Synthesis, conformational analysis and antitumor testing of 5-(Z)-arylidene-4-imidazolidinone derivatives

A series of 5-(Z)-arylidene-2-amino-4-imidazolidinones 16-34, 5-(Z)-arylidene-2-(2-carboxyphenylamino)-4-imidazolidinones 35-41, 5-(Z)-arylidene-3-aminomethyl-2-thioxo-4-imidazolidinones 42-55 and 5-(Z)-arylidene-3-aminomethyl-2-methylmercapto-4-imidazolidinones 56-67 have been synthesized via two different routes. Conformational analysis and antitumor activities have been studied. The antitumor activity of these compounds showed broad spectrum of activity against a wide range of different human cell lines of nine tumor subpanels causing both cytostatic and cytotoxic potency.
