Pregn-4-ene-3,20-dione. C 21 H 30 O 2 (314.46). One of the luteal hormones. Progesterone is the only luteal hormone secreted by the body. In 1934, it was independently isolated from pig ovaries by four research groups, including A. Butenandt, KH Slotta, WM Allen, and M. Hartmann. It is synthesized in large quantities from raw materials such as stigmasterol, diosgenin, and ergosterol, and is important as a raw material for the synthesis of adrenal cortical hormones. White crystals or crystalline powder. It is a crystalline polymorph with a melting point of 128-133 °C or 120-122 °C, and the lower melting point is unstable and easily changes to the higher melting point. +174 to +182° (dioxane). λ max 240 nm. Practically insoluble in water, but soluble in ethanol, acetone, chloroform, benzene, and dioxane. Adrenal cortical hormones, male hormones, and estrus hormones are all synthesized starting from progesterone. It is used to treat threatened miscarriage, habitual miscarriage, infertility due to implantation failure, irregular uterine bleeding, amenorrhea, and menstrual pain.
