It was applied as an efficient and reusable catalyst for the synthesis of 2‐(piperazin‐1‐yl) quinoxaline and benzimidazole derivatives via a one‐pot multiple‐component cascade reaction under green conditions. The results displayed the excellent catalytic activity of Fe3O4@PFBA–metformin@SO3H as an organic–inorganic

Tuberculosis continues to be a major cause of morbidity and mortality all over the world. Various 7-substituted ciprofloxacin derivatives were synthesized and evaluated for antimycobacterial activity in vitro and in vivo against Mycobacterium tuberculosis and for inhibition of the supercoiling activity of DNA gyrase from Mycobacterium smegmatis. Preliminary results indicated that most of the compounds demonstrated better in vitro antimycobacterial activity against M. tuberculosis than ciprofloxacin. Compound 1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-7-[[N-4-[1'-(5- methylisatinyl-ss-semicarbazo)]methyl]N'-piperazinyl]-3-quinoline carboxylic acid (3h) decreased the bacterial load in spleen tissue with 0.76-log(10) protections and was considered to be moderately active in reducing bacterial count in spleen. The results demonstrated the potential and importance of developing new quinolone derivatives against mycobacterial infections. (c) 2005 Published by Elsevier Ltd.

synthesized metal complexes. The ligands and complexes were tested in vitro against bacteria (Escherichia coli and Staphylococcus aureus) and fungi (Fusarium semitectum and Aspergillus flavus) to show that they were active against all the microbial strains examined, and the metal complexes were more active in comparison with the ligands. DNA cleavage activity of the complexes was examined by gel electrophoresis
