Description

Heterocyclic compounds, their preparation methods and their applications in medicine Technical Field

[0001] This disclosure pertains to the pharmaceutical field and relates to a heterocyclic compound of general formula (I), a method for its preparation, a pharmaceutical composition containing the heterocyclic compound, and its use as a therapeutic agent, particularly as a VAV1 inhibitor or degrader, and in the preparation of medicaments for the treatment and / or prevention of VAV1-mediated or dependent diseases or conditions. Background Technology

[0002] The VAV family is a group of signal transduction proteins that act as nucleation-dependent GDP / GTP exchange factors (GEFs) and adaptor molecules for Rho subfamily GTPases. In vertebrates, this family consists of three members: Vav1, Vav2, and Vav3. Vav1 primarily encodes and expresses GEFs in human hematopoietic stem cells, including T cells, B cells, monocytes, natural killer (NK) cells, granulocytes, and dendritic cells, while family members VAV2 and VAV3 are more commonly expressed. The multi-domain structure of VAV1 is crucial for its activation and function; different domains regulate both GEF-dependent and GEF-independent VAV1 activity and subsequent downstream signal transduction. Regarding the function of VAV1, researchers first discovered Vav1… - / - Mice exhibited severe T cell developmental defects, including a significant reduction in the number of thymic and peripheral T cells; conversely, Vav2... – / – Vav3 – / – and Vav2 – / – / 3 – / – The mouse model showed normal T cell development, indicating the crucial role of Vav1 in T cell development; secondly, Vav1 also affects signal transduction in T / B cells, for example: Vav1 - / - CD4 +Th cells exhibited a deficiency in IL-4 expression. Furthermore, CRISPR screening further validated the crucial role of VAV1 in TCR-mediated activation and T cell effector function. When the TCR, BCR, and other cytokine receptors are activated, Vav1 is rapidly phosphorylated, activating Rac GTPases. Vav1 plays a role in various cellular functions, including actin remodeling, F-actin polymerization, TCR aggregation, integrin-mediated cell adhesion activation, immune synapse formation between T cells and antigen-presenting cells (APCs), and chemokine-mediated cell migration. VAV1 also regulates B cell cytoskeleton remodeling. In addition, Vav1 functions as a scaffold protein in GEF-independent pathways. T cells derived from GEF-inactivated VAV1 mice showed normal TCR-mediated calcium release and NFAT pathway activation in vitro. Conversely, transfection of human VAV1-deficient J.Vav1 T cells with a GEF-retaining N-terminal truncated mutant resulted in incomplete Ca2+ release, calmodulin binding, and NFAT pathway activation in vitro due to the inability to interact with phospholipase C-γ (PLCγ)1. These findings demonstrate the scaffold function of VAV1. Although the exact role of VAV1 in human diseases remains to be clinically validated, multiple pieces of evidence suggest its association with autoimmune and chronic inflammatory diseases. VAV1-deficient mice antagonize MOG(5-55)-induced EAE, a model widely used to evaluate drug efficacy against multiple sclerosis. Genomic screening of primary human T cells using the CRISPRa and CRISPRi methods also revealed VAV1 as an important positive regulator of T cell function. These findings highlight VAV1's potential as a target in autoimmune and chronic diseases. Because VAV1 lacks a distinct binding pocket, it has long been considered an untreatable target. Molecular glue degraders (MGDs) are oral small molecules that induce ubiquitination and degradation of target proteins by binding to the surface of E3 ligase complexes, representing a novel class of molecules targeting proteins without a clear binding pocket. Monte Rosa Therapeutics has designed a molecular glue, MRT-6160, targeting VAV1. Through MGD, it degrades VAV1 protein, modulates TCR and BCR-mediated activation, and inhibits T cell proliferation and cytokine production. MRT-6160 has shown excellent preclinical efficacy in animal models of arthritis and colitis, providing a solid foundation for future clinical trials. This disclosure describes a molecular glue that specifically degrades VAV1. Summary of the Invention

[0310] A "leaving group," or simply a group, is an atom or functional group that breaks off from a larger molecule in a chemical reaction. It's a term used in nucleophilic substitution and elimination reactions. In a nucleophilic substitution reaction, the reactant attacked by the nucleophile is called the substrate, and the atom or group of atoms that breaks off with a pair of electrons from the substrate molecule is called the leaving group. Groups that readily accept electrons and have a strong ability to accept negative charges are desirable leaving groups. The smaller the pKa of the conjugate acid of the leaving group, the easier it is for the leaving group to break off from other molecules. This is because a smaller pKa of the conjugate acid means that the corresponding leaving group does not need to combine with other atoms, and its tendency to exist as an anion (or an electrically neutral leaving group) is enhanced. Common leaving groups include, but are not limited to, halogens, -OTs, or -OH.

