ABSTRACT:
Novel 10-substituted steroids of the formula ##STR1## wherein R is selected from the group consisting of hydrogen, alkyl and substituted alkyl of 1 to 8 carbon atoms, alkenyl, substituted alkenyl, alkynyl and substituted alkynyl of 2 to 8 carbon atoms, aryl and substituted aryl, aralkyl and substituted aralkyl, protected hydroxy, optionally esterified carboxy, --NH.sub.2, protected amino, mono and di-alkyl amino of 1 to 4 alkyl carbon atoms, halogen and trialkylsilyl, R.sub.2 is methyl or ethyl, R.sub.6 and R.sub.7 together with the carbon atoms to which they are attached form cyclopropyl or R.sub.6 is hydrogen and R.sub.7 is R.sub.1, R.sub.1 is selected from the group consisting of hydrogen, alkyl and substituted alkyl of 1 to 6 carbon atoms, acetylthio and alkenyl, substituted alkenyl, alkynyl and substituted alkynyl of 2 to 6 carbon atoms, X is optionally acylated or etherified hydroxyl and Y is selected from the group consisting of hydrogen, R.sub.4, --CH.sub.2 --CH.sub.2 COOM and --CH.sub.2 --CH.sub.2 --CH.sub.2 OH, M is hydrogen, alkali metal or --NH.sub.4 or X and Y together form a member of the group consisting of ##STR2## or X is --OH and Y is ##STR3## R.sub.4 is selected from the group consisting of alkyl of 1 to 6 carbon atoms and alkenyl and alkynyl of 2 to 6 carbon atoms, Alk is alkyl of 1 to 8 carbon atoms, the dotted lines in the 1(2) and 6(7) indicate the optional presence of a second carbon-carbon bond with the proviso that when R.sub.6 and R.sub.7 form cyclopropyl, there is no 6(7) second bond, the dotted line in 10-substituent indicates the optional presence of a third carbon-carbon bond, the wavy lines at R.sub.6 and R.sub.7 indicate the possible .alpha.- or .beta.-position with the proviso that R is not hydrogen when R.sub.6 and R.sub.7 are hydrogen R.sub.2 is methyl, X is hydroxy or acetoxy and Y is hydrogen, the dotted lines at 1(2) and 6(7) do not represent a second bond and the dotted line in the 10-substituent is a third carbon-carbon bond useful as aldosterone antagonists and for increasing hydrosodium diuresis while preserving organic potassium with reduced hormonal side effects.
