Rolapitant hydrochloride

Research use only, not for human use.

Rolapitant Hydrochloride is the hydrochloride salt form of rolapitant, an orally bioavailable, centrally-acting, selective, neurokinin 1 receptor (NK1-receptor) antagonist with potential antiemetic activity.

Rolapitant Hydrochloride is the hydrochloride salt form of rolapitant, an orally bioavailable, centrally-acting, selective, neurokinin 1 receptor (NK1-receptor) antagonist with potential antiemetic activity.(In Vitro):Rolapitant has high selectivity over the human NK2 and NK3 subtypes of more than 1000-fold, as well as preferential affinity for human, guinea pig, gerbil and monkey NK1 receptors over rat, mouse and rabbit.Rolapitant (1-1000 nM) inhibits the GR-73632 (an NK1 receptor agonist)-induced calcium efflux with a concentration-dependent and competitive manner in CHO cells expressing the human NK1 receptor.(In Vivo):Rolapitant (0.03-1 mg/kg for PO, 0.3-1 mg/kg for IV; single dosage) attenuates the GR-73632-induced foot-tapping response in Mongolian Gerbils.Rolapitant (0.03-1 mg/kg; PO; single dosage; observed for 72 h) blocks acute emesis induced by both apomorphine and cisplatin in ferrets.

Animal Model:Female Mongolian Gerbils (30-60 g; anesthetized by inhalation of an oxygen:isofluorane mixture after 4 h PO or immediately after IV, then injected with 5 μl of 3 pmol solution of GR-73632 via ICV)Dosage:0.03, 0.1, 0.3 and 1 mg/kg for PO, 0.3 and 1 mg/kg for IVAdministration:PO or IV, single dosageResult:Attenuated dose-dependently the GR-73632-induced foot-tapping response when administered PO 4 h before testing, with an ID90 of 0.3 mg/kg, and the inhibition in foot tapping for at least 24 h.Blocked dose-dependently the foot tapping induced by GR-73632 when administered IV, with complete blockade observed at 1 mg/kg.Animal Model:Ferrets (treated with subcutaneous administration of 0.125 mg/kg apomorphine or intraperitoneal administration of 10 mg/kg cisplatin)Dosage:0.03, 0.1, 0.3 and 1 mg/kg Administration:PO; single dosage; observed for 72 h Result:Blocked dose-dependently acute emesis induced by both apomorphine and cisplatin in ferrets.Produced a robust decrease in retches and vomits in ferrets that was maintained throughout the 72 h observation period.
