quinazolinone

4(3H)-Quinazolinone (4-Hydroxyquinazoline) is a chemically synthesized masonry block, a biologically active nitrogen heterocyclic compound. It possesses various biological properties such as antibacterial, antifungal, anticonvulsant, anti-inflammatory, anti-HIV, anticancer and pain relieving activities.

Halofuginone specifically inhibits collagen type I gene expression and matrix metalloproteinase 2 (MMP-2) gene expression, which may result in the suppression of angiogenesis, tumor stromal cell development, and tumor cell growth. Halofuginone Hydrobromide is the hydrobromide salt of halofuginone, a semisynthetic quinazolinone alkaloid anticoccidial derived from the plant Dichroa febrifuga, with antifibrotic and potential antineoplastic activities. These effects appear to be due to halofuginone-mediated inhibition of the collagen type I and MMP-2 promoters. Collagen type I and MMP-2 play important roles in fibroproliferative diseases.

Febrifugine is an effective coccidiostat, possesses schizonticide props; it and its derivatives shows high degree of antimalarial activity but use limited by toxicity .

Febrifugine dihydrochloride (Propyldazine hydrochloride) is a biochemical with therapeutic activity regarding malaria, cancer, fibrosis and inflammatory diseases.
