Description

Technical Field

[0001] The present invention belongs to the field of pharmaceutical chemistry, and specifically relates to a class of tricyclic compounds as MALT1 inhibitors, and pharmaceutical compositions and applications thereof. Background Art

[0002] MALT1 (Mucosa-associated lymphoid tissue lymphoma translocation protein 1) was discovered in mucosa-associated lymphoid tissue lymphoma and is a key regulator of the NF-κB signaling pathway. NF-κB is a transcription factor that plays a key regulatory role in lymphocyte activation, survival, and proliferation. This pathway is activated through different receptors, including T cell antigen receptor (TCR), B cell antigen receptor (BCR), tumor necrosis factor receptor (TNFR), and B cell activating factor receptor (BAFF). Depending on the receptor, the NF-κB signaling pathway can be divided into classical pathways and non-classical pathways.

[0003] MALT1 is the only caspase in the human body, which transmits signals from B cell receptors and T cell receptors. MALT1 exerts its enzymatic activity through the CBM protein complex, which is composed of multiple subunits of three proteins: CARD11 (Caspase recruitment domain family member 11, also known as CARMA1), BCL10 (B-Cell CLL / lymphoma 10) and MALT1. The CBM complex is considered to be a driver of ABC-type diffuse large B-cell lymphoma (ABC-DLBCL). MALT1 has both scaffold protein function and protease function, and regulates the NF-κB signaling pathway through two mechanisms of action. The first mechanism is the scaffold protein function, which activates the signaling pathway by recruiting NF-κB signaling pathway related proteins such as TRAF6 and TAB-TAK1. In addition, as a cysteine ​​enzyme, it inactivates the negative regulators of the NF-κB signaling pathway by cutting negative regulators of the NF-κB signaling pathway such as RelB, A20, etc., thereby activating the NF-κB signaling pathway. Activation of the NF-κB signaling pathway leads to excessive proliferation of T and B lymphocytes and secretion of cytokines such as IL-2, which in turn leads to related cancers or autoimmune diseases. Therefore, targeting the MALT1 protein to inhibit excessive activation of the NF-κB signaling pathway can provide a new treatment for cancer or autoimmune diseases. In addition, ibrutinib resistance in chronic lymphocytic leukemia (CLL) is an urgent problem to be solved. The mechanism of resistance is the presence of gene mutations in BTK or BTK downstream gene PLCG2. Studies have found that inhibiting MALT1 activity can work in ibrutinib-resistant CLL cells.

[0004] In another MCL study at the MD Anderson Cancer Center in the United States, it was found that 28.8% of 110 MCL patients had gene mutations in the NF-κB pathway, and NF-κB signaling was activated in ibrutinib-resistant MCL cells. In MCL cell lines, ibrutinib-resistant cells had higher MALT1 expression, indicating that targeting MALT1 may solve the problem of drug resistance.

[0005] In general, the development of MALT1 inhibitors has great clinical application prospects for cancer, especially various blood tumors, immune disease treatment, and overcoming drug resistance. Summary of the invention

[0006] The purpose of the present invention is to overcome the problems existing in the prior art and provide a class of tricyclic compounds as MALT1 inhibitors and their pharmaceutical compositions and uses, which exhibit good inhibitory activity on tumor cells and good drugability and have broad prospects for drug development.
