The invention relates to new application of alantolactone, in particular to application of the alantolactone serving as an anti-
angiogenesis drug. The application has the advantages that the activity of an HUVEC (
Human Umbilical Vein Endothelial Cell) is detected through a CCK-8 method, and a
cell mobility inhibition experiment, a
cell migration inhibition experiment, a
tube formation inhibition experiment, an in-vivo anti-
angiogenesis activity experiment and the like show that the alantolactone can effectively
resist angiogenesis. The application shows that the alantolactone has an inhibition effect on an MDA-MB-231
breast tumor and has a prospect of treating a
breast cancer. A first research on a VEGFR2 and downstream
signal passageway shows that the alantolactone can obviously inhibit
phosphorylation of the VEGFR2 and also obviously inhibit
phosphorylation of VEGFR2 downstream
signal molecules including PLC(gamma)1, FAK, Src and AKT.
