Tafluprost acid is a prostanoid selective FP receptor agonist that is believed to reduce the intraocular pressure (IOP) by increasing the outflow of aqueous humor. Studies in animals and humans suggest that the main mechanism of action is increased uveoscleral outflow. A prostaglandin analogue ester prodrug used topically (as eye drops) to control the progression of glaucoma and in the management of ocular hypertension. Tafluprost was approved for use in the U.S. on February 10, 2012. Tafluprost, preserved and preservative-free formulations, received marketing approval for the reduction of elevated intraocular pressure (IOP) in open-angle glaucoma and ocular hypertension in several European and Nordic countries as well as Japan, and some other Asia Pacific markets.

The affinity for the FP receptor shown by AFP-172 (Ki : 0.4 nm) was 12 times that of PhXA85 ( Ki : 4.7 nm), a carboxylic acid of latanoprost. For the prostanoid FP receptor-binding study, it was used a clonal cell line that stably expresses the recombinant human prostanoid FP receptor. The AFP-172 showed a high afﬁnity for the human prostanoid FP receptor, with an EC50 of 0,53 nM.
