Centaureidin

Centaureidin is an orally active IFN-promoter that can be isolated from Bidens pilosa with an EC50 of 0.9 μg/mL. Centaureidin activates the Rho signal pathway, leading to actin and tubulin disassembly, and resulting in dendrite retraction and stress fiber formation in melanocytes. Centaureidin shows high tumor cell growth inhibitory activities. Centaureidin significantly inhibits paw edema in mice[1][2][3][4][5].
