3-(2-Aminoalkyl)-1-(2,6-difluorobenzyl)-5- (2-fluoro-3-methoxyphenyl)-6-methyl- uracils as Orally Bioavailable Antagonists of the Human Gonadotropin Releasing Hormone Receptor

Abstract

Uracils possessing N-3 side chains derived from various amino alcohols were designed and synthesized as potent human gonadotropin releasing hormone receptor antagonists. The compounds herein presented displayed superior metabolic stability than their predecessor molecules. Selected compounds from this series featured good oral bioavailability in mice and cynomolgus monkeys.
