In the vision of chemistry, Schiff bases are excellent ligands and play a very important role in drug discovery and development. The Schiff bases and their complexes have been reported in the literature possessing wide applications in biological, clinical, and analytical fields. In outlook of this, new Schiff bases of Sulfonamide drug were synthesized by a very simple reaction and in good yield. The purity of the newly synthesized bases was confirmed by performing TLC in a suitable solvent system. The functional groups present in the targeted Schiff bases were confirmed by FT-IR spectroscopy. Further, all the synthesized compounds were successfully screened for their antimicrobial activity. Among these Schiff bases, the compound containing nitro and fluoro groups shows greater activity than standard drugs. By considering this, there is a need to design more analogs of sulfonamide Schiff bases and correlate the structural modifications with their respective antimicrobial activity to develop a Structure activity...

The current pandemic COVID 19 caused by SARS-CoV-2 is very contagious and causes respiratory disease. Genomic analysis of different strains in SARS-CoV-2 were found to infect different geographical locations of the world (India, USA, and Brazil) and also in different parts of India (Kerala, Surat, and Ahmedabad). These sequences were downloaded from the viral genome sequence database of the National Center for Biotechnology Information (NCBI), and comparative analysis is performed using various computational tools. Comparison of genome size, G+C content, and identified ORFs is performed for different sequences of SARS-CoV-2 isolated from different geographical locations of the world and also from different cities/states of India using various bioinformatics tools. This study concludes that all the sequences isolated from different geographical locations are highly similar to the reference strain of Wuhan, with an identity percentage ranging from 99.56-99.98% and also with the same GC content of 37%. The difference in the identified ORFs of length >150 and a small difference in the identity percentages shows the presence of mutation between...

Diabetes mellitus (DM) is a metabolic disorder in the endocrine system resulting from a defect in insulin secretion, insulin action or both of them. Adverse side effects of chemical drugs for the treatment of diabetes persuaded the use of medical plants. Macrotyloma uniflorum is a traditionally used plant for the treatment of diabetes is packed with powerful plant constituents with polyphenols, flavonoids, and proteins. They are one of the richest antioxidant sources, which lower blood sugar and bear other beneficial health effects. The purpose of this study is to evaluate the effect of ethanolic extract of Macrotyloma uniflorum leaves and stem (EMULS) on Alloxan-induced diabetic rats. In this study 36 Male Sprague Dawley rats, the body weight of 150-200 g was divided into 5 groups. Diabetes was induced by intraperitoneal injection of 150 mg/kg Alloxan. The Macrotyloma uniflorum treatment duration was 30 days in which two doses of extract (200 mg/kg & 400 mg/kg) were orally administered to diabetic rats. Blood glucose levels were estimated with glucometer before treatment,...

Mebendazole is a broad-spectrum anthelmintic drug that is widely used in the treatment of helminthic infections. A simple, accurate, and precise UV-visible spectrophotometric method has been developed and validated for the determination of Mebendazole in tablet formulation. The solvent used for the development of the proposed method was Phosphate buffer 6.8 at 278.6 nm. The Beers’ law was obeyed in the concentration range 5-30 μg/ml. The developed method was validated as per ICH guidelines such as linearity, accuracy, precision, the limit of detection, the limit of quantification, and robustness. The correlation coefficient was found to be 0.999. The accuracy was found between 99.22 to 99.54%. The % RSD of Mebendazole was found to 0.05 to 0.20 for intraday and 0.05 to 0.15 for inter-day precision. The method was found to be precise as % RSD was found to be less than 2%. The LOD and LOQ were found to be 0.986 µg/ml and 2.988 µg/ml, respectively. The results demonstrated that the excipients in the commercial tablets did not interfere...

The purpose of the present work was to prepare and evaluate olmesartan-loaded non-ionic surfactant vesicles (niosomes) to get sustained release by increasing the solubility and bioavailability. Ether injection and thin-film hydration methods were used for the preparation of all formulations as per the factorial design to study the effect of the three independent variables X1 (amounts of span 60), X2 (amount of cholesterol) and X3 (amount of chitosan/ PEG-6000) on two dependent variable Y1 (% DEE), and Y2 (% CDR), respectively. Prepared niosomes were characterized by % DEE, % CDR, FTIR, SEM, and zeta potential, etc. Statistical analysis was performed using ANOVA, and optimization was done by fitting experimental data. After 8 hours dissolution, the minimum and maximum cumulative drug release were observed to be 75.90% and 85.91%, and 77.32% and 88.74% for SPEIM-2 and SPEIM-1 and CHEIM-2 and CHEIM-1; 80.24% and 86.11% and 80.11% and 90.72% for SPTFH-2 and SPTFH-1, and CHTFH-7 and CHTFH-1, respectively. Data obtained from in-vitro dissolution tests were fitted to different kinetic models. FTIR...
