Diarylsemicarbazones: synthesis, antineoplastic activity and topoisomerase I inhibition assay
摘要:
A series of diarylsemicarbazones was synthesized and tested against human neoplastic cell lines. The more active members have a 1-naphthyl ring at the carbamidic nitrogen, and chloro, dimethylamino or nitro group substituents at the benzylidene moiety. None of these showed affinity to DNA. One of the more active compounds was tested as a topoisomerase I inhibitor and showed a potent effect. SAR studies demonstrated linear correlation between lypophilicity and activity on the most sensitive lines and a definite conformational shape for antineoplastic action.

A convenient, one-pot synthesis of N-isatinylmethylthioacetic acid and several of its derivatives, as potential anticancer agents, by reactions of N-(hydroxymethyl)isatins with Bunte salts in TFA is described. The reactions involve attack of these salts on the S(II) atom by C-electrophilic species generated from hydroxy derivatives.
