This paper reports the synthesis of imidazo[2,1-b]thiazoles, bearing a dihydropyridine ring at the 5 or 6 position, which were tested for antiarrhythmic, inotropic and chronotropic activities. Nine of the ten compounds bearing double bond at the 2,3 position and the same dihydropyridine as nifedipine at the 5 position, were antiarrhythmic; moreover one of them (bearing a methyl group at the 2 position) was devoid of negative inotropic activity.

Potential antitumor agents. part 291: synthesis and potential coanthracyclinic activity of Imidazo[2,1-b]thiazole guanylhydrazones
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
