The lactame-triazole or lactame-tetrazole isostery applied to the quinolinone lactames of compound Y-590 or cilostazole lead to compounds which show similar potencies on platelet specific phosphodiesterase inhibition, platelet aggregation inhibition and antithrombotic effects. On the other hand a supplementary isostery of the same type applied to the pyridazinone carbonyl group of compound Y-590 resulted in a dramatic loss of activity illustrating the importance of the pyridazinone moiety for the observed effects. However, this lactame carbonyl group can be replaced by an amidine or a thioamide group with retention of the activities.
