Problems solved by technology

However, these compounds are all multi-targeted kinase inhibitors without exception, lacking selectivity for ZAK
At present, research on ZAK kinase inhibitors is still very limited, and selective small molecule inhibitors against ZAK have not been reported yet.

Abstract

The invention relates to a heterocyclic benzene sulfonamide compound with a structure as shown in a formula (I) which is described in the specification and an application of the heterocyclic benzene sulfonamide compound in preparation of a ZAK inhibitor. The heterocyclic benzene sulfonamide compound can be used for effectively and highly selectively inhibiting ZAK protein kinase and further regulating the activation of downstream JNK / SAPK, p38, ERK and other pathways. The compound can be used for preparing medicines for preventing and treating various diseases related to ZAK kinase, such as myocardial hypertrophy, myocardial fibrosis, angina pectoris, coronary heart disease, heart failure, myocardial infarction and inflammation, and has the characteristics of better pharmacokinetics, low toxicity and higher druggability.

Description

technical field [0001] The invention relates to the field of chemistry and medicine, in particular to a heterocyclic benzenesulfonamide compound and its application. Background technique [0002] ZAK kinase (Leucine-zipper and sterile-αmotif kinase) belongs to the mixed lineage kinase (Mixed lineage kinase, MLK) family, is a new type of mitogen-activated protein kinase kinase kinase (Mitogen-activited protein kinase kinase kinase, MAP3K), Widely distributed in various tissues and organs of the human body, such as heart, skeletal muscle, placenta, pancreas, lung, liver, etc. ZAK kinase consists of 800 amino acids, and its structure includes kinase domain (KD), leucine zipper (Leucine-zipper, LZ) and sterile α motif (sterile-α motif, SAM). Overexpression of ZAK kinases in vivo is closely related to cardiac hypertrophy, myocardial fibrosis, inflammation and tumor formation. Biological studies have shown that ZAK is overexpressed in infarcted cardiomyocytes. High expression o...
