title: [Changes in the cyclic nucleotide level and the inhibition of human thrombocyte aggregation in 3-hydroxypyridine exposure].
abstract: The effect of six 3-oxypiridine derivatives (at a concentration of 10(-3) and 5 X 10(-3) M) on cyclic nucleotide level in human platelets and platelet aggregation was studied. Five 3-oxypiridine derivatives were shown to depress platelet aggregation, four of them causing the increase in cAMP platelet level. The correlation between antiaggregation activity of 3-oxypiridine derivatives and their ability to rise cyclic nucleotide level in human platelets is discussed.
