| pubmed-article:18677935 | pubmed:abstractText | The scientific literature states that isatin and its derivatives exhibit antibacterial, antifungal, anticonvulsant, cytotoxic and anti-HIV activities. The aim of our study was to enlarge the number of isatin derivatives. MATERIAL AND METHOD: We synthesized some new hydrazones and then, the corresponding bishydrazones using salicylaldehyde. By condensing isatin and its derivatives (methyl-, nitro-, brom-) with hydrazine, corresponding hydrazones were obtained. The bishydrazones were synthesized by refluxing the obtained hydrazones with salicylaldehyde in methanolic solution. The structure of new compounds was confirmed by elemental and spectral analysis. The lipophilicity of the synthesized derivatives was expressed by clog P values. The antibacterial and antifungal activities of the compounds were determined using disk-diffusion method against Gram positive, Gram negative bacteria, and Candida albicans. RESULTS: New bishydrazines derived from isatin have been synthesized; their structures have been confirmed by elemental and spectral analysis. | lld:pubmed |
