prostaglandin a-2

PGA2 is a naturally occurring prostaglandin in gorgonian corals where it may function in self defense. It is generally not present in mammals. PGA2 has low biological potency in most bioassays, but it does show some antiviral antitumor activity.[1] At a 25 uM concentration, PGA2 blocks the cell cycle progression of NIH 3T3 cells at the G1 and G2 M phase .[2] It has also been shown to act as a vasodilator with natriuretic properties.[3]

16,16-dimethyl PGA2 is a metabolism-resistant analog of PGA2 with a prolonged in vivo half-life. It inhibits the proliferation of Sendai virus in cultured African green monkey kidney cells by >90% at a concentration of 4 μg ml. Daily infusion of 10 μg of 16,16-dimethyl PGA2 methyl ester into mice infected with influenza A virus increased survival by 40%. Similar treatment of mice inoculated with erythroleukemia cells delayed tumor growth and increased survival time.

Arbaprostil, a synthetic analog of prostaglandin E2 (PGE2) known as 15(R)-15-methyl prostaglandin E2, was developed for its cytoprotective activity. In the commercial production of bulk arbaprostil, one potential impurity is 15(R)-15-methyl Prostaglandin A2 (15(R)-15-methyl PGA2). The pharmacology and EP receptor binding affinity of 15(R)-15-methyl PGA2 have not been reported.
