Synthesis and in-vitro anticancer activity of 3,5-bis(indolyl)-1,2,4-thiadiazoles
摘要:
A series of 3,5-bis(indolyl)-1,2,4-thiadiazoles were synthesized and evaluated for their cytotoxicity against selected human cancer cell lines. The reaction of indole-3-thiocarboxamide 3 with iodobenzene diacetate underwent oxidative dimerization to give 3,5-bis(indolyl)-1,2,4-thiadiazoles 4a-n. Among the synthesized bis(indoly)-1,2,4-thiadiazoles, the compound 4h with 4-chlorobenzyl and methoxy substituents showed the most potent activity. (C) 2011 Elsevier Ltd. All rights reserved.

A small library of arylthioamides 1-12 was easily synthesized, and their H2S-releasing properties were evaluated both in the absence or in the presence of an organic thiol such as L-cysteine. A number of arylthioamides (1-3 and 7) showed a slow and L-cysteine-dependent H2S-releasing mechanism, similar to that exhibited by the reference slow H2S-releasing agents, such as diallyl disulfide (DADS) and the phosphinodithioate derivative GYY 4137. Compound 1 strongly abolished the noradrenaline-induced vasoconstriction in isolated rat aortic rings and hyperpolarized the membranes of human vascular smooth muscle cells in a concentration-dependent fashion. Finally, a significant reduction of the systolic blood pressure of anesthetized normotensive rats was observed after its oral administration. Altogether these results highlighted the potential of arylthioamides 1-3 and 7 as H2S-donors for basic studies, and for the rational design/development of promising pharmacotherapeutic agents to treat cardiovascular diseases.
