casticin/achillea

We studied the mechanism of anti-tumor activity of the flavonoid Casticin, derived from Achillea millefolium. Casticin anti-tumor activity results in cell growth arrest in G2/M and in apoptotic death. As a tubulin-binding agent (TBA), Casticin induces p21, which in turn inhibits Cdk1. Moreover,

Column chromatography on silica gel of a petroleum ether extract of the flowering heads of Achillea millefolium L. allowed three flavones to be separated and identified. Spectral studies (PMR, mass spectrometry, and UV) and a comparison with data for compounds reported in the literature established

The antiproliferative activities of n-hexane, chloroform, aqueous-methanol and aqueous extracts of the aerial parts of the Achillea millefolium aggregate on three human tumour cell lines were investigated by means of MTT assays. The chloroform-soluble extract exerted high tumour cell proliferation
