    Clebopride malate
    		Antagonist 99.41%
    Clebopride malate is an orally active dopamine Receptor antagonist. Clebopride malate acts on dopamine D2 receptors and has antiemetic and prokinetic effects. Clebopride malate can be used in the study of functional gastrointestinal disorders.
  • HY-B1470

    		Antagonist 99.68%
    Azaperone (R-1929) acts as a dopamine antagonist but also has some antihistaminic and anticholinergic properties. Azaperone is a pyridinylpiperazine and butyrophenone neuroleptic agent with antiemetic effects, which is used mainly as a tranquilizer in veterinary medicine.
  • HY-B0965A
    Thioridazine
    		Antagonist 99.50%
    Thioridazine, an antagonist of the dopamine receptor D2 family proteins, exhibits potent anti-psychotic and anti-anxiety activities. Thioridazine is also a potent inhibitor of PI3K-Akt-mTOR signaling pathways with anti-angiogenic effect. Thioridazine shows antiproliferative and apoptosis induction effects in various types of cancer cells, with specificity on targeting cancer stem cells (CSCs).
