We have recently discovered 5-(3-cyclopentyl-2-thioxo-2,3-dihydro-1H-benzimidazol-5-yl)-1-methyl-1H-pyrrole-2-carbonitrile (14) as a potent, selective, and orally active non-steroidal progesterone receptor (PR) agonist. Compound 14 and its analog 13 possessed sub-nanomolar in vitro potency (EC(50) 0.1-0.5nM) in the T47D alkaline phosphatase assay, similar to that of the steroidal PR agonist medroxyprogesterone acetate (MPA). In contrast to MPA, 14 was highly selective (>500-fold) for the PR over both glucocorticoid and androgen receptors. In the rat uterine decidualization and complement component C3 models, 14 had oral ED(50) values of 0.02 and 0.003mg/kg, respectively, and was from 6- to 20-fold more potent than MPA. In the monkey ovulation inhibition model, compound 14 was also highly efficacious and potent with an oral ED(100) of 0.03mg/kg.

Non-steroidal 1-methyl-1H-pyrrole-2-carbonitrile containing tetrahydronaphthalenes and acyclic derivatives were evaluated as novel series of progesterone receptor (PR) antagonists using the T47D cell alkaline phosphatase assay. Moderate to potent PR antagonists were achieved with these scaffolds. Several compounds (e.g., 15 and 20) demonstrated low nanomolar PR antagonist potency and good selectivity versus other steroid receptors.
