by performing collision-induced dissociation (CID) on a tandem MS instrument. ...

India is one of the richest countries in terms of biodiversity with variety of agroclimatic zones; from snow-clad mountains to dry deserts; and from lush green forests to coral reefs. Our herbal wealth constitutes more than 8,000 species and accounts for around 50 % of all higher flowering plant species of India; around 70 % of the medicinal plants in the country are spread across the tropical forests of Western Ghats. The demand for medicinal plants is increasing exponentially both in domestic and international market as large number of plants are being used for healthcare products, nutraceutical, phytopharmaceuticals, cosmetics, fragrances, flavours and natural colouring agents. Conversely, an important problem the herbal industry faces today is the non-availability of genuine herbs in required quantities leading to adulteration and unauthorized substitution which affects the quality of medicines adversely. Ensuring quality, safety and consistency of herbal medicine is an important prerequisite of the industry. An investigative approach that combines taxonomy, pharmacognosy, phytochemistry and molecular biology offers a useful platform for the overall quality evaluation of herbal medicines.
... [5,6] Successful utilization of many Ayurvedic formulations and regimens in the prevention and management of COVID-19 has been witnessed since its emergence [2,7,8] Numerous Ayurveda medicines such as AYUSH-64, Indukantham Kwatham, Vilvadi Gulika, and Mukkamukkatuvadi Gulika have been studied to be beneficial in COVID-19 due to its anti-viral and immunomodulatory effects. [9,10] Considering the nature of the virus, clinical scenario and the mutations and waves of the infections coming in, holistic management of COVID-19 should be contemplated, integrating Ayurvedic medication into the standard supportive care protocol, with an integration of Ayurvedic medication in the standard supportive care protocol. The integration can improve clinical outcomes and can help in managing any long-term complications as well as by fundamentally supporting host immunity. ...

Background The constructive role of Ayurveda in managing COVID-19 has been widely discussed, with identified herbs showing immunomodulatory and anti-viral potential. However, clinical trials examining their safety and efficacy are limited. Aim The aim of this study is to determine the efficacy of COROPROTECT kit, a proprietary Ayurvedic formulation, in COVID-19. Materials and method Randomized, placebo-controlled trial with 312 mild to moderate hospitalized COVID-19 patients. Groups received COROPROTECT or placebo for 10 days alongside standard care. Results The outcome measures included the number of days taken to reverse the reverse transcriptase-polymerase chain reaction (RT-PCR) status, reduction in symptoms and inflammatory markers. Fisher exact test was used to analyze the changes between categorical variables, whereas the comparative effect of therapy in both groups on inflammatory markers and safety biochemical parameters was analyzed using Student’s t test. A total of 300 patients completed the study without any adverse events. The COROPROTECT kit group exhibited a statistically significant higher percentage of patients testing negative on days 4, 7, and 10 compared to the placebo group. A within group analysis showed that trial group to significantly reduced the levels of C-reactive protein ( P = 0.03), lactate dehydrogenase ( P < 0.001), and interleukin-6 ( P = 0.01). Subjects of the trial group experienced complete relief from cough (69.33%), breathlessness (65.33%), and fatigue (62.67%) within 4 days. In contrast, the placebo group had 20%–40% of participants with mild symptoms persisting until day 10. Conclusion This study suggests potential future implications, indicating a faster RT-PCR negativity, reduced COVID-19 severity, and inflammatory markers, along with early symptomatic recovery. The COROPROTECT kit proved safe, facilitating an accelerated clinical recovery compared to conventional care.
... Based on the above mentioned strategies, a search for possible plants with the following features may assist in the establishment of natural plant-derived antiviral medicines to combat the pandemic disease da Silva Antonio et al., 2020).

Janapadodhvansa (also spelled as janapadodhvamsa) means destruction of communities due to a common cause. The affliction of diseases in society disrupting the physical, psychological, social health of community is phenomenon observed since inception of life on the earth. The pandemic and epidemic situations are considered to be as old as human evolution. Ayurveda texts have thus also extensively mentioned the pandemic conditions at various places commonly referred to as janapadodhvansa, maraka or janamara. Acharya Charak has explained the concept of janapadodhvansa in vimana sthana of the treatise Charak samhita. The concept of janapadodhvansais thus reference point for the description of disease origin and spread in the population highlighting the principles of epidemiology in ayurveda.

