aggregation induced by collagen (Born‐test). Five compounds exhibit this activity in concentrations below 10 μmol/L (IC50). This is due to the release of a NO species, as could be demonstrated by the stimulation of soluble guanylate cyclase in a cell free system (e.g. 8a, KM = 72 μmol/L). In vivo the nitrosimines show antithrombotic properties. Two h after a single oral dose of 8g (60 mg/kg) a 57% inhibition
New NO-Donors with Antithrombotic and Vasodilating Activities, IV: Chemical Reactivity of Nitrosimines and its Implications for their Pharmacologic Properties
Nitrososydnone‐5‐imines and Thiazole‐2‐nitrosimines are susceptible to photolytic cleavage of the NNO bond. This can be achieved with a tungsten lamp. In water the corresponding syndnone imine salts are formed in 90% yield at 37°C. Only at higher temp. (70°C) ring opening is observed. In methanol about 25% of sydnones are obtained. On the other hand NO⋅ and N2O were detected in the head space of
