Syntheses and antitumor activities of N′1,N′3-dialkyl-N′1,N′3-di-(alkylcarbonothioyl) malonohydrazide: The discovery of elesclomol
摘要:
A series of N'(1),N'(3)-dialkyl-N'(1),N'(3)-di(alkylcarbonothioyl) malonohydrazides have been designed and synthesized as anticancer agents by targeting oxidative stress and Hsp70 induction. Structure-activity relationship (SAR) studies lead to the discovery of STA-4783 (elesclomol), a novel small molecule that has been evaluated in a number of clinical trials as an anticancer agent in combination with Taxol.

N,N′-Diacyl acid dihydrazides were prepaed by the reaction of acid dihydazides with two equivalents of acyl chlorides. The structures of these compounds were elucidated by 1H and 13C NMR spectroscopy.
