Synthesis antimicrobial and anticancer activity of N′-arylmethylidene-piperazine-1-carbothiohydrazide
摘要:
Ten newly synthesized thiosemicarbazones of piperazine (3a-3j) were evaluated for their antibacterial and antifungal activity against non-pathogenic strains of Escherichia coli (NCIM 2068), Klebsiella pneumonia (NCIM 2957), Staphylococcus aureus (NCIM 2079), and Bacillus subtilis (NCIM 2921); pathogenic strains of Vibrio cholerae, protease, Candida albicans and Aspergillus niger. All the 10 compounds (3a-3j) were found to be better than Ciprofloxacin against B. subtilis and four molecules (3c, 3d, 3e, and 3h) against S. aureus. Compound 3j, a derivative of benzophenone, has been identified as a potent and promising candidate against C. albicans. The compounds were also evaluated for their anticancer activity against HBL-100 and HL60 cell lines. Compound 3a, a p-hydroxy benzaldehyde derivative, has been identified as a potent and promising candidate.

Based on the antimalarial properties observed for 2-acetylpyridine 4-phenyl-3-thiosemicarbazone (1), an extensive series of related thiosemicarbazones was prepared and tested against Plasmodium berghei in mice. Screening results indicated that the presence of the 2-pyridylethylidene group was critical and that certain phenyl, benzyl, phenethyl, or cycloalkyl groups at N4 of the thiosemicarbazone moiety

oxotechnetium(V) complexes with substituted S-methyldithiocarbazate Schiff bases are described. These six-coordinated complexes show a definite correlation between the strength of the TcO bond and the degree of double bond character of the coordinating CN bond. The relative strength of the TcO bond is mainly determined by the electronic influence of the cis-ligands and not by the presence or influence of a
