Rolapitant cas 552292-08-7

Rolapitant is an azaspiro compound that is 1,7-diazaspiro[4.5]decan-2-one carrying additional phenyl and 1-{[3,5-bis(trifluoromethyl)phenyl]ethoxy}methyl substituents at position 8. Used (in the form of the hydrochloride hydrate) for the prevention of delayed nausea and vomiting associated with initial and repeat courses of emetogenic cancer chemotherapy. It has a role as an antiemetic and a neurokinin-1 receptor antagonist. It is an ether, an azaspiro compound, a member of pyrrolidin-2-ones, a member of piperidines and an organofluorine compound. It is a conjugate base of a rolapitant(1+).|Rolapitant is a potent, highly selective, long-acting Neurokinin-1 (NK-1) receptor antagonist approved for the prevention of delayed chemotherapy-induced nausea and vomiting (CINV) in adults. Delayed-phase CINV typically occurs >24 hours after chemotherapy treatment and is principally mediated by Neurokinin-1 and its ligand Substance P, which is released in the gut following chemotherapy administration. Neurokinin-1 is also known as Tachykinin Receptor 1 (TACR1), Neurokinin 1 Receptor (NK1R), and Substance P Receptor (SPR). By blocking Substance P from interacting with NK-1 receptors in the gut and the central nervous system, rolapitant prevents late-phase CINV. Unlike other available NK-1 receptor antagonists, rolapitant is not an inhibitor of Cytochrome P450 enzyme CYP3A4 and has a long elimination half-life, allowing a single dose to prevent both acute and late-phase CINV during the first 120 hours post-chemotherapy.|Rolapitant is a Substance P/Neurokinin-1 Receptor Antagonist. The mechanism of action of rolapitant is as a Neurokinin 1 Antagonist, and Cytochrome P450 2D6 Inhibitor, and Breast Cancer Resistance Protein Inhibitor, and P-Glycoprotein Inhibitor.|Rolapitant is an orally available antiemetic agent that is used to prevent cancer chemotherapy related nausea and vomiting. Rolapitant therapy has not been associated with serum enzyme elevations or with instances of clinically apparent liver injury with jaundice.
Rolapitant [5S,8S)-8-[[(1R)-1-[3,5 bis(trifluoromethyl phenyl] ethoxy]methyl]-8-phenyl-1,7-diazaspiro[4.5]decan-2-one] is a highaffinity NK1 receptor antagonist recently approved under the name Varubi as a treatment for nausea and vomiting caused by chemotherapy by the U.S. Food and Drug Administration (FDA). Rolapitant is metabolized in vivo primarily by CYP3A4 to form the major metabolite M19.[3]
