Effect of perezone, aminoperezone and their corresponding isomers isoperezone and isoaminoperezone upon in vitro platelet aggregation.
The effect on platelet aggregation of perezone, isoperezone, aminoperezone and isoaminoperezone has been determined in human platelets, using adenosinediphosphate (ADP), epinephrine and collagen as inducers. Perezone inhibited ADP- epinephrine- and collagen-induced platelet aggregation; isoperezone, aminoperezone and isoaminoperezone did not. The difference in biological responses could be the result of their structures. While isoperezone, aminoperezone and isoaminoperezone have carbonyl groups in the vicinity of other functional groups, this is not the case for perezone, in which one of the carbonyl groups has an adjacent free position.
