4-Chlorobenzo[b]thiophene (CAS: 66490-33-3) is an Intermediate of Brexpiprazole (CAS: 913611-97-9). Brexpiprazole is a novel antipsychotic drug which serves as a serotonin ® dopamine activity modulator and has demonstrated efficacy as an adjunctive treatment in patients with major depressive disorder (MDD). The drug exhibits a unique pharmacological profile, acting as a partial agonist of serotonin 5-HT1A and dopamine D2 receptors and as a full antagonist of 5-HT2A and noradrenaline α1B/2C receptors, with similar subnanomolar binding affinity. The drug, which was developed by Otsuka and Lundbeck, was approved in 2015 by the FDA for the treatment of schizophrenia and as an adjunctive treatment for depression. Brexpiprazole is widely considered to be a successor to Otsuka’s antipsychotic drug aripiprazole (trade name Abilify) whose patent expired in August 2014.