İnsanoğlu; insanlık tarihinin başlangıcından itibaren salgın hastalıklarla savaşmıştır. Günümüzde de salgın hastalıklarla olan bu savaş devam etmekte olup yeni salgın COVID-19 2019 aralık ayında Çin'in Wuhan kentinde ortaya çıkmıştır. Dünya Sağlık Örgütü (DSÖ) yaşamı tehdit eden bir hastalık olan COVID-19' u Çin ve diğer uluslararası ülkelerde artan vaka ve ölüm oranlarını dayanak göstererek 30 Ocak 2020'de küresel bir halk sağlığı sorunu olarak ilan etmiştir. Dünyaya hızlı bir şekilde yayılan salgının ülkemizdeki ilk vakası 11 Mart 2020'de tespit edilmiştir. Ülkemizde ilk vakadan sonra salgın daha da artmış olup sağlığın korunması ve hastalığın tedavisi önemli hale gelmiştir. Pandeminin ilk zamanlarında virüsün yayılmasının engellenmesi ve hastalığın tedavisi için ilaç ve aşı bulma çalışmaları yapılmıştır. Bu süreçte COVID-19 tedavisi için güvenilir ve etkinlik açısından kanıtlanmış özel bir antiviral ilaçta bulunmamaktaydı. Ancak COVID-19 aşısı için olumlu aşı çalışmaları mevcuttu. Korona virüs aşı bulunana kadar salgın krizinin bir an önce atlatılabilmesi için tüm kaynakların kullanılması gerekiyordu. Bunun için hastaların tedavi uygulamalarına yardımcı olmak, ilaç ve aşı geliştirilinceye kadar hastalığa yakalanma oranı ve ölüm oranını en aza indirmek amacıyla bilimsel temellere dayalı tamamlayıcı ve alternatif tıp (TAT) yöntemlerinin yararlı olabileceği düşünülmüştür.

COVID-19 pandemic caused by the novel SARS-CoV-2 has impacted human livelihood globally. Strenuous efforts have been employed for its control and prevention; however, with recent reports on mutated strains with much higher infectivity, transmissibility, and ability to evade immunity developed from previous SARS-CoV-2 infections, prevention alternatives must be prepared beforehand in case. We have perused over 128 recent works (found on Google Scholar, PubMed, and ScienceDirect as of February 2023) on medicinal plants and their compounds for anti-SARS-CoV-2 activity and eventually reviewed 102 of them. Te clinical application and the curative effect were reported high in China and in India. Accordingly, this review highlights the unprecedented opportunities offered by medicinal plants and their compounds, candidates as the therapeutic agent, against COVID-19 by acting as viral protein inhibitors and immunomodulator in (32 clinical trials and hundreds of in silico experiments) conjecture with modern science. Moreover, the associated foreseeable challenges for their viral outbreak management were discussed in comparison to synthetic drugs.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel coronavirus accountable for the coronavirus disease 2019 (COVID-19) that has led to many fatal cases worldwide. It causes a severe acute respiratory syndrome, a hyperinflammatory response, vascular damage, microangiopathy, and widespread thrombosis. Vaccines, interferon therapies, and small-molecule drugs may be among the various alternatives for managing or preventing emerging SARS-CoV-2 infections. New interventions, on the other hand, are likely to take months to years to develop. Furthermore, existing antiviral agents commonly develop viral resistance along with certain side effects. Therefore, effective prevention and treatment medications without side effects against human coronavirus are in urgent need. Indian and Chinese traditional medicine have suggested some natural products for the prevention, treatment, and rehabilitation of the diseases, including COVID-19 and various herbs and mushrooms that have been reported to possess potential antiviral and anti-inflammatory activities. Therefore, in this pandemic, traditional medicines pose a ray of hope for human health. The Ministry of Ayush, India, has also recommended a number of therapies to increase immunity in addition to ayurvedic treatments. Thus, the probability of naturally occurring substances as successful treatments against COVID-19 may seem hopeful due to their diverse biological and therapeutic properties. This review focuses on the latest updates of Ayurvedic herbs and spices as promising approaches for treatment during this devastating pandemic situation.

