Synthesis and biological activity of 9-deoxo-9-methylene and related prostaglandins
Abstract:
A number of PGE analogs have been synthesized in which the C-9 carbonyl group has been replaced by an exo-methylene group. These chemically stable 9-deoxo-9-methylene-PGEs exhibit biological profiles very similar to their less stable PGE relatives. 9-Deoxo-16,16-dimethyl-9-methylene-PGE2 (7) retains the useful uterine-stimulating potency of 16,16-dimethyl-PGE2 but is approximately 300 times less enteropooling in the rat. In preliminary clinical trials, 7 has shown efficacy for pregnancy termination by the oral and vaginal routes of administration, as well as relative freedom from gastrointestinal side effects.

Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...

Phase II Reactions: Methylation Reactions
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...
