Mercaptoacetyliminothiadiazoline derivatives (19, 20) useful for the pendant moiety of 1β-methylcarbapenem antibiotics were efficiently synthesized. Acetyl derivative (18) of 20 was submitted to X-ray analysis, and a significant nonbonded S…O close contact was recognized in the crystallographic structure. New 1β-methylcarbapenems (5, 6) were synthesized by exploiting 19 and 20, and exhibited considerable antibacterial activities in vitro.

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 μmol/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
