A series of benzimidazole-linked triazoles hybrids (4a-4u) have been synthesized by simple cyclization, followed by amide coupling and click reaction starting from o-phenylene diamines as substrates with 4-formylbenzioc acid, propargylamine and followed by treatment with aryl azides. The structure of synthesized compounds (4a-4u) was confirmed by spectral techniques. The prepared compounds were screened by the agar well diffusion method against both Gram-positive bacteria (S. aureus, B. subtilis, M. luteus and B. megatherium) as well as Gram-negative bacteria (E. coli, K. pneumoniae, S. typhi and S. paratyphi). Analysis of antibacterial activity profile of synthesized compounds revealed that compounds (4a) and (4c) exhibited prominent activity against all tested Gram positive and Gram-negative...

Introduction: Simvastatin is one of the cholesterol-reducing agents, in the class of statins which is an HMG-CoA reductase inhibitors, used in the treatment of hyperlipidemia. It was categorized in biopharmaceutics classification system (BCS) class II drug, which has low solubility in aqueous media. It is a white-to-off white crystalline and non-hygroscopic powder, insoluble in water, but soluble in methanol, chloroform, and ethanol. Characterization test as FTIR spectroscopy was important to identify the identity of tablets. Tablets properties were evaluated by various physicochemical parameters including dissolution test to examine the equivalence and quality of different marketed brands of Simvastatin. They should comply with the specified pharmacopoeia limit for each test. Objectives: Objective of this study was to analyze the identity and evaluate the quality control parameters of different brands of Simvastatin with the specified pharmacopoeia limit. Method: Different brands of Simvastatin 20 mg tablets were collected by purchasing from local pharmacies in Malaysia. Physicochemical parameters such as weight variation, thickness and diameter measurement were performed. Besides, characterization test using FTIR...

Aim & Background: Silicosis is a prevalent occupational lung disease caused by inhalation of Respirable Crystalline Silica (RCS), leading to irreversible pulmonary fibrosis and restrictive lung disease. This study investigates the therapeutic potential of a combination of methanolic extracts from Glycyrrhiza glabra (licorice) root and Citrus limon (lemon) leaf (CMEGC) against silica-induced silicosis in Wistar rats, leveraging their known antioxidant and anti-inflammatory properties. Methods: The experimental protocol involved dividing rats into six groups, including a control group, a silicosis model group, a Pirfenidone-treated group, and groups treated with the combined extracts at two different dosages (200 mg/kg and 400 mg/kg). Silicosis was induced through aerosol inhalation of SiO2. Various parameters, including body weight, hematological markers, pulmonary edema, TNF-α levels, oxidative stress markers, and lung collagen content, were assessed to evaluate the efficacy of the treatments. Results & Conclusion: Results indicated that the combined extracts significantly improved body weight and reduced pulmonary edema, TNF-α levels and oxidative stress markers compared to the silicosis model group. Histopathological analysis confirmed reduced lung...

Introduction: Phoenix Sylvestris (L.) Roxb also known as date palm or Indian sugar palm, belongs to the Arecaceae family. In our present study, we used the fruit part (epicarp, endocarp). The fruit is very delicious in taste worldwide. It’s flavonoid part is reported with quercetin but its quantification has not yet been reported. Aim: The study aimed to carried out the Quantitative estimation of quercetin from Phoenix sylvestris using a validated HPTLC method. Method: The chromatographic analysis was carried out with the solvent system toluene: ethyl acetate: formic acid (5:4:1, v/v/v) to confirm the presence of quercetin. The HPTLC method was validated by using aluminium-backed silica gel plates with the same solvent system. Quantitative estimation was done by AUC plot. Results: Total Flavonoid Content of the methanolic extract of Phoenix sylvestris is 0.79 mg QE/g. The HPTLC method was good, accurate and specific. The methanolic extract was found to possess 1.07mg/100g of quercetin. Conclusion: This study discussed the validated HPTLC method which is simple, accurate and sensitive tool for...

Introduction: The goal of BTS (Blood Transfusion Service) is to provide safe and quality blood and blood products to needy patients. In developing and underdeveloped countries, there exists a gap between the demands and supply of blood products. Since 100% voluntary blood donation is not achieved, we rely on replacement donors also. Hence this study was attempted to assess the seroprevalence of TTI (transfusion-transmitted infection) in blood donors and to compare the seroreactivity rate between voluntary and replacement donors. Materials and Methods: This retrospective study was done on the blood donors over the period of 4 years from January 2020 to December 2023 in a tertiary care hospital. Donor samples were screened for the five mandatory TTIs, viz., HIV (human immunodeficiency virus), HBV (hepatitis B virus), HCV (hepatitis C virus), syphilis, and malaria. Results: A declining trend in HBV was evident from 2020 to 2023. Prevalence of syphilis was highest in 2022. No marked change noted with HIV and HCV. The TTI rate in non-remunerated voluntary blood donors (NRVBD)...
