L-368,899 is a potent and selective oxytocin (OT) receptor antagonist, which was developed by Merc as a promising non peptide OT antagonist. However, this compound failed in clinical development; phase II, for the treatment of premature labour. Merck subsequently abandoned its non peptide OT antagonist program.

In Vitro Use Guide

L-368,899 is a potent and competitive oxytocin (OT) receptor antagonist in the rat isolated uterus (pA2, 8.9) and mouse anococcygeus muscle (pA2, 8.3) and is inactive against a number of different contractile agents in these preparations. L-368,899 also inhibits OT-stimulated phosphatidylinositol turnover in rat uterine slices and exhibits no agonist-like activity in any of the in vitro assays.
