Cat. No. Product Name Effect Purity
  • HY-12708
    Chlorpromazine
    Antagonist 99.61%
    Chlorpromazine is an orally active, blood-brain barrier-transparent antipsychotic agent that effectively antagonises D2 dopamine receptors and 5-HT2A, which is widely used in schizophrenia and other psychiatric disorders. Chlorpromazine exerts anti-cancer activity through a variety of pathways, including anti-proliferation, induction of autophagy and cycle arrest (G2-M phase), inhibition of cytochrome c oxidase (CcO), inhibition of tumour growth and metastasis, and inhibition of tumour immune escape. Chlorpromazine also blocks hNav1.7 channels (IC50=25.9 μM; concentration-dependent) and HERG potassium channels (IC50=21.6 μM), which has potential for analgesic and cardiac arrhythmic studies. Chlorpromazine also can inhibit clathrin-mediated endocytosis.
