Potential antitumor agents. Part 29(1): synthesis and potential coanthracyclinic activity of imidazo(2,1-b)thiazole guanylhydrazones.

摘要

This paper reports the synthesis of new imidazo[2,1-b]thiazole guanylhydrazones which were tested as potential antitumor agents. Three of these derivatives (those bearing a 3- or 4-nitrophenyl group) were the most potent and one of these showed a mild effect as CDK1 inhibitor. These same three derivatives were also tested as positive inotropic agents and two of them were more potent than amrinone at 10(-5) M. These two guanylhydrazones could be useful coanthracyclinic agents.
