Synthesis and evaluation of anti-HIV activity of isatin β-thiosemicarbazone derivatives
摘要:
On the basis of pharmacophoric modelling studies of existing NNRTIs, a series of isatin beta-thiosemicarbazonc derivatives was synthesized and evaluated for their anti-HIV activity in HTLV-IIIB strain in the CEM cell line. Three compounds showed significant anti-HIV activity, whereupon compound 6 was found to be the most active compound with an EC50 value of 2.62 mu M and a selectivity index of 17.41, while not being cytotoxic to the cell line at a CC50 value of 44.90 mu M. Other tested compounds exhibited marked activity below their toxicity threshold. (c) 2005 Elsevier Ltd. All rights reserved.

A series of N(4)-substituted thiosemicarbazones of isatin were synthesized and their copper(II) complexes prepared from copper(II) chloride. X-ray crystal structures of two of the thiosemicarbazones, isatin 3-(hexamethylenimylthiosemicarbazone) and isatin 3-(N(4)-ethylthiosemicarbazone), have been solved and are compared with a previously published structure of isatin 3-(N(4)-p-tolythiosemicarbazone). The coordination chemistry of the copper(II) complexes of these and other isatin thiosemicarbazones is reported and discussed. Copyright (C) 1996 Elsevier Science Ltd
