Oil extracted from <em>Ceiba pentandra</em> seed was studied to explore its suitability for ethnomedical uses with a special emphasis on its physiochemical characterization, antimicrobial behavior and spectrophotometric parameters. Some of the physiochemical properties were examined and compared with those of standard oils and, in particular, any common characteristics with cotton seed oil were evaluated. Spectrophotometric analysis of oil was carried out to obtain information regarding the types, numbers and position of chromophores and auxochrome, and saturated and unsaturated compounds. Crude <em>Ceiba pentandra</em> oil was found to show good to moderate activity against bacteria, and in particular Gram +ve (<em>B. cereus, B. subtilis </em>and <em>S. aureus</em>) and Gram -Ve (<em>E. coli</em> and <em>P. aeurignosa</em>) and fungal stains, more specifically <em>Aspergillus flavans</em>, <em>Aspergillus niger</em>, <em>Candida albicans</em> and <em>Saccharomyces cerevisiae</em>. Maximum activity was observed on bacterial strains compared with fungal strains. Among bacteria, <em>Bacillus subtilis</em> was highly sensitive; fungi were less susceptible to oil and <em>Saccharomyces cerivisiae </em>were the most susceptible. Minimum inhibitory concentrations and minimum bactericidal and fungicidal concentrations of the seed oil varied between 3 to 10 mg/50 μL against all bacterial and fungal strains used in this study. In conclusion, <em>Ceiba pentandra</em> oil is a natural antimicrobial agent and could have therapeutic potential.

New Compounds

The multi-step synthesis, physico-chemical characterization, and biological activity of novel valine-derived compounds, i.e., N-acyl-α-amino acids, 1,3-oxazol-5(4H)-ones, N-acyl-α-amino ketones, and 1,3-oxazoles derivatives, bearing a 4-[(4-chlorophenyl)sulfonyl]phenyl moiety are reported here. The structures of the newly synthesized compounds were confirmed by spectral (UV-Vis, FT-IR, MS, 1H- and 13C-NMR) data and elemental analysis results, and their purity was determined by RP-HPLC. The new compounds were assessed for their antimicrobial activity and toxicity to aquatic crustacean Daphnia magna. Also, in silico studies regarding their potential mechanism of action and toxicity were performed. The antimicrobial evaluation revealed that the 2-{4-[(4-chlorophenyl)sulfonyl]benzamido}-3-methylbutanoic acid and the corresponding 1,3-oxazol-5(4H)-one exhibited antimicrobial activity against Gram-positive bacterial strains and the new 1,3-oxazole containing a phenyl group at 5-position against the C. albicans strain.

Objective: The present study was done to see the effect of biologically synthesized CuO-NPs (Copperoxide nanoparticles) on the growth of bacterial strains. Methods: Physico-chemical characterization of CuO-NPs was done by UV-Vis-spectrophotometer, XRD, FE-SEM, and EDS. The disc plate diffusion assay was used to evaluate the anti-bacterial effect of CuNPs. Results: This study has shown a promising anti-bacterial activity of biosynthesized CuO-NPs at different concentrations ranging from 10 to 100 µg/ml against Escherichia coli and Staphylococcus aureus bacteria. Conclusion: Nanoparticles (NPs) are small size particles between range 1 to 100 nm which expand their physical and chemical properties due to high surface area. The present study reveals that there may be possible utilization of biosynthesized CuO NPs for the treatment of bacterial infectious disease in near future.
