Problems solved by technology

[0004] In recent years, the US FAD has successively approved multiple ALK inhibitors, such as crizotinib, ceritinib, etc., as well as the third-generation EGFR inhibitors currently in the late clinical stage, such as AZD9219, CO1686, etc., but currently There are still problems such as poor curative effect or low selectivity of similar drugs, so it is urgent to discover and find a class of new therapeutic drugs with high mutation resistance selectivity or multi-target inhibitory activity

Abstract

The invention discloses a nitrogen-containing heterogeneous ring compound, a preparation method thereof and an application of the nitrogen-containing heterogeneous ring compound in inhibition of kinase activity. The general formula of the nitrogen-containing heterogeneous ring compound is represented as a formula I or a formula I', wherein R1, R2, R3 and R4 in the formula I or the formula I' are selected from any one of hydrogen, halogen, cyanogroup, hydroxyl, amidogen and substituted or unsubstituted C1-C6 alkyl groups independently, and a 3-10-membered ring system can be formed by any two groups in R1, R2, R3 and R4; M1, M2 and M3 are selected from CRa or N independently, and at least one of M1, M2 and M3 is N; W is selected from substituted or unsubstituted C1-C6 alkyl groups, substituted or unsubstituted C2-C6 alkenyl, unsubstituted or halogenated 4-8-membered alkine groups, substituted or unsubstituted C3-C8 naphthenic base, substituted or unsubstituted 4-8-membered heterocyclic groups, 5-10-membered aromatic or heteroaryl groups, substituted carbonyl, substituted sulfonyl and substituted or unsubstituted amidogen. The nitrogen-containing heterogeneous ring compound can inhibit EGFR (epidermal growth factor receptor) mutant kinase activity or ALK (anaplastic lymphoma kinase) activity and is a multi-target tumor therapeutic drug with a brand-new action mechanism.

Description

technical field [0001] The invention relates to a nitrogen-containing heterocyclic compound, a preparation method thereof and an application in inhibiting kinase activity, belonging to the technical field of medicinal chemistry. Background technique [0002] Molecular targeted therapy of tumors is based on the key proteins closely related to the occurrence and development of tumors, and selectively acts on signaling proteins by chemical means to kill tumor cells. The characteristics of targeted therapy are: high specificity, strong selectivity, and lower toxicity and side effects compared with traditional chemotherapy drugs; when used in combination, it can enhance the efficacy of traditional chemotherapy; targeted inhibitors are prone to drug resistance in clinical practice and make the therapeutic drugs invalidated. [0003] Lung cancer is the malignant tumor with the highest morbidity and mortality in the world, and the 5-year survival rate is only 16.8%. In 2010, the mo...
