16-Methylene-17α-hydroxy-19-norpregn-4-ene-3,20-dione 1 and its 17α-acylated derivatives were synthesized. The length of the 17α-side-chain ranges from C 2 -C 6 . As anticipated, compound 1 did not show any progestational activity or receptor binding activity; whereas, the acylated compounds, especially the butyrate, showed remarkable ability to bind to progesterone receptors. These...
The stability of the contraceptive steroid, Nestorone (16-methylene-17α-acetoxy-19-nor-pregn-4-ene-3,20-dione) in the solid state and in aqueous solutions, was investigated using reverse-phase high-performance liquid chromatography. In the solid state, whether as a powder or when it is incorporated into Silastic implants, the steroid does not undergo detectable degradation even under severe experimental...
