Abstract

The invention discloses a coupling compound or salt or a stereoisomer or prodrug molecules, which are pharmaceutically acceptable. The coupling compound of the structure shown in the formula I or II or III is formed by connecting NSAID anti-inflammatory pain killers and an EGFR kinase inhibitor through ester bonds, wherein the R is the NSAID anti-inflammatory pain killers. The coupling compound obtained by coupling the NSAID anti-inflammatory pain killers and the EGFR kinase inhibitor has the good cancer treatment effect, and the new drug is provided for clinic treatment choices.

Description

technical field [0001] The invention belongs to the field of chemical medicine, and in particular relates to a coupling compound of a class of NSAID anti-inflammatory analgesic drugs and EGFR kinase inhibitors or pharmaceutically acceptable salts or stereoisomers thereof and prodrug molecules and their synthesis methods and Application in synthetic medicine. Background technique [0002] Tumor is a common disease with high mortality in modern society. The traditional method of treating tumors is mainly based on radical surgical resection, supplemented by preoperative and postoperative chemotherapy, but the curative effect is not satisfactory. Targeted drugs have attracted much attention due to their strong specificity and low toxicity. [0003] Studies in recent years have shown that the high expression of epidermal growth factor receptor (EGFR) in most tumors is closely related to the occurrence, development and prognosis of tumors. Therefore, targeted drugs targeting EGF...
