Fluprostenol-d4

Fluprostenol-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 fluprostenol by GC- or LC-mass spectrometry. Fluprostenol is a metabolically stable analog of prostaglandin F_2α (PGF_2α) with potent FP receptor agonist activity.1^1,2 It inhibits PGF_2α binding to human and rat FP receptors with IC₅₀ values of 3.5 and 7.5 nM, respectively.^1,2 Fluprostenol is a much more potent luteolytic agent than PGF_2α in rats with a minimum fully effective dose of 270 . g/kg to terminate pregnancy.³ It is also an effective inhibitor of rat adipose precursor differentiation in primary cultures with an IC₅₀ value of 3-10 x 10^-11 M.⁴
