Synthesis
Progestin, pregn-4-en-3,20-dione (28.3.1), is made by oxidizing pregnenolon with aluminum isopropylate in the presence of cyclohexanone as a proton acceptor (Oppenauer oxidation). Progestin itself is made by subsequent oxidation and further cleavage of the side chain of stigmasterin, a sterin of plant origin that is isolated from soybeans.
Physiological effects
Progestin is believed to act by inducing decidualization and atrophy of the endometrial tissue within endometriotic implants. Progestin also interfere with follicular growth probably via a central mechanism on the pituitary–hypothalamic unit, but a local ovarian effect is also possible. This will result in decreased estrogen levels.
