Abstract

Modification on a lead series of [1,4]oxazino[3,2-g]quinolin-7-ones at the 2-position led to selective Androgen Receptor modulators with improved in vivo activity. The most potent analog (-)-33a exhibited full maintenance of levator ani muscle at 3mg/kg and reduced activity on ventral prostate weight in a 2-week orally-dosed and orchidectomized rat maintenance assay.
