Abstract
Description
[Technical Field]
[0001] Technical field This disclosure relates to 3-{4-[(2R)-2-aminopropoxy]phenyl}-N-[(1R)-1-(3-fluorophenyl The present invention relates to the crystalline forms of ethyl[1,2-b]pyridazine-6-amine and its salts, as well as to methods for preparing and using such crystalline forms. [Background technology]
[0002] background 3-{4-[(2R)-2-aminopropoxy]phenyl}-N-[(1R)-1-(3-fluorophenyl)ethyl]-imidazo[1,2-b]pyridazine-6-amine (compound 1) is a known ROS1 receptor tyrosine kinase. It is an inhibitor and a neurotrophic tyrosine receptor kinase (NTRK) inhibitor, with the following chemical structure: [ka] It has.
[0003] The ROS1 gene encodes a receptor tyrosine kinase, which was discovered as a human ortholog of v-ros, an oncogene product of the aerosarcoma virus UR2 (University of Rochester oncovirus 2). The ROS1 fusion gene, obtained through chromosomal rearrangement involving the ROS1 gene and subsequent fusion of the ROS1 gene with another gene, was discovered in the glioblastoma cell line U118MG. In U118MG cells, the gene encoding the Golgi protein FIG (fused in glioblastoma) fuses with the ROS1 gene to form a gene encoding the FIG-ROS1 fusion protein. The fusion between FIG and ROS1 constitutively activates the ROS1 kinase enzyme activity. By undergoing structural changes, the FIG-ROS1 fusion protein possesses cell transformation and tumorigenic activity mediated by the activation of the ROS1 signaling pathway, including STAT3, ERK, and SHP2.
[0004] Chromosomal translocations of the ROS1 gene were also observed in the non-small cell lung cancer cell line HCC78 and in clinical lung cancer specimens. Identified. The fusion gene of the SLC34A2 gene and the ROS1 gene has been reported in HCC78 cells, and the transmembrane protein coding CD74-ROS1 fusion gene of the CD74 gene and the ROS1 gene. This gene has been reported in specimens from non-small cell lung cancer patients. It is a fusion gene of the FIG gene and the ROS1 gene. The gene was found in two of the 23 patient samples from bile duct cancer patients.
[0005] Large-scale screening of patient samples using FISH (fluorescence in situ hybridization) identified fusion genes of the ROS1 gene containing SDC, CD74, EZR, SLC34A2, LRIG3, or TPM3. One of the ROS1 fusion genes, SDC-ROS1, CD74-ROS1, EZR-ROS1, SLC34A2-ROS1, LRIG3-ROS1, or TPM3-ROS1, was detected in 13 out of 1476 non-small cell lung cancer patient samples.
[0006] Similarly, a large-scale screening of non-small cell lung cancer patient samples using FISH revealed the ROS1 fusion gene in 18 out of 1073 cases. Furthermore, analysis of patient samples showed that the ROS1 gene is highly expressed in brain tumors.
[0007] ROS1 has been shown to be activated in cancers expressing ROS1 fusion genes (e.g., non-small cell lung cancer, cholangiocarcinoma, or brain tumors). Therefore, drugs that inhibit ROS1 kinase activity can block downstream ROS1 pathways that contribute to tumor growth and tumor cell survival, namely STAT3, ERK, and SHP2. For this reason, ROS1 kinase inhibitors are expected to be useful as therapeutic agents for cancer. Compounds such as crizotinib, TAE684, pyrazole derivatives, and aminopyrazine derivatives have been reported to have inhibitory effects on ROS1 kinase enzyme activity.
[0008] Neurotrophic tyrosine receptor kinases, also known as tropomyosin-related kinases (Trk), These are high-affinity receptors activated by soluble growth factors called neurotrophins (NTs). The NTRK receptor family has three members: NTRK1 (also known as TrkA), NTRK2 (also known as TrkB), and NTRK3 (also known as TrkC).
[0009] NT includes several proteins such as: nerve growth factor (NGF) which activates NTRK1, and NTRK2 Examples include brain-derived neurotrophic factor (BDNF) and NT-4 / 5, which activate NTRK, and NT3, which activates NTRK3. Each NTRK receptor contains an extracellular domain (ligand-binding site), a transmembrane domain, and an intracellular domain (including a kinase domain). Upon binding to a ligand, each kinase catalyzes autophosphorylation, which then activates downstream signaling pathways.
[0010] NTRKs are widely expressed in nerve tissue during their developmental stages and play a crucial role in the maintenance and survival of these cells. Previous studies have shown that NTRKs play an important role in both the development and function of the nervous system.
[0011] Many references state that NTRK signaling is associated with cancer. For example, NTRK is present at low levels in non-nervous regions of adult humans, and NTRK expression is increased in the later stages of prostate cancer. In normal prostate tissue and early-stage androgen-dependent prostate tumors, NTRK1 is expressed only at low or undetectable levels, while neither NTRK2 nor NTRK3 are expressed. However, in later-stage androgen-independent prostate tumors... In cancer, all isoforms of the NTRK receptor and their ligands are overexpressed. Evidence indicates that these late-stage prostate cancer cells depend on NTRK for their tumor survival. Therefore, NTRK inhibitors may induce apoptosis in androgen-independent prostate cancer. Recent references also show that NTRK overexpression, activation, amplification, fusion gene formation, or mutation is associated with neuroblastoma, secretory breast cancer, colorectal cancer, ovarian cancer, head and neck cancer, pancreatic cancer, and melanoma.
[0012] CEP-751, CEP-701, indolocarbazole compounds, oxindo Selective NTRK tyrosine kinase inhibitors have been reported, including tetramine compounds, pyrazolyl condensed ring compounds, isothiazole compounds, and various other compounds. [Overview of the Initiative]

For example, the weight increase of crystalline forms A and D of compound 1-adipate at 80% RH is These are 0.235% and 0.34%, respectively. As another example, the weight increases of crystalline forms A, B, and C of compound 1 free base at 80% RH are 0.1%, 0.005%, and 0.107%, respectively. Hygroscopicity is the same as that of the drug. Hygroscopicity affects the stability of the substance, as well as its flowability and uniformity during the formulation process, thus impacting the quality of the drug product. Hygroscopicity also affects the preparation, storage, and subsequent handling of the drug. Crystalline forms with low hygroscopicity do not require specific storage conditions, reducing the costs of storage and quality control.
[0034] In some embodiments, the specific crystalline forms described herein have excellent physical stability. For example, crystalline form A of compound 1 adipate remains crystallinely unchanged for at least two weeks when stored in air under conditions of 40°C / 75%RH. Excellent physical stability The properties of the drug product are extremely important in drug discovery. During the manufacture of the drug product, (storage, transport and formulation) There are many processes (including those involved in storage and transportation). These processes often involve storage and transportation. The drug is subjected to stress conditions that can be caused by collisions between drug substances, the wet granulation process in drug manufacturing, seasonal and local climatic differences, and weather factors.
