Description

Pyridolactam derivatives, preparation method and application thereof
The present application claims priority to chinese patent application 202111031560.X, entitled "pyridolactam derivatives, their preparation and pharmaceutical compositions containing the derivatives" filed on 3 months 2021, 9, and chinese patent application 202210140847.4, entitled "pyridolactam derivatives, their preparation and pharmaceutical compositions containing the derivatives" filed on 16 months 2022, 2, the contents of which are incorporated herein by reference in their entirety.
Technical Field
The present invention relates to pyridolactam derivatives, to a process for their preparation, to pharmaceutical compositions containing them and to their use as therapeutic agents, in particular as HPK1 inhibitors.
Background
Hematopoietic progenitor kinase (HPK 1, also known as MAP4K 1) is a mammalian Ste 20-like serine/threonine kinase, which is the expression product of the gene MAP4K1, mainly in hematopoietic stem cells, belongs to mitogen activated protein kinase kinase family (MAP 4K), it has now been found that this family also includes 5 other members MAP4K2, MAP4K3, MAP4K4, MAP4K5, MAP4K6.HPK1 is a protein of 97kDa in relative molecular weight, and is largely divided into 3 regions, the N-terminal Ste 20-like kinase region, the C-terminal kinase region and the middle 4 proline-rich regions (P1, P2, P3 and P4), which normally interact with the adaptor proteins containing SH2/SH3 regions, activating the transduction of a range of signal pathways.
When HPK1 is activated by a variety of upstream signaling factors, including epidermal growth factor, prostaglandin E2, tumor growth factor, erythropoietin, T cell receptors, B cell receptors, etc., a series of biological cascades are triggered. HPK1 can also interact with the adaptor protein SLP-76 family, CARD11, GRB2 family, CRK family and the like in the downstream signaling pathway to activate the JNK/SAPK signaling pathway of hematopoietic stem cells, thereby back-regulating the T cell pathway. Therefore, HPK1 is involved in regulating cell proliferation and apoptosis, and plays an important role in immunosuppression.
HPK1 acts as a kinase regulating immunosuppression and is a reverse regulator of T cell receptor, when T cell receptor is activated, HPK1 in cytoplasm recruits to the vicinity of cell membrane, activated HPK1 phosphorylates linker protein SLP76, activated SLP76 acts as docking site for T cell regulatory inhibitor protein 14-3-3, multiple proteins combine to form SLP76 complex, SLP76 complex induces ubiquitination degradation, finally leading to instability of T cell receptor signaling complex, thereby down regulating T cell signaling pathway and T cell proliferation.
T cells participate in an important process of anti-tumor immunity, and the antigen receptor of the T cells is used for recognizing specific antibodies on tumor cells to directly kill the tumor cells; or indirectly kill tumor cells by activating macrophages and secreting other lymphokines. Therefore, inhibition of HPK1 can proliferate T cells and activate T cell signaling pathways, further enhancing tumor killing and inhibiting tumor growth. Because of the important role of HPK1 in immunomodulation, HPK1 can be used as a research tool for the treatment of inflammatory responses, autoimmune diseases (e.g., systemic lupus erythematosus, psoriasis) and malignancies (e.g., acute myelogenous leukemia, bladder epithelial cancer, colon cancer, rectal cancer, pancreatic cancer, lung cancer, small cell lung cancer, non-small cell lung cancer, lymphoma, blastoma, retinoblastoma, sarcoma, prostate cancer, cholangiocarcinoma, esophageal cancer, gastric cancer, liver cancer, glioblastoma, cervical cancer, ovarian cancer, head and neck cancer, and multiple myeloma).
Only two compounds currently enter the clinic for inhibitors of the HPK1 target, namely CFI-402411 (stage two) of TREADWELL and BGB-15025 (stage one) of Baiji Shenzhou. Even so, there remains a need for safer and more effective HPK1 inhibitors that reduce the risk during treatment and reduce patient pain.

The term "leaving group (leaving group)", or leaving group, is used in the terms nucleophilic substitution reaction and elimination reaction as an atom or functional group that breaks away from a larger molecule in a chemical reaction. In nucleophilic substitution reactions, the reactant that is attacked by a nucleophile is referred to as a substrate (substrate), and the atom or group of atoms that breaks away from a pair of electrons in the substrate molecule is referred to as a leaving group. Groups that accept electrons easily and bear a strong negative charge are good leaving groups. The smaller the pKa of the leaving group conjugate acid, the easier the leaving group will be to disengage from the other molecule. The reason is that when the pKa of its conjugate acid is smaller, the corresponding leaving group does not need to be bound to other atoms, and the tendency to exist in anionic (or charge neutral leaving group) form is enhanced.

3. Electrophysiological recording procedure
3.1 Electrophysiological recording System
A fully automated QPatch system (Sophion, denmark) was used to record whole cell currents. The cells were clamped at a voltage of-80 mV. The cell clamp voltage depolarized to +20mV to activate the hERG potassium channel, and after 2.5 seconds was clamped to-50 mV to eliminate inactivation and generate an outward tail current. The tail current peak is used as a value for hERG current magnitude.
3.2QPatch Experimental procedure
After the initial stage of achieving the whole cell arrangement state of rupture of membranes, the cells were recorded for at least 120 seconds to reach stability. The voltage pattern described above was then applied to the cells every 15 seconds throughout the process. Only stable cells are allowed into the course of drug treatment in the above parameter threshold record. An external solution containing 0.1% dimethyl sulfoxide (solvent) was applied to the cells, a baseline was established, and the current was allowed to stabilize for 3 minutes. After the addition of the compound solution, the cells remain in the test environment until the effect of the compound reaches a steady state or is limited to 4 minutes. In test experiments with different gradients of compound concentration, the compound was added to the clamped cells from low to high concentration. After completion of the compound test, the cells were washed with an external solution until the current was restored to a stable state.
