Abstract
Twelve naturally occurring 3,4-seco-cycloartane triterpenes (1-12) isolated from Gardenia sootepensis and Gardenia obtusifolia, and eight semi-synthetic derivatives (13-20) were evaluated for their antiangiogenic activity on a rat aortic sprouting assay, an ex vivo model of angiogenesis. Among these compounds, sootepin B (1) displayed the most potent activity in terms of the inhibition of microvessel sprouting from rat aortic rings in a dose-dependent manner with IC(50) value of 4.46 μM. Its angiogenic effect was found to occur via suppression of endothelial cell proliferation and tubular formation, and was likely mediated by regulation (inhibition) of the Erk1/2 signaling pathway.
