Novel 7-aryl benzo[1,4]oxazepin-2-ones were synthesized and evaluated as non-steroidal progesterone receptor (PR) modulators. The structure activity relationship of 7-aryl benzo[1,4]oxazepinones was examined using the T47D cell alkaline phosphatase assay. A number of 7-aryl benzo[1,4]oxazepinones such as 10j and 10v demonstrated good in vitro potency (IC50 of 10-30 nM) and selectivity (over 100-fold) at PR over other steroidal receptors such as glucocorticoid and androgen receptors (GR and AR). Several 7-aryl benzo[1,4]oxazepinones were active in the rat uterine decidualization model. In this in vivo model, compounds 10j and 10u were active at 3 mg/kg when dosed orally.

A series of novel 7-(5′-cyanopyrrol-2-yl) substituted benzo[1,4]oxazepin-2-ones were prepared and tested for their progesterone receptor (PR) agonist or antagonist activity in the alkaline phosphatase assay using the human T47D breast carcinoma cell line.
Synthesis and structure-activity relationship of novel 6-aryl-1,4- dihydrobenzo[d][1,3]oxazine-2-thiones as progesterone receptor modulators leading to the potent and selective nonsteroidal progesterone receptor agonist tanaproget

Tanaproget represents a potential first-in-class nonsteroidal PR agonist for contraception with improved safety and side effect profiles versus currently available steroidal oral contraceptives. Additional SAR, biological activity, and structural information from a tanaproget/hPR-LBD (hPR-LBD = human progesterone receptor ligand binding domain) cocrystal structure will also be presented.
