MedKoo Cat#: 414640 | Name: Osanetant HCl

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Osanetant (SR142801) is a potent and selective non-peptide antagonist of the tachykinin NK3 receptor. It exhibits high affinity with a Ki of about 1.1–3.6 nM for the human NK3 receptor and shows over 500-fold selectivity versus NK1 and NK2 receptors. In preclinical studies, osanetant effectively blocks NK3 receptor-mediated responses, such as neurokinin B-induced contractions and hormone release. For example, it has been shown to inhibit NK3 receptor agonist–induced LH release in rodents and primates.