Background: Severe acute respiratory syndrome (SARS) has been initiating pandemics since the beginning of the century. In December 2019, the world was hit again by a devastating SARS episode that has so far infected almost four million individuals worldwide, with over 200,000 fatalities having already occurred by mid-April 2020, and the infection rate continues to grow exponentially. SARS coronavirus 2 (SARS-CoV-2) is a single stranded RNA pathogen which is characterised by a high mutation rate. It is vital to explore the mutagenic capability of the viral genome that enables SARS-CoV-2 to rapidly jump from one host immunity to another and adapt to the genetic pool of local populations. Methods: For this study, we analysed 2301 complete viral sequences reported from SARS-CoV-2 infected patients. SARS-CoV-2 host genomes were collected from The Global Initiative on Sharing All Influenza Data (GISAID) database containing 9 genomes from pangolin-CoV origin and 3 genomes from bat-CoV origin, Wuhan SARS-CoV2 reference genome was collected from GeneBank database. The Multiple sequence alignment tool, Clustal Omega was used for genomic sequence alignment. The viral replicating enzyme, 3-chymotrypsin-like cysteine protease (3CLpro) that plays a key role in its pathogenicity was used to assess its affinity with pharmacological inhibitors and repurposed drugs such as anti-viral flavones, biflavanoids, anti-malarial drugs and vitamin supplements. Results: Our results demonstrate that bat-CoV shares > 96% similar identity, while pangolin-CoV shares 85.98% identity with Wuhan SARS-CoV-2 genome. This in-depth analysis has identified 12 novel recurrent mutations in South American and African viral genomes out of which 3 were unique in South America, 4 unique in Africa and 5 were present in-patient isolates from both populations. Using state of the art in silico approaches, this study further investigates the interaction of repurposed drugs with the SARS-CoV-2 3CLpro enzyme, which regulates viral replication machinery. Conclusions: Overall, this study provides insights into the evolving mutations, with implications to understand viral pathogenicity and possible new strategies for repurposing compounds to combat the nCovid-19 pandemic.

This is the first known case of a Coronavirus disease (COVID-19) positive patient treated entirely with Ayurveda. So far in Modern Western Medicine (MWM), no cure has been found which is specific to COVID-19. The only literature relevant to the treatment of Coronavirus disease has surfaced from Traditional Chinese Medicine (TCM). TCM which was extensively used to control the epidemic in China, also consists of herbal medicines similar to Ayurveda. In this case, the patient, who was familiar with the use of Ayurvedic medicines, fully aware that no proven cure exists in MWM, decided to entirely rely on the limited Ayurvedic medicines that he had in his possession at the time of falling ill. Despite the patient presenting with symptoms, namely high fever, severe body pain and severe cough, along with many of the other associated symptoms of COVID-19, the progress of the disease could be arrested within a short period by being exclusively on Ayurvedic medicines. This illustrates that there is a wide scope to explore the variety of pertinent medicines present in Ayurvedic pharmacopoeia which can be used more rationally to suit every stage of the disease. Being the first-of -its-kind it is a valuable contribution to scientific literature from the world of Ayurveda. This should encourage the healthcare policy makers to quickly use Ayurveda to bring COVID-19 pandemic under control in India, as they seemed to have demonstrated it in China with TCM.

World community is facing an unprecedented pandemic of novel corona virus disease (COVID-19) caused by Severe Acute Respiratory Syndrome Corona virus 2 (SARS-CoV- 2). The disease has spread globally with more than 1.43 million confirmed cases and 82,100 deaths as of April 8, 2020. Despite worldwide efforts to contain it, the pandemic is continuing to spread for want of a clinically-proven prophylaxis and therapeutic strategy. The dimensions of pandemic require an urgent harnessing of all knowledge systems available globally. Utilization of Traditional Chinese Medicine in Wuhan to treat COVID-19 cases sets the example demonstrating that traditional health care can contribute to treatment of these patients successfully. Drawing on the Ayurveda classics, contemporary scientific studies, and experiential knowledge on similar clinical settings, here we propose a pragmatic plan for intervention in India. We provide a plan for graded response, depending on the stage of infection among individuals, in a population. Notwithstanding the fact that no system of medicine has any evidence-based treatment for COVID-19 as yet, clinical interventions are required to be put in place. Therefore, pragmatic strategy proposed here for Ayurveda system of medicine requires immediate implementation. It will facilitate learning, generate evidence and shall be a way forward.

Viral infections are responsible for many illnesses, and recent outbreaks have raised public health concerns. Despite the availability of many antiviral drugs, they are often unsuccessful due to the generation of viral mutants and less effective against their target virus. Identifying novel antiviral drugs is therefore of critical importance and natural products are an excellent source for such discoveries. Coumarin is one such natural compound that is a potential drug candidate owing to its properties of stability, solubility, and low toxicity. There are numerous evidences showing its inhibitory role against infection of various viruses such as HIV, Influenza, Enterovirus 71 (EV71) and coxsackievirus A16 (CVA16). The mechanisms involve either inhibition of proteins essential for viral entry, replication and infection or regulation of cellular pathways such as Akt-Mtor (mammalian target of rapamycin), NF-κB (nuclear factor kappa-light-chain-enhancer of activated B cells), and anti-oxidative pathway including NrF-2 (The nuclear factor erythroid 2 (NFE2)-related factor 2). This review summarizes the present state of understanding with a focus on coumarin's antiviral effect and their possible molecular mechanisms against Influenza virus, HIV, Hepatitis virus, Dengue virus and Chikungunya virus.

