Description
Technical Field
The invention belongs to the field of drug synthesis, and particularly relates to a novel Bruton's tyrosine kinase inhibitor, and a preparation method and application thereof.
Background
The present invention relates generally to novel compounds, methods for their preparation and their use as KRAS G12C Use of an inhibitor (e.g. for the treatment of cancer).
RAS represents a group of closely related 189 amino acid (molecular weight 21kDa) monomeric globular proteins that are associated with the plasma membrane and bind GDP or GTPoRAS as molecular switches. When the RAS contains a bound GDP, it is in a quiescent or off state and is in an "inactive state". In response to exposure of cells to certain growth-promoting stimuli, RAS is induced to convert its bound GDP to GTP. Upon binding to GTP, RAS is "turned on" and is able to interact with and activate other proteins (their "downstream targets"). The RAS protein itself has a very low intrinsic capacity to hydrolyze GTP back to GDP, leaving itself in an off state. Shutting down RAS requires an extrinsic protein called GTPase Activating Proteins (GAPs) that interact with RAS and greatly accelerate conversion of GTP to GDP. Any mutation in RAS that affects its ability to interact with GAPs or convert GTP back to GDP will result in an extended activation time of the protein, resulting in an extended cell signaling, allowing it to continue to grow and divide. Because these signals lead to cell growth and division, hyperactive RAS signals may ultimately lead to cancer.
Structurally, the RAS protein contains a G domain responsible for the enzymatic activity of RAS-ornithopterin nuclear-back-acid binding and hydrolysis (GTPase reaction). It also contains a C-terminal extension called CAAX box, can be post-translationally modified, and is responsible for targeting proteins to the membrane. The G domain is about 21-25kDa in size and comprises a phosphate binding ring (P-ring). The P-loop is the pocket for nucleic acids to bind in proteins, a rigid part of the domain with conserved amino acid residues ((glycine 12, threonine 26 and lysine 16)) that is critical for nucleic acid binding and hydrolysis. The G domain also contains the so-called Switch I (residues 30-40) and Switch II (residues 60-76) regions, both of which are dynamic parts of the protein, which are commonly referred to as "spring-loaded" mechanisms because they are capable of switching between resting and loaded states. The key interaction is the hydrogen bond formed by threonine 35 and glycine 60, with the Y-phosphate of GTP, which maintains the Switch1 and Switch2 regions in their active conformations, respectively. After hydrolysis of GTP and release of phosphate, the two relax into the inactive GDP conformation.
The most well-known members of the RAS subfamily are HRAS, KRAS and NRAS, primarily because of their association with various types of cancer. Mutations in any of the three major isoforms of RAS (HRAS, NRAS or KRAS) genes are most common in human tumorigenesis. It was found that about 30% of human tumors carry RAS gene mutations o notably, KRAS mutations were detected in 25-30% of tumors. In contrast, the rate of oncogenic mutations that occur in NRAS and HRAS family members is much lower (8% and 3%, respectively). The most common KRAS mutations were found at residues G12 and G13 and at residue Q61 of the P loop. G12C is a frequent mutation of the KRAS gene (glycine 12 to cysteine). This mutation has been found in about 13% of carcinogenesis, about 43% of lung carcinogenesis and about 100% of MYH-related polyposis (familial colon cancer syndrome).
KRAS as leading edge target G12C Mutant proteins have received much attention. Araxes (a subsidiary of Wellspring) developed ARS-853 and ARST620 compounds in 2013 and 2016, respectively. In recent years, it has also been KRAS G12C Inhibitors have been applied for a number of patents, for example W02016164675 and W02016168540MRS-853 compounds show good cell viability, but their pharmacokinetic properties are poor, which is not suitable for assessing the pharmacodynamics of animal models in vivo. Ars-1620 on KRAS G12C Has high efficiency and selectivity, and can realize rapid and continuous target action in vivo so as to induce tumor regression. The in vivo evidence provided by this study indicates that ARS-1620 represents a new generation of KRAS G12C Specific inhibitors have great therapeutic potential. Wellspring announces that the FDA has approved the IND use of ARS-3248. Other candidate KRAS G12C Inhibitors include MRTX-849 from Mirati and BI-2852 from Boehringer Ingelheim, among others. Thus, despite advances in this area, there remains a need in the art for improved compounds and methods for treating cancer, for example by inhibiting KRAS, HRAS or NRAS. The present invention fulfills this need and provides other related advantages.
Briefly, the present invention provides compounds, including stereoisomers, pharmaceutically acceptable salts, tautomers and prodrugs thereof, that are capable of modulating the G12C mutant KRAS, HRAS and/or NRAS proteins. In some cases, the compound acts as an electrophile capable of forming a covalent bond with a cysteine residue at position 12 of a KRAS, HRAS, or NRAS G12C mutein. Also provided are methods of using such compounds to treat various diseases or conditions, such as cancer.
