Abstract

The invention provides a novel anti-tumor drug which is represented by the molecular formula (I) and specifically relates to anti-tumor 2-amino nicotinonitrile. The invention further provides a synthetic method of the anti-tumor drug. The method includes dissolving 2mmol of vanillic aldehyde or 2mmol of syringaldehyde, 2mmol of acetophenone and 2mmol of malononitrile in 1, 4-dioxane, then adding 4mmol of ammonium acetate, heating a mixture at the temperature of 120 DEG C for reaction for 20 minutes by using a microwave with the length of 300W as an assistant, adding ice water to the reaction mixture to separate out a product, and finally subjecting the mixture to recrystallization to obtain the 2-amino nicotinonitrile. The synthetic method of the anti-tumor drug is simple, and the anti-tumor drug can be rapidly and efficiently synthesized by means of a one-pot four-component reaction assisted by the microwave. The anti-tumor drug which is represented by the molecular formula (I) is capable of obviously inhibiting activities of proliferation of liver cancer cells, gastric cancer cells, breast cancer cells, pancreatic cancer cells, brain cancer cells, lung cancer cells and ovarian cancer cells.

Description

1. Technical field

[0001] The invention provides a novel 2-aminonicotinonitrile antitumor drug, a pharmaceutical composition containing the compound and its use as an antitumor agent, belonging to the technical field of medicine. 2. Background technology

[0002] Malignant tumors seriously threaten human life and health. About 7 million people die from cancer every year in the world, accounting for about a quarter of the total death toll. Gastric cancer is the most common malignant tumor in my country, and its death rate accounts for the first place among all kinds of malignant tumors. Liver cancer is the second cancer "killer" in my country, and it has jumped to the first place in some high-incidence areas of liver cancer, accounting for 45% of liver cancer deaths worldwide. At present, the mortality rate of existing cancer patients exceeds 30%, which has become the second largest factor in the death of Chinese residents. Pancreatic cancer is one of the cancers with the h...
