Tafluprost acid

Tafluprost acid (AFP-172), an active metabolic form of Tafluprost, is a selective prostanoid FP receptor agonist. Tafluprost acid shows a high affinity for human prostanoid FP receptor with Ki and EC50 values of 0.4 nM and 0.53 nM, respectively. Tafluprost acid has 126 times weaker binding affinity for prostanoid EP3 receptor (IC50=67 nM) than for the prostanoid FP receptor. Tafluprost acid can be used in the research of glaucoma[1][2][3].

Tafluprost acid (10, 100 nM, added on days 0 and 2) significantly inhibits adipogenesis in the early and late stages of differentiation of 3T3-L1 preadipocytes[2]. Tafluprost acid (100 nM, added on day 2 after initiating differentiation) suppresses adipogenesis in wild-type but not in FP knockout mouse primary adipocytes[2]. Tafluprost acid (10-4 M, 6 hours) stimulates the proliferation, migration of human umbilical vascular endothelial cells (HUVECs)[4]. Tafluprost acid (10-4 M, 4-18 hours) stimulates the tube formation of HUVECs[4].
