| | PROCHLORPERAZINE MALEATE Usage And Synthesis |
| Description | Prochlorperazine maleate (84-02-6) inhibits dynamin and clathrin-mediated endocytosis (CME) with an IC50=5.8 μM for CME.1?Increases tumor cell antigen presentation enhancing the efficacy of anti-tumor mAbs.2?A clinically useful antipsychotic agent3?with antimigraine4?and antiemetic activity5. | | Chemical Properties | Off-White Powder | | Uses | Antiemetic;Dopamine antagonist | | Uses | Antiemetic. | | Brand name | Compazine (GlaxoSmithKline). | | General Description | Prochlorperazinemaleate, 2-chloro-10-[3-(4-methyl-1-piperazinyl)propyl]phenothiazinemaleate (Compazine), is in the piperazine subgroupof the phenothiazines, characterized by high-milligramantipsychotic potency, a high prevalence of EPS, and lowsedative and autonomic effects. Prochlorperazine is more potenton a milligram basis than its alkylamino counterpart,chlorpromazine. Because of the high prevalence of EPS, however,it is used mainly for its antiemetic effect, not for its antipsychoticeffect. | | Biological Activity | D 2 receptor antagonist. Also interacts with 5-HT 3 and nAChR. Displays antipsychotic, antispasmodic, antiemetic and antinociceptive activity in vivo . | | Biochem/physiol Actions | Phenothiazine antipsychotic; D2 dopamine receptor antagonist; antispasmodic | | References | References/Citations
