    ABSTRACT: Conformational stability of various 5-substituted orotic acid derivatives was studied by applying linear free energy relationships (LFER) to the 13CNMR chemical shifts. The correlation analysis for the substituent-induced chemical shifts (SCS) with inductive ( I), and various resonance (R) parameters were carried out through SSP (Single Substituent Parameter) and DSP (Dual Substituent Parameter) methods, and multiple regression analysis. Good Hammett correlations for all carbons were obtained, while electrophilic substituent constants better fitted for C2 carbon with electron-donor substiteunts. Conformational analysis of various derivatives using RB3LYP/6-311++G (3df,3dp) DFT method, together with 13C NMR data suggest that most of the substituted orotic acid derivatives exist in planar conformation, except nitro and alkyl substituted derivatives. Internal rotation of carboxylic group showed significant impact on the extent of conjugative interaction making syn conformation more stable in all the derivatives studied. Further, of all 5-substituted orotic acid derivatives, diketo form proved to be the most stable form compared to zwitterionic and enol tautomeric forms. Optimized geometries and transmission effects of particular substituent through well-defined π-resonance units suggest that these units behave as both isolated as well as conjugated fragments, depending on the type of substituent.

    ABSTRACT: The growing need of antimicrobial agent for novel therapies against multi-drug resistant bacteria has drawn researchers to green nanotechnology. Esp ecially, eco-friendly biosynthesis of silver nanoparticles (Ag NPs) have showed its interesting impact against bacterial infection in laboratory research. In this study, a simple method was developed to form AgNPs at room temperature, bio-reduction of silver ions from silver nitrate salt by leaf extract from Ocimum gratissimum. The AgNPs appear to be capped with plant proteins, but are otherwise highly crystalline and pure. The AgNPs have a zeta potential of -15 mV, a hydrodynamic diameter of 31 nm with polydispersity index of 0.65, and dry sizes of 18 ± 3 nm and 16 ± 2 nm, based on scanning and transmission electron microscopy respectively. The minimum inhibitory concentrations (MIC ) of the AgNPs against a multi-drug resistant Escherichia coli was 4 μg/mL and the minimum bactericidal concentration (MBC ) was 8 μ g/mL, while the MIC and MBC against a resistant strain of Staphylococcus aureus was slightly higher at 8μ g/mL and 16μ g/mL respectively. Further, the AgNPs inhibited biofilm formation by both E. coli and S. aureus at concentrations similar to the MIC for each strain. Treatment of Escherichia coli and Staphylococcus aureus with AgNPs resulted in damage to the surface of the cells and the production of reactive oxygen species. Both mechanisms likely contribute to bacterial cell death. In summary, this new method appears promising for green biosynthesis of pure AgNPs with potent antimicrobial activity. Key Words: Silver nanoparticles (Ag NPs), green synthesis, Antibacterial activity, Staphylococcus aureus , Escherichia coli.

    ABSTRACT: A series consisting of 30 novel imidazo[4,5-b]pyridine benzohydrazones have been synthesized and evaluated for their antiglycation activity as well as their antioxidative potential. The synthetic part involves a 3-step reaction in which a pyridine diamine was being converted into a imidazo[4,5-b]pyridine, which was then subjected through another reaction to yield benzohydrazide. Subsequently, the attained benzohydrazide of imidazo[4,5-b]pyridine were used to synthesize the target molecules after treating them with the appropriate benzohydrazone derivatives. The derivatives were evaluated for the antiglycation and antioxidant activities. Result obtained showed that di and trihydroxy substituted compounds showed good activity with compound 25 (140.16 ± 0.36 µM) having the most potent antiglycation activity, which is twice lower than Rutin. The results also showed certain correlation between antiglycation activities with DPPH radical scavenging model as well as FRAP which indicated the participation of antioxidative effect in inhibiting glycation activity.

    ABSTRACT: This study aimed to investigate and compare the total phenolic (TPC) and flavonoid (TFC) contents and antioxidant and antibacterial activities of different extracts recovered from Date Palm Pollen collected from Tunisian cultivars of Kerkennah (DPP-K) and Tozeur (DPP-T) using various solvents, including hexane, chloroform, ethyl acetate, acetone, ethanol and water. The results revealed that DPP-T had higher TPC than DPP-K for all solvent extracts, except for hexane, with a value of 237.74 ± 9.58 mg GAE/g for the water extract. The highest level of TFC (75.10 ± 4.37 mg QE/g) was recorded in the acetone DPP-T extract, which was about twice as high as that of DPP-K. A total of eight phenolic compounds were identified and quantified in both extracts by HPLC, namely gallic acid, catechin, caffeic acid, epicatechin, vanillic acid, coumarin, quercitin and rutin. The antioxidant activities of the extracts were screened using DPPH and β-carotene bleaching assays. The results indicated that the DPP-T acetone extract showed the best DPPH scavenging activity (IC50= 46.56 ± 0.28 µg/ml), with no activity being recorded for DPP-K. The DPP-T extract also showed significant effects in terms of the β-carotene test (28.12 ± 0.04 µg/ml) when compared to BHT as a reference standard. The extracts were screened for antimicrobial activity against 10 bacterial and 7 fungal strains, and the results showed that ethyl acetate DPP-K extract exhibited the strongest activity against L. monocytogenes and that the S. aureus strain was most sensitive to DPP-T, with MIC and MBC values of 0.98 mg/ml and 1.95 mg/ml, respectively. Both DPP-T and DPP-K showed strong inhibition effects on the growth of F. oxysporum. Further time kill assays demonstrated the potency of DPP-K and DPP-T ethyl acetate extracts to inhibit the growth of L. monocytogenes and S. aureus, respectively. Overall, the findings suggest that DPP could be considered a promising source of new natural antioxidant and antimicrobial agents for use in various food and pharmaceutical products and formulations. This suggested that the DPP extract is a good potential inhibitor of food spoiling microbial growth and could be a highly effective therapeutic choice for human and plant infections
