rac-Aprepitant-d4 is intended for use as an internal standard for the quantification of aprepitant by GC- or LC-MS. Aprepitant an antiemetic compound and antagonist of the neurokinin-1 (NK1) receptor (Ki = 3 nM; IC50 = 0.09 nM for the human receptor).1,2 It is selective for NK1 over NK3 receptors (Ki = 454.1 nM for human NK3).1 In vivo, aprepitant (1 mg/kg) prevents plasma extravasation into the esophagus of guinea pigs induced by substance P .3 It also reduces NK1-agonist-induced foot tapping in gerbils. Formulations containing aprepitant have been used to prevent chemotherapy-induced nausea and vomiting.
