Synthesis and cytostatic evaluation of some 2-(5-substituted-2-oxoindolin-3-ylidene)-N-substituted hydrazine carbothioamide
摘要:
Various substituted 2-(5-substituted-2-oxoindolin-3-ylidene)-N-substituted hydrazine carbothioamide 4a-g and 2-(5-substituted-1-(4-substituted benzyl)-2-oxoindolin-3-ylidene)-N-substituted hydrazine carbothioamide 5a-k were synthesized. The compounds were evaluated for their cytostatic activity against human Molt4/C8 and CEM T-lymphocytes as well as murine L1210 leukemia cells. Several of these compounds were endowed with low micromolar 50%-inhibitory concentration (IC50) values, and some were virtually equally potent as melphalan. The most potent inhibitors against the murine leukemia cells were also most inhibitory against human T-lymphocyte tumor cells. 2-(5-fluoro-1-(4-fluorobenzyl)-2-oxoindolin-3-ylidene)-N-p-tolylhydrazine carbothioamide (5b) emerged as the most potent cytostatic compound among the tested compounds. The encouraging cytostatic data provide an adequate rationale for further modification of these molecular scaffolds.

A series of isatin‐β‐thiosemicarbazones and isatin‐β‐hydrazonothiazolines was synthesized by condensation of various isatin derivatives with N4‐substituted 3‐thiosemicarbazides and cyclization of the products by phenacyl bromides. The products showed high toxicity at lower concentrations when tested for antiviral activity against MDCK cells and did not exhibit antimicrobial activity against various
