Problems solved by technology

After endoscopic or surgical treatment of early gastric cancer, the 5-year survival rate can reach more than 90%. However, because the early symptoms of gastric cancer are often not obvious, most patients have already reached the advanced stage when they go to the doctor, so the overall 5-year survival rate of gastric cancer remains low. hovering at a lower level

Abstract

The invention provides a 1-styryl isoquinoline derivative and a preparation method thereof, and the 1-styryl isoquinoline derivative is synthesized by using 1-methylisoquinoline and a benzaldehyde compound as raw materials through an intermolecular nucleophilic addition elimination reaction under the catalysis of p-toluenesulfonamide. The 1-styryl isoquinoline derivative prepared by the invention has good anti-gastric cancer activity, blocks a cell cycle in a G2 / M period, and induces cell apoptosis by inhibiting a PI3K / Akt / mTOR pathway. The compound has good cytotoxicity to tumor cells, is simple to synthesize and can be applied to preparation of gastric cancer treatment drugs.

Description

technical field [0001] The invention belongs to the technical field of medicine, and specifically relates to a preparation method of 1-styryl isoquinoline derivatives; the invention also relates to the application of 1-styryl isoquinoline derivatives in the preparation of anti-gastric cancer drugs. Background technique [0002] Gastric cancer is a common malignant tumor in the world, ranking third among the related deaths caused by malignant tumors in the world. More than 70% of the new cases of gastric cancer are in developing countries, and about 50% of the cases are in eastern Asia, mainly concentrated in China. Its death rate ranks second among malignant tumors in China. After endoscopic or surgical treatment of early gastric cancer, the 5-year survival rate can reach more than 90%. However, because the early symptoms of gastric cancer are often not obvious, most patients have already reached the advanced stage when they go to the doctor, so the overall 5-year survival r...
