Discovery of highly selective EP4 receptor agonists that stimulate new bone formation and restore bone mass in ovariectomized rats

Bioorg Med Chem Lett. 2006 Apr 1;16(7):1799-802. doi: 10.1016/j.bmcl.2006.01.018. Epub 2006 Jan 26.

Abstract

Heptanoic acid lactams, exemplified by 2, were identified as highly selective EP4 agonists via high throughput screening. Lead optimization led to the identification of lactams with a 30-fold increase in EP4 potency in vitro. Compounds demonstrated robust bone anabolic effects when administered in vivo in rat models of osteoporosis.
