Background:
Brexpiprazole-d8is intended for use as an internal standard for the quantification of brexpiprazole by GC- or LC-MS. Brexpiprazole is a serotonin (5-HT) and dopamine receptor modulator that has high affinity (Ki=<1 nm) for 5-ht1Aand 5-HT2Aserotonin, dopamine D2L, and α1B-, and α2C-adrenergic receptors in CHO cell membranes expressing the human receptors.1It acts as a partial agonist of 5-HT1A, D2L, and D3receptors (EC50s = 0.49, 4.0, and 2.8 nM, respectively) and an antagonist of 5-HT2A, 5-HT2B, as well as α1B- and α2C-adrenergic receptors (IC50s = 6.5, 14, 0.66, and 63 nM, respectively)in vitro.In vivo, brexpiprazole dose-dependently reduces conditioned avoidance response (CAR) time, inhibits locomoter hyperactivity induced by apomorphine and amphetamine, and reverses cognitive defects induced by subchronic PCP administration in rats.2It also reduces apomorphine-induced eye blinking in cynomolgus monkeys. Formulations containing brexpiprazole have been used in the treatment of schizophrenia and major depressive disorder.
