ABSTRACT:
The present invention relates to novel estrogen-related steroidal quinols and their use as prodrugs for phenolic estrogens and estrogen analogs. The quinols of the present invention provide improved physicochemical properties, increased bioavailability, and improved distribution into tissues and penetration across the blood-brain barrier when compared to phenolic estrogens and estrogen analogs.
