Bhaumik, Asish; Eswaraiah, M. Chinna; Chakraborty, Raja published the artcile< Evaluation of antimicrobial profile of some novel 1, 3, 4-oxadiazole derivatives followed by molecular docking against 3G7E bacterial DNA gyrase>, Electric Literature of 16426-64-5, the main research area is oxadiazole derivative preparation mol docking 3G7E bacterial DNA gyrase; physicochem property antibacterial antifungal oxadiazole derivative preparation.
Design, synthesis, spectral characterization and evaluation of in vitro antimicrobial profile of some novel oxadiazole derivatives I [R = 4-NH2, 2-Br, 4-NO2, etc.] followed by mol. docking studies against bacterial DNA gyrase. The mol. structures of the synthesized compounds were assigned by IR, NMR and mass spectral anal. Mol. docking studies were carried out by AUTO DOCK program. The in vitro antibacterial and antifungal activities of compounds I were done by paper disk diffusion and agar streak dilution technique. In silico mol. docking studies the binding energy of synthesized compounds I were found to be -7.66, -7.67, -7.12, – 7.12, -6.59, -6.46, -7.35, -5.09 which indicated that the compounds had the high binding affinity toward the bacterial DNA gyrase with PDB id 3G7E and inhibit the function topoisomerase in comparison with standard drug ciprofloxacin (-7.44). The preliminary antimicrobial screening displayed that most of the synthesized compounds I were executed moderate to good antimicrobial activity against following bacteria: S. aureus (ATCC 9144), B. subtilis (ATCC 6633), S. epidermidis (ATCC 12228), P. Aeruginosa (ATCC27853), E.coli (ATCC25922), V. cholerrae (ATCC14035) and fungi: A. Niger (ATCC 9029), A.flavus (ATCC204304), C. albicans (ATCC10231) and B. dermatitis (ATCC 26199) etc. All the synthesized compounds I exhibited moderate to good antibacterial and antifungal activity with an MIC range of 12-37μg/mL. Among these eight synthesized oxadiazole derivatives, compound I [R = 4-NH2, 2,4-Cl2, 3,5-(NO2)2] were found to be very good antibacterial as well as antifungal potentiality with an MIC range of 13-12μg/mL; 7-10μg/mL and 15-18μg/mL.
Journal of Drug Delivery and Therapeutics published new progress about Acids Role: RCT (Reactant), RACT (Reactant or Reagent). 16426-64-5 belongs to class bromides-buliding-blocks, and the molecular formula is C7H4BrNO4, Electric Literature of 16426-64-5.
