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].

Centaureidin (2 μg/mL, 24-72 h) can stimulate IFN-γ transcription in a T cell line and Jurkat cells[1].
Centaureidin (0.5 μM, 6 days) inhibits melanosome transfer and induces cell morphological change in NHEM cells[2].
Centaureidin (0.5 μM, 24-72 h) reduces dendricity and stress fiber formation of NHEM cells [2].
Centaureidin (0.5 μM, 30-240 min) activates the Rho signal pathway, but not Rac or CDC42 in NHEM cells [2].Centaureidin (72 h) shows high cell growth inhibitory activities with IC50s of 0.0819 μM (HeLa cells), 0.1250 μM (MCF-7 cells), 0.3540 μM (A-431 cells)[3].
Centaureidin (10-100 μM) completely relaxes, in a concentration-dependent fashion, the contractions induced by Norepinephrine (NA) (HY-13715) (IC50 = 16.7 μM) or by a high K concentration (IC50 = 16.1 μM ) in intact rat aortic rings[4].
