Ezlopitant
Ezlopitant (CJ-11,974) is a selective, non-peptidic neurokinin-1 (NK-1)-receptor antagonist. Ezlopitant inhibits both acute and delayed emetic reactions induced by Cisplatin (HY-17394) in ferrets via acting on NK1 receptors in the central nervous system. Ezlopitant has the potential for pain, chemotherapy-induced emesis and irritable bowel syndrome research.
