17-phenyl trinor Prostaglandin F2α-d4 (17-phenyl trinor PGF2α-d4) contains four deuterium atoms at the 3, 3', 4, and 4' positions. It is intended for use as an internal standard for the quantification of 17-phenyl trinor PGF2α by GC- or LC-mass spectrometry. 17-phenyl trinor PGF2α is a metabolically stable analog of PGF2α and is a potent agonist for the FP receptor. It binds to the FP receptor on ovine luteal cells with a relative potency of 756% compared to that of PGF2α.1 At the rat recombinant FP receptor expressed in CHO cells 17-phenyl trinor PGF2α inhibits PGF2α binding with a Ki of 1.1 nM.2 The isopropyl ester of 17-phenyl trinor PGF2α-d4 is slightly better than PGF2α isopropyl ester in reducing the intraocular pressure in the cat eye without any irritation.3
