Perphenazine is a D2DR inhibitor which inhibits the glutamate dehydrogenase in vitro. Perphenazine also acts as a α-adrenergic receptor antagonist and σ-receptor agonist. Studies indicate that uncharged Perphenazine is better at forming complexes with cyclodextrins. In addition, Perphenazine forms more stable complexes with cyclodextrins than fluphenazine (sc-205700). Studies show that Perphenazine enhances the expression of CD71 on K562 cells, while at the same time inhibiting the proliferation of these cells.
