Problems solved by technology

[0009] In short, the current EGFR-TKI still cannot solve the clinical pressure caused by drug resistance, and most of the existing drugs are EGFR reversible or irreversible inhibitors based on quinazoline or quinolineamine Toxic side effects caused by poor selectivity of wild-type cells are also inevitable
Therefore, there is an urgent need for new types, especially compounds with novel backbones, to solve the problems of drug resistance, poor selectivity, and poor pharmacokinetic properties.

Abstract

The invention discloses a pyrimidoheterocyclic compound represented as the formula (I), or a pharmaceutically acceptable salt or a stereisomer thereof, or a prodrug molecule thereof. The pyrimidoheterocyclic compound can effectively inhibit growth of various tumor cells and has an inhibiting effect on EGFR protease. The pyrimidoheterocyclic compound can be used for preparing an anti-tumor drug, and can overcome drug resistance caused by medicines in the prior art, such as gefitinib, erlotinib and the like, has a selectivity on wild non-small cell lung cancer and is excellent in pharmacokinetic property.

Description

technical field [0001] The invention belongs to the field of chemistry and medicine, and in particular relates to pyrimido heterocyclic compounds and their medicinal compositions and applications. Background technique [0002] Whether in the world or in China, chronic diseases (or non-communicable diseases) represented by malignant tumors (cancer), cardiovascular diseases, and diabetes are becoming more major long-term threats. On May 19, 2008, the World Health Organization clearly pointed out in its latest report that non-communicable diseases are becoming the deadliest "killer" of human beings. Among them, cancer ranks first. In 2004, 7.4 million people died of cancer worldwide, and the situation in China was even more serious. According to the third national retrospective survey on causes of death released at the end of April 2008, the cancer death rate among urban and rural residents in China has increased by more than 80% in the past 30 years; among them, one out of e...
