摘要
New isatin-triazole based hybrids have been synthesized and evaluated for their inhibitory activity of TNF-alpha induced expression of Intercellular Adhesion Molecule-1 (ICAM-1) on the surface of human endothelial cells. Structure-activity relationship (SAR) studies revealed that the presence of the electron-attracting bromo substituent at position-5 of the isatin moiety played an important role in enhancing the anti-inflammatory potential of the synthesized compounds. Z-1-[3-(1H-1,2,4-Triazol-1-yl) propyl]-5-bromo-3-[2-(4-methoxyphenyl)-hydrazono]indolin-2-one (19) with an IC50 = 20 mu M and 89% ICAM-1 inhibition with MTD at 200 mu M was found to be the most potent of all the synthesized derivatives. Introduction of 1,2,4-triazole ring and electron-donating methoxy group on the phenylhydrazone moiety resulted in four-fold increase of the anti-inflammatory activity.
