title: [An 11-fluoroderivative of prostaglandin F2alpha--a stable thromboxano-mimetic].
abstract: In a search for stable thromboxanomimetics the action of 11-fluoro-11-deoxyprostaglandin F2 alpha (11-fluoro-PGF2 alpha) on the aggregatory properties of platelets and the tone of the vascular, respiratory and gastrointestinal smooth muscles was studied. It was found that 11-fluoro-PGF2 alpha, in contrast to PGF2 alpha, induces platelet aggregation and exhibits a high activity with respect to smooth muscles sensitive to thromboxane A2 alpha (TXA2) and a low activity for smooth muscles sensitive to PGF2 alpha 9-11-epoxyimino-PGH2 (a specific antagonist of TXA2 receptors) competitively blocked the action of 11-fluoro-PGF2 alpha on vascular smooth muscles. Thus, 11-fluoro-PGF2 exhibits properties of a thromboxanomimetic that makes it possible to propose it for modelling TXA2-induced biological effects.
