Abstract
The effects of PGG2 and PGH2 on platelets are mimicked by synthetic PG analogues in which the nature and specificity of the substituents on carbons 11 and 15 (or 16) are important determinants of reactivity. Arachidonic acid and stimulatory PGs induce secretion of platelet dense granule and alpha granule constituents, but not lysomal constituents, although arachidonate metabolism is necessary for collagen-induced release of lysosomal enzymes. NO164 acts on platelets as an endoperoxide antagonist: Trimethoquinol acts as an endoperoxide and TxA2 antagonist. PGs induce platelet aggregation by combining with a specific (endoperoxide) receptor.
