Abstract

The invention discloses a chalcone analogue containing 2-methyl-4-oxo-quinazoline-6-base, shown in a general formula (I), wherein the definitions of Ar1 and Ar2 are shown in the description. Besides, the invention further discloses a preparation method and a medical composition of the chalcone analogue containing 2-methyl-4-oxo-quinazoline-6-base. The chalcone analogue containing 2-methyl-4-oxo-quinazoline-6-base, shown in the general formula (I), has an inhibiting effect on cell proliferation of human colonic carcinoma (HCT-116) and human breast cancer (MCF-7), and can be used as an antitumor drug.

Description

technical field [0001] The present invention relates to the field of medicinal chemistry, more specifically to chalcone analogues containing 2-methyl-4-oxoquinazolin-6-yl, their preparation methods and their application in antitumor drugs . Background technique [0002] 1,3-diaryl-2-propen-1-ones (1,3-diaryl-2-propen-1-ones), commonly known as chalcone (chalcone), is an important class of secondary metabolites in plants As well as natural precursors of synthetic flavones and isoflavones. Chalcone consists of two aromatic rings, A and B, and an α, β-unsaturated carbonyl system connecting the two rings. In the literature, the aromatic ring connected to the carbonyl group is usually called the A ring, and the aromatic ring connected to the carbon-carbon double bond is called the B ring. Studies have shown that natural or synthetic chalcones have a wide range of pharmacological activities, including antitumor activities [Zhu, C.; Zuo, Y.; Wang, R.; Liang, B.; Yue, X.; Wen, G...
