A series of ω-(1-substituted-5-tetrazolylalkoxy)-2-oxoquinolines was synthesized and tested for inhibitory activity towards collagen-and adenosine diphosphate (ADP)-induced aggregation of rabbit blood platelets in vitro. These compounds were prepared by the reaction of 1-substituted-5-(ω-chloroalkyl)-tetrazoles and hydroxy-2-oxoquinolines in the presence of a base. Among them, 6-[3-(1-cyclohexyl-5-tetrazolyl)propoxy]-1, 2-dihydro-2-oxoquinoline (IVb) was found to have the most potent inhibitory activity. The structure-activity relationships are discussed.
