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.
