Kallander L, Washburn D, Hoang T, Frazee J, Stoy P, Johnson L, et al.
Bioorg Med Chem Lett . 2009 Nov; 20(1):371-4. PMID: 19926282
The previously reported pyrrolidine class of progesterone receptor partial agonists demonstrated excellent potency but suffered from serious liabilities including hERG blockade and high volume of distribution in the rat. The...

Washburn D, Hoang T, Frazee J, Johnson L, Hammond M, Manns S, et al.
Bioorg Med Chem Lett . 2009 Jul; 19(16):4664-8. PMID: 19616429
We have designed and synthesized a novel series of pyrrolidinones as progesterone receptor partial agonists. Compounds from this series had improved AR selectivity, rat pharmacokinetic properties, and in vivo potency...
