Evodiamine is a quinozole alkaloid isolated from Evodia rutaecarpa, described as an agonist of the VR1 (vanilloid receptor subtype 1, TRPV1) with affinity (Ki = 5.95 microM) comparable to that of the prototypical VR1 chemical activator Capsaicin .Evodiamine induction of 45Ca2+ uptake was competitively antagonized by the Capsaicin antagonist Capsazepine .Evodiamine is described to inhibit prostaglandin E2 synthesis, cyclooxygenase-2 induction and NF-κB activation, producing antiinflammatory effects.An antiangiogenic and antiinflammatory agonist of TRPV1.
