Abstract

The invention discloses application of an amine derivative in preparation of an anti-tumor medicine composition, and particularly relates to application of an N-(tert-butyl)-3-methyl-1, 2, 4-oxadiazole-5-amine derivative in preparation of an anti-tumor medicine composition. The N-(tert-butyl)-3-methyl-1, 2, 4-oxadiazole-5-amine derivative provided by the invention has a remarkable inhibition effect on liver cancer, lung cancer, cervical cancer, breast cancer, stomach cancer and lymph cancer, shows excellent anti-tumor characteristics, can be used as an anti-tumor lead drug molecule, and has a good development and application prospect in the aspect of developing anti-tumor drugs.

Description

【Technical field】 [0001] The invention relates to the technical field of antitumor drugs, and relates to the application of an amine derivative in the preparation of an antitumor drug composition, in particular to N-(tert-butyl)-3-methyl-1,2,4-oxadi Application of azole-5-amine derivatives in the preparation of antitumor pharmaceutical compositions. 【Background technique】 [0002] Tumor is a malignant abnormal hyperplasia caused by abnormal cell mutation or genetic variation, and the body loses its normal regulation of growth and reproduction. At present, with the increasing morbidity and mortality worldwide, the prevention and treatment of cancer has become a world public health focus of attention. The research and development of new anti-tumor drugs to save more patients suffering from cancer is the commanding heights of health that countries are competing for. [0003] At present, there have been many studies on antineoplastic drugs. For example, Chinese patent applicat...
