RESUMO
The 9,11-azo-prostanoid III [(5Z, 9alpha, 11alpha, 13E, 15S)-9, 11-azo-15-hydroxyprosta-5,13-dienoic acid] has been obtained by synthesis and tested for biological activity in systems which are responsive to the prostaglandin endoperoxides PGH2 (I) and PGG2 (II). The azo analog III is a powerful mimic of these endoperoxides with reference to platelet aggregation and release of serotonin when added to human platelet-rich plasma. The analog III is substantially more active (about 7 fold) than PGG2 in stimulating muscle contraction in the isolated rabbit aorta strip. The very great stability of III relative to PGH2 and PGG2 and its potency as a mimic of these important substances suggest that this azo analog will be of considerable value in future studies of the prostaglandin endoperoxides.
