title: New NO donors with antithrombotic and vasodilating activities, Part 29. N-(1-cyanocyclohexyl)-C-phenylnitrones and glyoxaldinitrones.
abstract: Six N-(1-cyanocyclohexyl)-C-phenylnitrones 4a-f (4b-f for the first time) and 22 glyoxaldinitrones 7a-v were prepared and tested for antithrombotic (p.o. administration to rats, 60 mg/kg) effects. Both classes of compounds exhibit considerable antithrombotic activities. Maximum inhibition of thrombus formation in arterioles (21%) was observed in N,N'-bis-2-phenylethylglyoxaldinitrone (7o) and N,N'-bis-4-nitrobenzylglyoxaldinitrone (7u). The compounds form only small amounts of nitric oxide in vitro by the addition of a Fe(3+)-porphyrine complex and an oxygen donor.
