Progesterone derivatives of the formula
wherein Y is hydrogen or hydroxy; Z is hydrogen or hydroxy; and R is 1,2-propadienyl, 2-alkynyl containing up to 6 carbon atoms, or 1-hydroxy-2-propynyl. The compounds are useful as aldosterone inhibitors.
Cytochrome P-450(11 beta) is a key enzyme in the biosynthesis of aldosterone which catalyzes the transformation of 11--deoxycorticosterone (DOC) to aldosterone via three successive hydroxylations (at C-11 and at C-18). This enzyme is irreversibly inactivated by 18-VP 1 and 18-EP 4. In order to determine the mechanism of the inactivation, we have synthesized three potential reactive enzyme-generated intermediates 2, 3 and 5.

Progesterone derivatives having a vinylidene or a 1-alkynyl substituent at the 18-position and further optionally hydroxylated at the 11-position and the 21-position are described herein. Compounds having both an ethynyl substituent and a hydroxy substituent at the 18-position are also described herein. The compounds are useful as aldosterone inhibitors.
