Biochem/physiol Actions
5-(4-Phenoxybutoxy)psoralen (PAP-1) is derived from 5-methoxypsoralen, a natural compound. PAP-1 show higher selectivity for Kv1.3 (voltage-gated potassium channels) than other Kv1 family members. Kv1.3 is predominant on cell membranes of activated effector memory T-cells. Inhibition of Kv1.3 results in membrane depolarization. In rat models, PAP-1 is known to delay the onset of diabetes. It might be used in the treatment of psoriasis and effector memory T cells mediated autoimmune diseases. Oral, intraperitoneal and topical administration of PAP-1 prevents allergic contact dermatitis induced by oxazolone.
Selective inhibitor of Kv1.3, voltage-gated K+ channel.
Selective inhibitor of Kv1.3, voltage-gated K+ channel. PAP-1 (EC50=2 nM) potently inhibits human T effector memory cell proliferation and delayed hypersensitivity. Effective orally or intraperitoneally. 5-(4-Phenoxybutoxy)psoralen has 23-fold selectivity for Kv1.3 over Kv1.5, and 33-125-fold selectivity over other Kv1 family channels.
