Problems solved by technology

Many anticancer drugs contain spirocycles. The structure-activity relationship studies show that the activity of lactone ring-opening compounds is significantly higher than that of lactone compounds. Among them, the p53-MDM2 binding inhibition of indoline 6-position or benzene ring chlorinated derivatives Activity was not superior to that of the non-chlorinated derivatives

Abstract

The invention relates to a 3'-phenylspiro[indoline-3,2'-pyrrolidinyl]-2-one derivative and a preparation method and application thereof, belonging to the technical field of heterocyclic compounds. Using acetyl coumarin compounds, indole quinone compounds and amino acids as the main raw materials, the three components undergo a ring closure reaction to form a spiro ring structure, which is then reacted with the corresponding nitrogen-containing fragment to form a spiro ring Derivatives, that is, 3'-phenylspiro[indoline-3,2'-pyrrolidinyl]-2-one derivatives. The invention is applied to the preparation of anti-cancer drugs such as anti-non-small cell lung cancer and colon cancer drugs, and has the advantages of high yield, anti-tumor cell proliferation activity and the like.

Description

technical field [0001] The invention relates to a 3'-phenylspiro[indoline-3,2'-pyrrolidinyl]-2-one derivative, a preparation method and application thereof, and belongs to the technical field of heterocyclic compounds. Background technique [0002] Spiral compounds are a class of widely used intermediates in organic synthesis, and the spiro structure exists in many important natural product molecules and pharmaceuticals with physiological activity. Many anticancer drugs contain spirocycles. The structure-activity relationship studies show that the activity of lactone ring-opening compounds is significantly higher than that of lactone compounds. Among them, the p53-MDM2 binding inhibition of indoline 6-position or benzene ring chlorinated derivatives The activity was not superior to that of the non-chlorinated derivatives. From the perspective of tumor growth inhibitory activity, the introduction of chlorine atoms helps to improve the activity, and the activity of N-piperidi...
