title: New NO-donors with antithrombotic and vasodilating activities, IX: Thiadiazole nitrosimines.
abstract: Twenty 1,3,4-thiadiazole-2-nitrosimines and two 1,2,4-thiadiazole-5-nitrosimines were synthesized and assayed in the Born-test for their antiplatelet activity. Only two 1,3,4-thiadiazoles inhibited the aggregation at IC50 < 10 mumol/L. In an in vivo thrombosis model only in arterioles a small inhibition of thrombus formation was observed. The poor test results correspond to a very high chemical stability of the titel nitrosimines.
