Background and Objectives: This study was carried out with the objective to investigate the antibacterial and antifungal activity of the bark of Hardwickia binata Roxb. Materials and Methods: Methanolic extract of bark of Hardwickia binata Roxb. exhibited an inhibitory effect towards the pathogenic organisms. Antimicrobial activity the zone of inhibition values of methanolic extract of bark of Hardwickia binata Roxb. in against two Gram-positive microorganisms viz. Staphytococcus aureus and Bacillus subtilis and two Gram negative microorganisms viz. Escherichia coli and Pseudomonas aeruginosa showed significant activity. Antifungal activity of methanolic extract of bark of Hardwickia binata Roxb. in against two microorganism, Candida albicans, and Aspergillus niger, showed significant activity. Results: The results showed that the remarkable inhibition of the bacterial growth was shown against the tested organisms. The phytochemical analyses of the plants were carried out. The microbial activity of the Hardwickia binata was due to the presence of various secondary metabolites. Conclusion: Hence, these plants can be used to discover bioactive natural products that may serve AS leads in...

The aim of the present work is to develop and optimize solid lipid nanoparticles (SLNs) of pomalidomide with the aid of Box-Behnken design (BBD). A design space with three formulation variables at three levels was evaluated in BBD. Amount of lipid (A), surfactant (B), and co-surfactant (C) were selected as independent variables, whereas particle size (Y1), entrapment efficiency (Y2), and percentage drug release after 12 h (Y3) as responses. Pomalidomide-SLNs were prepared by hot emulsification/ ultra-sonication method and evaluated for responses to obtain optimized formulation. The effect of different levels of factors was evaluated for the particle size, PDI, zetapotential, entrapment efficiency, and % cumulative drug released. Kinetic model fitting for all pomalidomide SLN formulations was done to interpret the release rate. Characterization for the optimized formulation was done by FTIR, SEM, and stability studies. The optimized formulation PLF15 with 6% of tricapric as lipid, 6% of poloxamer 188 as surfactant and 2% eupikuron 200 of co-surfactant used in the nanoparticles with 126.59 ± 1.17 nm of size, 0.172...

A simple, accurate, precise, reproducible, economical UV spectrophotometric method has been developed and validated for simultaneous estimation of Hydroxychloroquine sulfate (HCQ) and Nitazoxanide (NTZ) in a synthetic mixture. Method A by simultaneous equation method, Method B by the first-order derivative method. Method A: simultaneous equation method was based on the measurement of absorbance of nitazoxanide at 345 nm and Hydroxychloroquine Sulfate at 220 nm. Method B: first-order derivative method was based on the measurement of absorbance of HCQ measure at 226 nm (ZCP of NTZ) and absorbance of NTZ measure at 375.50 nm (ZCP of HCQ). The calibration curve was found to be linear in the concentration range 2-10 μg/ml and 5-25μg/ml for HCQ and NTZ, respectively (n=6), with their correlation coefficient of 0.999. The developed method was validated according to the ICH...

The study was designed to study the macroscopic, microscopic, and also physicochemical parameters such as fluorescence analysis, extractive values, ash values, and loss on drying were performed. Therefore, this parameter is essentially used to control the quality of crude drugs and/or herbal drugs/drug products. The moisture content (% LOD) of the leaf powder was found to be 5.10± 0.14 (% w/w), total ash was found to be 12.27 ± 0.3 (% w/w). The amount of acid insoluble ash and water-soluble ash was found to be 14.5 ± 0.25, 6.23± 1.22 (% w/w), respectively. The extractive values of hexane extract were found to be 2.45± 0.26, ethyl acetate extract was found to be5.62±0.17, the water-soluble extractive value of the drug was found to be 9.142 ± 0.58 (% w/w), and the alcohol-soluble extractive value was found to be 14.64 ± 0.28 (% w/w). The results of physicochemical analyses lie within the acceptable limit, which in turn ascertains the quality and purity of leaf...

Objective: To develop a simple, selective, and precise stability-indicating high-performance liquid chromatography method for the simultaneous estimation of acebrophylline and doxofylline in bulk and tablet dosage form. Methods: The chromatographic separation achieved on HiQSil C18 Column (250 × 4.6 mm, 5µm) utilizing a mobile phase Acetonitrile: 10 mM n-hexane sulfonic acid buffer (80: 20, v/v) at a flow rate of 1.0 ml/min with injection volume 20 μl. UV detection was performed at 250 nm. The method was validated as per ICH guidelines. Results: The retention time for acebrophylline and doxofylline was found to be 2.77 min and 9.56 min, respectively. The linear regression analysis data for the calibration plots showed a good linear relationship in the concentration range of 1-10 μg/ml for acebrophylline and 4-24 µg/ml for doxofylline. The percentage recoveries of acebrophylline and doxofylline in the marketed dosage form were found to be 99.91 and 94.24, respectively. The correlation coefficients for acebrophylline and doxofylline were 0.997 and 0.998, respectively. The percentage degradation at different stress conditions like acid,...
