NCIt definition : An orally-active quinazolinone alkaloid with potential antineoplastic activity. Halofuginone
interferes with the signaling pathway of transforming growth factor beta (TGF beta)
and inhibits expression of matrix metalloproteinase 2, thereby inhibiting collagen
type I synthesis and inducing extracellular matrix degradation, resulting in inhibition
of angiogenesis, tumor growth, or metastasis.;
