Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of medicine, in particular to a compound with KRAS inhibitory effect, uses and methods of preparation. BACKGROUND

[0002] Kirsten rat sarcoma 2 viral oncogene homolog (KRas) is a small GTPase and a member of the Ras family. KRas protein is in an inactive state when it binds to GDP; when extracellular growth differentiation factors and the like transmit signals to the KRAS protein, the protein binds to GTP and becomes activated, thereby activating KRAS and downstream signals (Nature Review Cancer 3: 11-22, 2003). The RAS-RAF-MEK-ERK and RAS-PI3K-AKT signaling pathways regulate multiple cellular processes, including cell proliferation, differentiation, and survival. KRAS mutations can continuously activate downstream cell signals, promote cell proliferation, migration, and anti-apoptosis, and induce tumor occurrence.

[0003] KRAS mutations are closely related to tumor formation and development. The role of KRAS in malignancies has been observed more than 30 years ago (see, e.g., Santos et al. (1984) Science 223:661-664). Aberrant expression of KRAS is found in about 20% of all human tumors, and KRAS mutations are detected in 25-30% of lung adenocarcinomas (see, e.g., Samatar and Poulikakos (2014) Nat Rev Drug Disc 13(12):928-942 doi:10.1038 / nrd428). 80% of KRAS mutations occur at codon 12, causing a single amino acid substitution, among which the most predominant are G12C and G12D. KRAS G12C mutation refers to the mutation of glycine at position 12 of the protein to cysteine, and the frequency of tumor occurrence is in turn pancreatic cancer (57%), colorectal cancer (35%), biliary tract cancer (28%), small intestine cancer (17%), lung cancer (16%), endometrial cancer (15%) and ovarian cancer (14%) and the like (Seminars in Cancer Biology. 2019 Jun 27. pii: S1044-579X(18)30060-9). KRAS G12D mutation refers to the mutation of glycine at position 12 of the protein to aspartic acid, and the frequency of tumor occurrence is in turn pancreatic cancer (25.0%), colon cancer (13.3%), rectal cancer (10.1%), non-small cell lung cancer (4.1%) and small cell lung cancer (1.7%) and the like (see, e.g., The AACR Project GENIE Consortium, (2017) Cancer Discovery; 7(8):818-831. Dataset Version 4). In addition to G12C, G12D, KRAS has other mutations, such as G12V, G12A, G12R, G12S, G13D, Y96D, etc. Different KRAS mutations also have different frequencies in different types of cancer cells.

[0004] Due to the frequent mutations of KRAS found in various tumor types, it has become a popular anticancer target in the pharmaceutical industry (see McCormick (2015) Clin Cancer Res. 21(8): 1797-1801). The development of KRAS small molecule inhibitors is generally divided into three methods: (i) competitive ligands to prevent GTP binding; (ii) allosteric modulation to lock KRAS G12C in an inactive state; (iii) disruption of KRAS interaction with its effector proteins and guanine nucleotide exchange factors (GEFs) such as son of sevenless (SOS), RAF, and PI3K, by protein-protein interaction inhibitors.

[0005] Over the past decades, the development of drugs targeting KRAS has mostly failed, so KRAS has been considered undruggable. However, in recent years, with the breakthrough progress in biology and protein structure, including comparative studies of different structures of mutant and wild-type KRAS proteins, small molecule inhibitors targeting KRAS G12C have been successful in clinical trials. Amgen's First-in-Class KRAS G12C inhibitor AMG 510 has been approved by the US FDA for marketing on May 28, 2021, for the treatment of locally advanced or metastatic non-small cell lung cancer with KRAS G12C mutation. Mirati and many biopharmaceutical companies at home and abroad are also developing drugs targeting KRAS, but most of them are targeting KRAS G12C or KRAS G12D mutations. As mentioned above, in addition to KRAS G12C or KRAS G12D mutations, KRAS has other mutations, such as G12V, G12A, G12R, G12S, G13D, Y96D, etc. These KRAS mutations play an important role in the formation and development of various types of cancer. Therefore, it is urgent to develop drugs targeting these KRAS mutations. In addition, with the successful marketing of drugs targeting KRAS G12C, we expect that cancer patients receiving treatment will develop drug resistance. Therefore, in order to meet the unmet clinical needs, it is of great significance to develop innovative new generation broad-spectrum KRAS inhibitors targeting multiple KRAS mutations to combat drug resistance mechanisms.

Furthermore, unless otherwise explicitly set forth herein, the use of any form of the terms "comprise", "comprises", "comprising", "include", "includes" or "including" is not intended to exclude any additional features, steps, components, elements, items or steps.

[0057] The compounds of the present disclosure can be asymmetric, e.g., having one or more stereocenters. Unless in particular contexts, otherwise indicated, all stereoisomers are included, e.g., enantiomers and diastereomers. Compounds of the present disclosure containing asymmetric carbon atoms can be isolated in optically active form or as racemic mixtures. Optically active forms can be obtained from racemic mixtures by separation of the enantiomers or by synthesis from chiral precursors or chiral reagents. Racemates, diastereomers, enantiomers are all included within the scope of the present disclosure.

[0058] The compounds of the present disclosure also include tautomeric forms. Tautomeric forms arise from the exchange of a single bond and the adjacent double bond together with the migration of a proton.

[0059] The term "optionally" or "optional" means that the subsequently described event or circumstance can or can not occur, and this description includes instances where the event or circumstance occurs and instances where it does not.

[0060] Numerical ranges as used herein are inclusive of the numbers given as endpoints. For example, a range of 1 to 10 includes 1 and 10. 1-6 " C3-6" means that the group can have 3 carbon atoms, 4 carbon atoms, 5 carbon atoms, or 6 carbon atoms.

[0061] The term "substituted" or "substitution" means that any one or more hydrogen atoms on a particular atom or group is / are replaced with a substituent, as long as the valence of the particular atom or group is not normally and the substituted compound is stable.

Unless otherwise specified, the kind and number of substituents can be any that are chemically possible, on a basis of chemistry.

[0062] In the present disclosure, when any variable (e.g., Rn) occurs more than one time in a compound or substituent, its definition in each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is substituted with 1-5 R groups, then each R group is selected independently of the others. Moreover, combinations of substituents and / or variables are permissible only if such combinations result in stable compounds.

[0476] A427 cells expressing the KRAS G12D mutation were cultured in MEM medium (Gibco) containing 10% fetal bovine serum (FBS). Once the cells reached the logarithmic growth phase, the A427 cells were resuspended in serum-free medium at a density of 3.125 × 10⁶ cells / year. 5Cells were seeded at 25,000 cells / well in 96-well cell culture plates in 80 μl / well of cell culture medium at a density of 25,000 cells / ml and incubated overnight in a cell culture incubator (37°C, 5% C02). The next day, 20 μl of compound diluted in serum-free medium was added to each well. After 4 hours of incubation in a cell culture incubator (37°C, 5% C02), the culture medium was removed from the 96-well plates and 50 μl / well of 1 x cell lysis buffer (Cisbio) was added. The plates were incubated for 30 min at room temperature with shaking. 16 μl of cell lysate was transferred to a 384-well plate (Greiner) and 4 μl / well of pre-mixed antibodies (Cisbio 64AERPEH) was added. The plates were incubated overnight at room temperature and then the HTRF signal was read in a Tecan Spark multimode plate reader. Data were analyzed using a 4-parameter logistic model to calculate IC50values. The results of the phosphorylation-ERK1 / 2 (THR202 / TYR204) HTRF test are shown in the following table:
