Solid

IC50: 8.9 nM (rat uterus oxytocin receptor), 26 nM (human uterus oxytocin receptor)

L-368,899 hydrochloride is a potent, orally bioavailable, non-peptide oxytocin receptor antagonist, with IC50s of 8.9 nM and 26 nM for rat uterus and human uterus oxytocin receptor, respectively. L-368,899 is less active on VP receptor in human liver and kidney, rat liver and kidney (IC50, 510 nM, 960 nM, 890 nM, 2400 nM, respectively). has not independently confirmed the accuracy of these methods. They are for reference only.

L-368,899 exhibits similar pharmacokinetics in rats and dogs. After a single iv. injection, L-368,899 had a t 1/2 of 2 hr in both species. Additionally, L-368,899 has a plasma clearance between 23 and 36 ml/min/kg in rats or dogs. L-368,899 exhibits V dss values of 2.0 and 2.6 liters/kg and 3.4 to 4.9 liters/kg for dogs, respectively.
L-368,899 is orally available. In the rat, at the 5 mg/kg dose, the oral bioavailabilities are 14% and 18% for female and male rats, respectively. Additionally, the oral bioavailabilities are 17% and 41% for female and male rats, respectively at the dosage of 25 mg/kg. has not independently confirmed the accuracy of these methods. They are for reference only.
