Abstract

The invention discloses N'-aryl acetyl o-pyridine hydrazide derivatives represented by the formula I and pharmaceutically acceptable salts and preparation methods thereof, a composition containing one or more of the compounds, and an application of the compounds in treatment of protein kinase related diseases, such as immune disorder and tumor disease.

Description

field of invention [0001] The present invention relates to N′-aryl acetyl-o-pyridine hydrazide derivatives shown in formula I, pharmaceutically acceptable salts thereof, and preparation methods thereof, compositions containing one or more of these compounds, and the use of such compounds in the treatment of The protein kinase-related diseases, such as immune disorders and tumor diseases, belong to the field of medical technology. Background of the invention [0002] In recent years, due to the improved understanding of enzymes and other disease-related biomolecules, the discovery or development of new drugs for the treatment of diseases has been greatly promoted. Protein kinases are an important class that has been extensively studied. It is a A large family involved in the control of various signal transduction processes in cells. Due to the conservation of their structure and catalytic function they are thought to have evolved from a common ancestral gene. Almost all kin...
