11β-Prostaglandin F2α-d9 (11β-PGF2α-d9) is intended for use as an internal standard for the quantification of 11β-PGF2α (Item No. 16520) by GC- or LC-MS. 11β-PGF2α is the primary metabolite of PGD2 (Item No. 12010).{57057} It is formed from PGD2 via the NADPH-dependent aldo-keto reductase PGF synthase (PGFS; Item No. 10007940) in the liver or lung.{57058} 11β-PGF2α induces contraction of isolated cat iris sphincter, which endogenously expresses high levels of PGF2α (FP) receptors, with an EC50 value of 0.045 µM.{57057} It also induces contraction of isolated human bronchial smooth muscle when used at concentrations ranging from 0.1 to 30 µM.{1756} 11β-PGF2α (0.1 and 1 µM) induces phosphorylation of ERK and CREB, as well as increases the viability of MCF-7 breast cancer cells stably expressing the FP receptor when used at concentrations of 0.1 and 1 µM.{57059}