The novel Coronavirus disease 2019 (COVID-19) is caused by SARS-CoV-2, which is the causative agent of a potentially fatal disease that is of great global public health concern. The outbreak of COVID-19 is wreaking havoc worldwide due to inadequate risk assessment regarding the urgency of the situation. The COVID-19 pandemic has entered a dangerous new phase. When compared with SARS and MERS, COVID-19 has spread more rapidly, due to increased globalization and adaptation of the virus in every environment. Slowing the spread of the COVID-19 cases will significantly reduce the strain on the healthcare system of the country by limiting the number of people who are severely sick by COVID-19 and need hospital care. Hence, the recent outburst of COVID-19 highlights an urgent need for therapeutics targeting SARS-CoV-2. Here, we have discussed the structure of virus; varying symptoms among COVID-19, SARS, MERS and common flu; the probable mechanism behind the infection and its immune response. Further, the current treatment options, drugs available, ongoing trials and recent diagnostics for COVID-19 have been discussed. We suggest traditional Indian medicinal plants as possible novel therapeutic approaches, exclusively targeting SARS-CoV-2 and its pathways.

Background: Previous studies on the pneumonia outbreak caused by the 2019 novel coronavirus disease (COVID-19) were based on information from the general population. Limited data are available for pregnant women with COVID-19 pneumonia. This study aimed to evaluate the clinical characteristics of COVID-19 in pregnancy and the intrauterine vertical transmission potential of COVID-19 infection. Methods: Clinical records, laboratory results, and chest CT scans were retrospectively reviewed for nine pregnant women with laboratory-confirmed COVID-19 pneumonia (ie, with maternal throat swab samples that were positive for severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]) who were admitted to Zhongnan Hospital of Wuhan University, Wuhan, China, from Jan 20 to Jan 31, 2020. Evidence of intrauterine vertical transmission was assessed by testing for the presence of SARS-CoV-2 in amniotic fluid, cord blood, and neonatal throat swab samples. Breastmilk samples were also collected and tested from patients after the first lactation. Findings: All nine patients had a caesarean section in their third trimester. Seven patients presented with a fever. Other symptoms, including cough (in four of nine patients), myalgia (in three), sore throat (in two), and malaise (in two), were also observed. Fetal distress was monitored in two cases. Five of nine patients had lymphopenia (<1·0 × 10⁹ cells per L). Three patients had increased aminotransferase concentrations. None of the patients developed severe COVID-19 pneumonia or died, as of Feb 4, 2020. Nine livebirths were recorded. No neonatal asphyxia was observed in newborn babies. All nine livebirths had a 1-min Apgar score of 8-9 and a 5-min Apgar score of 9-10. Amniotic fluid, cord blood, neonatal throat swab, and breastmilk samples from six patients were tested for SARS-CoV-2, and all samples tested negative for the virus. Interpretation: The clinical characteristics of COVID-19 pneumonia in pregnant women were similar to those reported for non-pregnant adult patients who developed COVID-19 pneumonia. Findings from this small group of cases suggest that there is currently no evidence for intrauterine infection caused by vertical transmission in women who develop COVID-19 pneumonia in late pregnancy.

Aims The aim of this study was to evaluate gamma-aminobutyric acid (GABA)- and piperine-induced erythropoietin (EPO) and EPO-receptor expression. Materials and methods The effect of GABA and piperine on cell viability was examined using kidney epithelial cells. Expression levels of EPO and EPO-R mRNA and protein were evaluated in response to GABA and piperine treatments. GABA- and piperine-mediated activation of the mitogen-activated protein kinase (MAPK) signaling pathway was investigated. Additionally, EPO function was evaluated using conditioned media containing EPO. The GABA receptor type involved in this process was identified. Key findings Messenger RNA and protein expression levels of EPO and EPO-R significantly increased in response to treatment with GABA, piperine, or the combination of both, compared with control. GABA plus piperine synergistically enhanced EPO and EPO-R expression through p38 and c-Jun N-terminal kinase (JNK) MAPK signaling pathways, but not through the extracellular signal-regulated kinase (ERK) MAPK pathway. SB203580 and SP600125 (p38 and JNK pathway inhibitors, respectively) attenuated GABA plus piperine-induced EPO and EPO-R expression. Treatment of macrophages with EPO-containing conditioned media induced mRNA expression of interleukin (IL)-10 and nuclear factor (NF)-κB due to the interaction between EPO and EPO-R. Interestingly, GABA-induced EPO and EPO-R expression was mediated through GABAA, not GABAB, receptor activation. Significance These findings demonstrate that GABA plus piperine-mediated p38 and JNK MAPK activation increases EPO and EPO-R expression, resulting in up-regulation of IL-10 and NF-κB.
