Abstract
Novel antiandrogenic agents are provided. An exemplary group of compounds has the structural formula (I) ##STR1## wherein R.sup.1 through R.sup.10, a and b are as defined herein. Pharmaceutical compositions and methods for using the compounds of formula (I) to treat androgen-related clinical conditions are provided, as are methods and compositions for using the compounds as contraceptive agents.
Claims22
A compound having the structural formula ##STR14## wherein:
- R.sup.1 and R.sup.2 are independently selected from the group consisting of hydrogen and lower alkyl;
- and
- one of R.sup.6 and R.sup.7 is hydroxyl and the other is n-propyl, or R.sup.6 and R.sup.7 are linked to provide a cycloalkyl group containing 3 to 6 carbon atoms.
A pharmaceutical composition comprising, in combination with a pharmaceutically acceptable carrier, an amount of a compound having the structural formula ##STR16## wherein:
- R.sup.1 and R.sup.2 are independently selected from the group consisting of hydrogen and lower alkyl;
- and
- one of R.sup.6 and R.sup.7 is hydroxyl and the other is n-propyl, or R.sup.6 and R.sup.7 are linked to provide a cycloalkyl group containing 3 to 6 carbon atoms.
A compound having the structural formula ##STR18## wherein:
- R.sup.5 is hydrogen or lower alkyl;
- and
- R.sup.6 and R.sup.7 are linked to provide a cycloalkyl or cyclooxyalkyl ring containing 3 to 6 carbon atoms.
A pharmaceutical composition comprising, in combination with a pharmaceutically acceptable carrier, an amount of a compound having the structural formula ##STR20## wherein:
- R.sup.5 is hydrogen or lower alkyl;
- and
- R.sup.6 and R.sup.7 are linked to provide a cycloalkyl or cyclooxyalkyl ring containing 3 to 6 carbon atoms.
