Literature References: One of the most biologically studied of the primary prostaglandins. Closely related to prostaglandin E2 (PGE2) in that both prostaglandins are biosynthesized from the same precursors and that PGF2a is the synthetic reduction product of PGE2. For refs to synthesis of dl and natural forms see Prostaglandin E2. Prepn of the tromethamine salt: W. Morozowich, DE 2126127; idem, US 3657327 (1971, 1972 both to Upjohn). Alternate synthesis of natural PGF2a: Schneider, Murray, J. Org. Chem. 38, 397 (1973); R. B. Woodward et al., J. Am. Chem. Soc. 95, 6853 (1973); G. Stork et al., ibid. 100, 8272 (1978); K. Kondo et al., Tetrahedron Lett. 1978, 3927; N. R. A. Beeley et al., Tetrahedron 37, Suppl. 9, 411 (1981); R. J. Cave et al., J. Chem. Soc. Perkin Trans. 1 1981, 646. Causes vasocontraction and exhibits luteolytic activity; is most commonly associated with its role in pregnancy: Karim et al., J. Obstet. Gynaecol. Brit. Commonw. 78, 172 (1971). Metabolism in female subjects: Granstrom, Samuelsson, J. Biol. Chem. 246, 5254 (1971). Toxicity data: T. Fujita et al., Iyakuhin Kenkyu 9, 261 (1978), C.A. 89, 71399k (1978).
