[Effect of 7-aza- and 13-aza-prostanoids on platelet aggregation].
The effects of 11 new analogues of 7-aza- and 13-azaprostanoic acid on platelet aggregation of the rat were studied in vitro and ex vivo. The analogues of 13-azaprostanoic acid in vitro (10(-7)-10(-8) mol/l) were found to exhibit the antiaggregation activity in the blood. The compounds containing five-member cycle are more active antiaggregants. They decrease by 70-80% the degree of platelet aggregation stimulated by thrombin and ADP. The modification of omega-chain of these analogues (alkyl, phenyl) exerts no effect on the antiaggregation activity. The antiaggregation action of these compounds in ex vivo condition (5-10 micrograms/kg) does not preserve. 7-azaprostanoids possess the proaggregation activity in vitro.
