Description

Pyridazine compound, pharmaceutical composition and application thereof Technical Field

The invention belongs to the field of pharmaceutical chemistry, and particularly relates to a pyridazine compound, a pharmaceutical composition and application thereof.

Background

Rat sarcoma protein (RAS protein) is an important regulator of signal transduction in humans, regulating important physiological processes including cell proliferation, differentiation, migration and survival. RAS belongs to guanosine triphosphate hydrolase (GTPase), and controls a plurality of important signal paths such as downstream RAF/MEK/ERK, PI3K/AKT and the like through the active state of the combination of RAS and Guanosine Triphosphate (GTP) and the circulation of an inactive state of the combination of RAS and Guanosine Diphosphate (GDP). This cycle involves two processes in which negative regulation catalyzes the hydrolysis of RAS-GTP to RAS-GDP by GTPase Activator (GAP), positive regulated guanylate interchange factor (GEF) catalyzes the dissociation of RAS from GDP, and RAS then binds to high intracellular concentrations of GTP. SOS1 (Son of Sevenless 1) is one of the most widely expressed and functionally important GEFs in humans.

The RAS protein family includes KRAS (KIRSTEN RAT sarcoma viral oncogene), NRAS (neuroblastoma RAS viral oncogene) and HRAS (Harvey murine sarcoma viral oncogene), with KRAS mutations leading to tumors most common. KRAS mutations result in the protein being in the state of RAS-GTP at all times, continuing to activate downstream signaling pathways, and SOS1 plays an important role in this oncogenic process. Knockout of SOS1 can effectively reduce the growth rate of KRAS mutant tumor and does not affect the growth of KRAS wild type cell line.

The small molecule inhibitor is combined with a catalytic pocket of SOS1 to influence the combination of SOS1 and RAS protein, and can effectively inhibit the phosphorylation level of RAS signal channels downstream such as ERK (extracellular regulated protein kinases), thereby inhibiting the growth of tumors. Currently, the small molecule SOS1 inhibitor BI-1701963 (WO 2018115380, WO 2019122129) developed by Bolin and Yinham is in phase I clinical studies and a combination regimen was developed in cooperation with the KRAS G12C inhibitor MRTX-849 of Mirati. In addition, bayer Inc. (WO 2018172250, WO 2019201848) and Revolition Inc. (WO 2020180770, WO 2020180768) have issued a number of patents in this field, but there is still an urgent need in the art to develop effective drugs capable of inhibiting SOS1 interactions with RAS muteins.
