derivatives, unknown up to now, is described. All compounds are alkyl or arylalkyl substituted in 3‐position of the sydnone imine. The most powerful agent was the 3‐propyl derivative 6c. It inhibits the aggregation of human platelets induced by collagen in a concentration of 1 γmol/L half maximally. Its N‐ethoxycarbonyl derivative 7c, which was designed as a prodrug, showed only small antithrombotic effects
