Aprepitant
5-[[(2R,3S)-2-[(1R)-1-[3,5-Bis(trifluoromethyl)phenyl]ethoxy]-3-(4-fluorophenyl)-4-morpholinyl]methyl]-1,2-dihydro-3H-1,2,4-triazol-3-one; Emend; L 754030; MK-869; ONO-7436

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