a typical antipsychotic drug (APD) associated with an increased risk of extrapyramidal side effects (EPSs) and hyperprolactinemia relative to atypical APDs such as clozapine. Both drugs are dopamine D2 receptor (D2R) antagonists, with contrasting kinetic profiles. Haloperidol displays fast association/slow dissociation at the D2R, whereas clozapine exhibits relatively slow association/fast dissociation
A novel and regioselective approach to carbonyl-containing alkylchlorides via silver-catalyzed ring-opening chlorination of cycloalkanols is reported. Concurrent C(sp3)–C(sp3) bond cleavage and C(sp3)–Cl bond formation efficiently occur with good yields under mild conditions, and the chlorinated products are readily transformed into other useful synthetic intermediates and drugs. The reaction features
The synthesis of some 4-hydroxy-(or amino)-ethyl-amino butyrophenones or butyrothienones is described. The interconversion of these compounds to the corresponding 5-aryl-4-oxa-1-azabicyclo[3,3,0]octanes is presented. The title compounds demonstrated good antiinflammatory activity in the adjuvant induced disease model. They also possessed antinociceptive, immuno-modulating and antioxidant activity, properties which are probably involved in the mechanism of their action.
