Pheniramine
Pheniramine (Prophenpyridamine;Tripoton) is a first-generation histamine H1 receptor antagonist, acts on the central nervous system (CNS) with sedative and hypnotic effect. Pheniramine displays antitumor effect and induces leukemia cells apoptosis. Pheniramine is also a safe and effective local agent that can suppress or relieve pain, with antipruritic effects.

Biological Activity

H1 Receptor 1.01 mM (IC50) |
Pheniramine inhibits CYP2D6, the specific P450-isozymes, to delay metabolic time and prolong antihistaminic effects[1].
Pheniramine inhibits Ca2+ influx into BC3H-1 cells by inhibiting histamine with an IC50 value of 1.01 mM and regulates cellular Ca2+ transmembrane action[2].
Pheniramine (0.5, 1.0 mM; 24 h) induces cell apoptosis in human T-cell acute lymphoblastic leukemia cell lines[3].
Pheniramine (1 μM-1 mM; 12-48 h) inhibits cell proliferation in a time-dependent manner and shows inhibitory concentration IC50s of 550 μM (CCRF-CEM cells) and 420 μM (Jurkat cells), respectively[3].