[0457] Biological evaluation

[0458] The following test examples further describe and explain this disclosure, but these test examples are not intended to limit the scope of this disclosure.

[0459] Test Example 1: VAV1 Degradation Experiment in T Cells

[0460] The degradation rate of VAV1 protein in compound-treated T cells (Jurkat) was detected using Meso Scale Discovery (MSD) to assess the degradation activity of the compound on intracellular VAV1.

[0461] Experimental steps:

[0462] Electrochemiluminescence (ECL) is a specific chemiluminescent reaction initiated by electrochemistry on an electrode surface, offering higher sensitivity and a wider linear range for the detection of target proteins. In this experiment, Jurkat cells (ATCC, catalog number TIB-152) resuspended in RPMI 1640 medium containing 10% FBS were seeded into 96-well plates and cultured at 37°C with 5% CO2. Then, compounds of different concentration gradients were added, and the plates were treated at 37°C with 5% CO2 for 24 hours, after which lysed cells were collected. VAV1 was labeled using a VAV1-specific antibody sandwich method (Thermo, MA5-17198, Proteintech, 16364-1-AP), and the VAV1-antibody complex was tagged with a SULFO tag using Anti-Rabbit Antibody Goat SULFO-TAG Labeled (MSD, R32AB-1). Using a MESO SECTOR S 600 instrument, the electrochemical excitation of the SULFO-TAG™ label to emit a strong light signal was detected, allowing for the determination of VAV1. The content of VAV1 recombinant protein was calculated using a standard curve. DMSO-treated wells were used as negative controls, and blank cell lysates were used as positive controls. Concentration-response curves of compound concentration versus VAV1 degradation rate were obtained using four-parameter nonlinear fitting with GraphPad PRISM software (version 9.00; GraphPad San Diego, CA), and the relative DC content was calculated. 50 The value is used to reflect the degradation activity of different compounds on VAV1.

[0464] Conclusion: The compound disclosed herein exhibits good degradation activity against VAV1.

[0465] Test Example 2: VAV1 Degradation Experiment in Human PBMC Cells

[0466] The degradation rate of VAV1 protein in human PBMC cells treated with the compound was detected using Meso Scale Discovery (MSD) to evaluate the degradation activity of the compound on VAV1 in human PBMC cells.

[0467] Experimental steps:

[0468] Electrochemiluminescence (ECL) is a specific chemiluminescent reaction initiated by electrochemistry on an electrode surface, offering higher sensitivity and a wider linear range for the detection of target proteins. In this experiment, cryopreserved human PBMC cells (Xuanfeng, #SLB-HP050B) were revived and resuspended in RPMI 1640 medium containing 10% FBS. The cells were seeded at a density of 500,000 viable cells per well in 90 μL of 96-well round-bottom plates (Corning #3788). Then, 10 μL of compounds diluted 4-fold with culture medium at different concentrations were added, and the plates were treated at 37°C with 5% CO2 for 24 hours. After lysing the cells with HTRF lysis buffer (Revvity, #64KL1FDF), the cells were stored at -80°C. VAV1 was labeled using a VAV1-specific antibody sandwich method (Thermo, MA5-17198, Proteintech, #16364-1-AP), and the VAV1-antibody complex was tagged with a SULFO tag using Anti-Rabbit Antibody Goat SULFO-TAG Labeled (MSD, #R32AB-1). In a MESO SECTOR S 600 instrument, the SULFO-TAG™ label was excited by electrochemical reaction to emit a strong light signal, and VAV1 was measured. The content of recombinant VAV1 protein was calculated using a standard curve. DMSO-treated wells were used as positive controls, and blank cell lysate was used as a negative control. A concentration-response curve of compound concentration versus VAV1 degradation rate was obtained using four-parameter nonlinear fitting with GraphPad PRISM software (version 10.00; GraphPad San Diego, CA), and the absolute DC-DC ratio was calculated. 50 The value is used to reflect the degradation activity of different compounds on VAV1.
