Abstract
The invention relates to heterocyclic derivatives, a preparation method and medical application thereof.

Description
the invention relates to a heterocyclic derivative, a preparation method thereof, a pharmaceutical composition containing the derivative and application of the heterocyclic derivative as a therapeutic agent, in particular to an inhibitor of K-Ras GTPase.
RAS represents a closely related group of monomeric globular proteins (21 kDa molecular weight) with 189 amino acids and which are associated with the plasma membrane and bind GDP or GTP. Under normal developmental or physiological conditions, the RAS is activated by receiving growth factors and various other extracellular signals, and is responsible for regulating functions such as cell growth, survival, migration, and differentiation. RAS functions as a molecular switch, the on/off state of the RAS protein is determined by nucleotide binding, the active signaling conformation binds GTP, and the inactive conformation binds GDP. When the RAS contains bound GDP, it is in a dormant or quiescent or off state and is "inactive". When cells are exposed to certain growth promoting stimuli in response, the RAS is induced to convert the bound GDP to GTP. As GTP is bound, the RAS is "on" and is able to interact with and activate other proteins (its "downstream targets"). RAS proteins themselves have a very low inherent ability to hydrolyze GTP back to GDP and thereby turn themselves into an off state. Conversion of the RAS to shut down requires exogenous proteins called Gtpase Activating Proteins (GAPs) that interact with the RAS and greatly promote the conversion of GTP to GDP. Any mutation in the RAS that affects its ability to interact with GAP or convert GTP back to GDP will result in prolonged activation of the protein and thus produce a prolonged signal to the cell that signals it to continue growth and division. These signals may therefore cause cell growth and division, and overactivated RAS signaling may ultimately lead to cancer.
Structurally, RAS proteins contain a G domain responsible for enzymatic activity of the RAS, guanine nucleotide binding and hydrolysis (gtpase reaction), which also includes a C-terminal extension containing a so-called "CAAX box", which can be post-translationally modified and targets the protein to a membrane. The G domain is approximately 21-25kDa in size and contains a phosphate binding loop (P-loop). The P-loop represents the pocket in the protein that binds the nucleotide, and this is a rigid part of the domain with conserved amino acid residues that are necessary for nucleotide binding and hydrolysis (glycine-12, threonine-26 and lysine-16). The G domain also contains so-called switch I regions (residues 30-40) and switch II regions (residues 60-76), both dynamic parts of the protein, often denoted as "spring-loaded" mechanisms due to the ability of the dynamic parts to switch between resting and loaded states. The main interaction is the hydrogen bond formed by threonine-35 and glycine-60 with the gamma-phosphate of GTP, which maintains their active conformation in switch I and switch II, respectively. After hydrolysis of GTP and release of phosphate, both relax to an inactive GDP conformation.
Among RAS family members, oncogenic mutations are most common in KRAS (85%), while NRAS (12%) and HRAS (3%) are less common. KRAS mutations are prevalent in three major deadly cancer types in the united states: pancreatic cancer (95%), colorectal cancer (45%) and lung cancer (25%), KRAS mutations are also found in other cancer types including multiple myeloma, uterine cancer, cholangiocarcinoma, gastric cancer, bladder cancer, diffuse large B-cell lymphoma, rhabdomyosarcoma, cutaneous squamous cell carcinoma, cervical cancer, testicular germ cell carcinoma, etc., whereas KRAS mutations are rarely found (< 2%) in breast, ovarian and brain cancers. In non-small cell lung cancer (NSCLC), KRAS G12C is the most common mutation, accounting for nearly half of all KRAS mutations, followed by G12V and G12D. In non-small cell lung cancer, the increase in the frequency of specific allelic mutations comes mostly from classical smoking-induced classical mutations (G: C to T: A substitutions), resulting in KRAS G12C (GGT to TGT) and G12V (GGT to GTT) mutations.
Large genomics studies indicate that lung cancer KRAS mutations, including G12C, are mutually exclusive from other known driving oncogenic mutations in NSCLC, including EGFR, ALK, ROS, RET, and BRAF, indicating the uniqueness of KRAS mutations in lung cancer. While at the same time KRAS mutations often coincide with certain co-mutations, such as STK11, KEAP1 and TP53, which in cooperation with the mutated RAS transform the cells into highly malignant and invasive tumor cells.
Three RAS oncogenes constitute the most frequently mutated gene family in human cancers. It is disappointing that despite thirty years of research efforts, there is still no clinically effective anti-RAS therapy, and targeting the gene using small molecules is a challenge. Accordingly, there is an urgent need in the art for small molecules for targeting the RAS (e.g., K-RAS, H-RAS, and/or N-RAS) and using the same to treat a variety of diseases, such as cancer.
At present, the clinical development of KRAS G12D inhibitor is in vigorous competition at home and abroad, wherein KRAS G12D inhibitor MRTX-1133 developed by Mirati Therapeutics Inc company already enters a preclinical stage and is used for treating diseases such as large intestine tumor, non-small cell lung cancer, pancreatic cancer and the like. There are a few published KRAS G12D inhibitor patent applications including WO2021041671 by Mirati Therapeutics Inc. Although research and use of KRas G12D inhibitors has advanced somewhat, there is still a tremendous space for improvement and there is still a need to continue to research and develop new KRas G12D inhibitors.
