11β-Prostaglandin F
2α-d
9 (11β-PGF
2α-d
9) is intended for use as an internal standard for the quantification of 11β-PGF
2α by GC- or LC-MS. 11β-PGF
2α is the primary metabolite of PGD
2 .
1 It is formed from PGD
2 via the NADPH-dependent aldo-keto reductase PGF synthase (PGFS; ） in the liver or lung.
2 11β-PGF
2α induces contraction of isolated cat iris sphincter, which endogenously expresses high levels of PGF
2α (FP) receptors, with an EC
50 value of 0.045 μM.
1 It also induces contraction of isolated human bronchial smooth muscle when used at concentrations ranging from 0.1 to 30 μM.
3 11β-PGF
2α (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.
