15-deoxy-δ^12,14-PGJ₂-d₄contains four deuterium atoms at the 3, 3', 4, and 4' positions. It is intended for use as an internal standard for the quantification of 15-deoxy-δ^12,14-PGJ₂by GC-or LC-mass spectrometry. 15-deoxy-δ^12,14-Prostaglandin J₂(15-deoxy-δ^12,14-PGJ₂) is a metabolite of PGJ₂. 15-deoxy-δ^12,14-PGJ₂is formed from PGD₂by the elimination of two molecules of water. It binds selectively to PPARγ with an EC₅₀of 2 µM in a murine chimera system.^1,215-deoxy-δ^12,14-PGJ₂is more potent than PGD₂, δ¹²-PGJ₂, and PGJ₂in stimulating lipogenesis in C3H10T1/2 cells. The EC₅₀for induction of adipocyte differentiation in cultured fibroblasts is 7 µM.¹
