Abstract

The invention relates to an imidazopyridine mercapto-acetamide derivative shown as a general formula I or a medicinal salt thereof, a pharmaceutical composition containing the compound, and application of the pharmaceutical composition to the preparation of a human solid tumor resistant medicament. Human solid tumors include human large cell lung cancer, human liver cancer, human colon tumor and human breast cancer. The general formula I is shown in the description.

Description

technical field [0001] The invention relates to the application of imidazo[4,5-b]pyridine thioethanamide derivatives or pharmaceutically acceptable salts, esters or prodrugs in the preparation of anti-human solid tumor drugs, belonging to the technical field of medicine. Background technique [0002] Malignant tumors are common and frequently-occurring diseases that seriously threaten human health and survival. According to the report of the World Health Organization, tens of millions of patients die from cancer every year in the world, and in recent years, due to the aggravation of environmental pollution and bad living habits, the incidence of tumors, especially malignant tumors, and the number of cancer deaths each year are increasing year by year. rise. Drug therapy plays an important role in the treatment of malignant tumors. Although there are dozens of antitumor drugs commonly used in clinical practice, there are still many problems, such as poor water solubility, s...
