In view of potential biological activities of small molecule polyamides, we synthesized some novel N-(2-aminoethyl)-1-benzyl-2- (alkylthio)-1H-imidazole-5-carboxamide (7a,b), and N-(2-(1-benzyl-2-(alkylthio) -1H-imidazole- 5-carboxamido) ethyl)-1-benzyl-2- (alkylthio)-1H-imidazole-5-carboxamides (8a,b) as antitumor agents. The antitumor activity of compounds 7a,b and 8a,b was studied at c...
