Article
Aristolochic acid Ⅰ is a nephrotoxic compound and exist in some traditional Chinese medicines at trace level. Up to now, specific enrichment of aristolochic acid Ⅰ remains important procedure and key problem in its analysis. In this study, melamine was proposed as the recognition unit and grafted on the surface of metal-organic framework to fabrica...

1. In this study, UC rat model was established by administration of 5% (w/v) dextran sulfate sodium, and the pharmacokinetics of verapamil and norverapamil were evaluated in normal and UC rats using UPLC-MS/MS after oral administration of 5 mg/kg and 50 mg/kg verapamil. 2. The peak concentration (Cmax) and the area under plasma concentration–time c...

Introduction: Chronic kidney disease (CKD) promotes hypertrophy and fibrosis in heart, and increases the risk of cardiovascular mortality. Ferric citrate is a dietary phosphate binder used to control hyperphosphatemia in CKD patients. It has been shown to raise iron stores, improve anemia and secondary hyperparathyroidism, and decrease vascular ca...
Article
Chronic kidney disease (CKD) causes anemia and impairs intestinal iron absorption. However, use of the phosphate binder, ferric citrate (FC), increases body iron stores and hemoglobin levels in CKD patients. By intensifying oxidative stress and inflammation iron overload can accelerate CKD progression. Present study explored the route of absorption...
Article
Chronic kidney disease (CKD) results in various central nervous systems (CNS) disorders including cognitive dysfunction, depression, anxiety, movement disorders, seizures and encephalopathy. Uremic retention products, oxidative stress, inflammation and impaired blood-brain barrier have been implicated as the major mediators of CKD-induced CNS disor...

Downregulation of P-glycoprotein (P-gp) is implicated in the pathophysiology of inflammatory bowel disease (IBD). Berberine, a principal isoquinoline alkaloid extracted from Berberis species, has been reported to exhibit therapeutic potential in IBD. In this study, we used a dextran sulfate sodium (DSS)-induced colitis rat model to evaluate the eff...
Article
Introduction: Systemic inflammation and oxidative stress play a central role in the pathogenesis of cardiovascular disease and numerous other complications of CKD. Recent studies demonstrated that consumption of a diet enriched with amylose (HAM-RS2), attenuates oxidative stress and inflammation, and improves intestinal microbiome in CKD rats. The...
Article
Ethnopharmacological relevance: Polysaccharides and small molecules commonly co-exist in decoction of traditional Chinese medicines (TCMs). Our previous study outlined that ginseng polysaccharides (GP) could interact with co-existing ginsenosides to produce synergistic effect in an over-fatigue and acute cold stress model via gut microbiota involv...
Article
Background: Chronic kidney disease (CKD) is associated with cardiac hypertrophy, fibrosis and increased risk of cardiovascular mortality. LCZ696 (Sacubitril/valsartan) is a promising agent which has shown significant potential in treatment of heart failure. We hypothesized that LCZ696 is more effective than valsartan alone in treatment of cardiova...

Progressive deterioration of kidney function in chronic kidney disease (CKD) is mediated by hypertension, oxidative stress, inflammation, and fibrosis. Renin-angiotensin blockade is commonly used to retard CKD progression. In addition, vasoactive peptides have been shown to reduce blood pressure and exert antioxidant, anti-inflammatory and anti-fib...
Article
Substandard and counterfeit anti-diabetic medicines directly influence the health and impose a great danger to individual patients and to public health. Counterfeiting has become a serious and underreported problem in the pharmaceutical industry. There are a large number of counterfeit medicines flooded in anti-diabetic markets which effect human h...

P-Glycoprotein dysregulation and microbial imbalance have been implicated in inflammatory bowel diseases. Here we found that oral dosing of Mori Cortex, the root bark of Morus alba L. markedly alleviated inflammatory responses, reinstated microbial balance, and enhanced P-glycoprotein (P-gp) expression in rat colitis (UC) induced by oral administra...
Article
In this work, a new molecularly imprinted solid phase extraction protocol was developed for the selective extraction and purification of glycyrrhizic acid from liquorice roots in aqueous media. The molecularly imprinted polymers (MIPs) for glycyrrhizic acid were prepared by using bismethacryloyl-β-cyclodextrin and methacrylic acid as double functio...

A vast number of structural modifications have been performed for khellactone derivatives (KDs) that have been widely concerned owing to their diverse biological properties, including anti-hypertension, anti-HIV, reversing P-glycoprotein (P-gp) mediated multidrug resistance, and anti-inflammation effects, to find the most active entity. However, ex...
Article
Highly selective molecularly imprinted polymers on the surface of silica gels were prepared by a sol-gel process and used as solid-phase extraction adsorbents for the specific recognition, enrichment and detection of cloxacilloic acid in cloxacillin. The obtained polymers were characterized by scanning electron microscopy, FTIR spectroscopy, nitrog...

As a commonly employed traditional Chinese medicine, Peucedani Radix (Qian-hu in Chinese), which consists of the dried roots of Peucedanum praeruptorum Dunn, has a long history of application for the treatment of cough with thick sputum and dyspnea, nonproductive cough and upper air-way infections in traditional medicinal practice. The current revi...

Herbal medicines (HMs) are believed to produce holistic action through the synergistic effects of both major and minor components. In current study, a practical strategy was proposed for comprehensive characterization of the chemical constituents in HMs. Mori Cortex (MC), which contains diverse chemical constituents and consequently exhibits a broa...
Article
Active components of herbal medicines usually become trace in the body, owing to absorption/distribution barriers and/or biotransformation hurdles. The goal of this study was to detect and identify angular-type pyranocoumarins (APs) in biological samples (plasma, urine and feces) obtained from rats after oral intake of Peucedani Radix extract (PRE)...
Article
Enantioselective pharmacokinetics and metabolism were revealed for (±)-praeruptorin A (PA), the major bioactive component in Peucedani Radix. In the present study, we deal with the development and validation of two enantioselective methods for enantiospecific determination of PA enantiomers (D-PA/L-PA) and their metabolites, cis-khellactone enantio...
Article
Green tea consists of the dried leaves of Camellia sinensis, and enjoys great popularity all over the world due to its pleasant taste and positive impact on human health. It has also been regarded as a natural medicine containing great amounts of caffeine (CA), gallic acid (GA), theanine (TH), and tea polyphenols, mainly including epicatechin (EC),...

Enantiomers and diastereoisomers of angular-type pyranocoumarins (APs) are abundant in Peucedani Radix (Chinese name: Qian-hu), eliciting distinct activities in vitro and in vivo. Our ongoing investigation on APs yielded eight pairs of enantiomers (1a and 1b, 2a and 2b, 3a and 3b, 4a and 4b, 5a and 5b, 6a and 6b, 7a and 7b and 8a and 8b) via enanti...
Article
In vitro cell models are easy, reproducible, and cost-effective tools for tracking drug absorption rates and for elucidating related mechanisms. Traditionally, before introduction into an analysis system, samples crossing an in vitro cell membrane usually undergo complicated processes including precipitation, centrifugation, and even filtering. In...

(±)-Praeruptorin A (PA) is the major component of Peucedani Radix. The present study investigated stereoselectivity in PA metabolism in liver microsomes of rats (RLMs) and humans (HLMs), for the first time. PA was enantioseparated by semi-preparative chiral HPLC. Metabolic profiles of the dextrorotatory (dPA) and the levorotatory (lPA) forms in HLM...
