Selective androgen receptor modulators based on a series of 7H-[1,4]oxazino[3,2-g]quinolin-7-ones with improved in vivo activity

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 3 mg/kg and reduced activity on ventral prostate weight in a 2-week orally-dosed and orchidectomized rat maintenance assay.

The synthesis and biological evaluation of a selective androgen receptor modulator (SARM) with improved in vivo activity is reported.Figure optionsDownload as PowerPoint slide
