This study evaluated the anti-angiogenic activities of erianin
in vivo and
in vitro. Erianin, a natural product from
Dendrobium chrysotoxum, caused moderate growth delay in xenografted human hepatoma Bel7402 and melanoma A375 and induced significant vascular shutdown within 4 h of administering 100 mg/kg of the drug. Erianin also displayed potent anti-angiogenic activities
in vitro: it abrogated spontaneous or basic fibroblast growth factor-induced neovascularisation in chick embryo; it inhibited proliferation of human umbilical vein endothelial cells (EC
50 34.1
±
12.7 nM), disrupted endothelial tube formation, and abolished migration across collagen and adhesion to fibronectin. Erianin also exerted selective inhibition toward endothelial cells, and quiescent endothelium showed more resistance than in proliferative and tumour conditions. In a cytoskeletal study, erianin depolymerised both F-actin and β-tubulin, more significantly in proliferating endothelial cells than in confluent cells. In conclusion, erianin caused extensive tumour necrosis, growth delay and rapid vascular shutdown in hepatoma and melanoma models; it inhibited angiogenesis
in vivo and
in vitro and induced endothelial cytoskeletal disorganisation. These findings suggest that erianin has the therapeutic potential to inhibit angiogenesis
in vivo and
in vitro.
