Description: Xanthotoxol is a coumarin and a major component in C. monnieri that has diverse biological activities. It inhibits proliferation of HeLa and HepG2 cells in vitro. Xanthotoxol increases histamine release from mast cells and decreases secretion of TNF-α, IL-4, and IL-1β from RBL-2H3 cells induced by DNP-human serum albumin (DNP-HSA). It is nematocidal against M. incognita. In vivo, xanthotoxol inhibits predatory mouse and rat killing behavior in dogs and cats when administered at doses ranging from 3 to 100 mg/kg and 5 to 20 mg/kg, respectively.4 It reduces amphetamine-induced hypermobility in mice and hamsters. Xanthotoxol (5 and 10 mg/kg) reduces brain edema, neutrophil infiltration, blood-brain barrier disruption, production of IL-1β, TNF-α, IL-8, and nitric oxide (NO), and levels of intercellular adhesion molecule-1 (ICAM-1) and E-selectin in a rat model of focal cerebral ischemia.
