Abstract

The invention relates to pyridopyrimidine ketones derivatives and application of the pyridopyrimidine ketones derivatives in preparing antitumor drugs, belongs to the chemical pharmaceutical area, particularly relates to application of a compound with a structure shows as formula (I), wherein Ar represents a substituted benzene ring or a heterocyclic ring Het; R1 represents H or CH3; and R2 represents a substituted benzene ring, a heterocyclic ring or alkane. Experiments show that compound with a structure shown as formula (I) has varying degrees of inhibitory activity in vitro to A549 (human lung adenocarcinoma cell), HepG2 (human hepatocellullar carcinoma cell), SKOV-3 (human ovarian neoplasm), Hela (human cervical carcinoma cell) and SW620 (human colonic cancer cell), and in particular has good inhibitory activity to SW620, so that a new choice is provided for preparation of the antitumor drugs.

Description

Technical field [0001] The present invention is a chemical medicine field, which specializes in a type of pyridine and pyrine derivatives and the use of anti -tumor drugs. Background technique [0002] Cancer, also known as Malignant Neoplasm, is caused by the disorders of the cell growth and proliferation mechanism. [0003] Entering the 21st century, malignant tumors are still an important disease that affects human life and health. Its mortality rate is rising year by year. The mortality rate of malignant tumors in my country is a high level in the world.Therefore, malignant tumors have become an important disease that seriously threaten human health and social development in my country. [0004] Malignant tumor treatment is mainly divided into surgical treatment and chemotherapy.Surgical treatment is the most important effective treatment for many early and medium -term physical tumors. About 60%of physical tumors use surgery as the main treatment method.However, for the exis...
