Definitions
- the invention belongs to the technical field of medicine, and in particular relates to a substituted macrocyclic compound of pyrazolo[1,5-a]pyrimidine and a composition comprising the same and use thereof. More particularly, the present invention relates to certain deuterium-substituted methyl 9-difluoro-15-aza -2,11,16,20,21,24- six dioxolane [16.5.2.0 2,6, 0 7, 12, 0 21, 25] pentacosa-1 (24), 7,9,11,18 (25), 19,22- seven-en-17-one compounds and stereoisomers, such as deuterium substituted
- the compounds exhibit Trk family protein tyrosine kinase inhibition and are useful in the treatment of pain, inflammation, cancer and certain infectious diseases, and these oxime substituted compounds have superior pharmacokinetic properties.
- Trk is a high-affinity receptor tyrosine kinase that is activated by a group of soluble growth factors that are neurotrophic factors (NT).
- the Trk receptor family has three members, namely TrkA, TrkB and TrkC.
- the neurotrophic factors are (1) nerve growth factor (NGF) that activates TrkA, (2) brain-derived neurotrophic factor (BDNF) and NT-4/5, which activate TrkB, and (3) TrkC that activates TrkC.
- NGF nerve growth factor
- BDNF brain-derived neurotrophic factor
- TrkC that activates TrkC.
- Trk is widely expressed in neuronal tissues and is involved in the maintenance, signaling and survival of neuronal cells.
- Trk overexpression, activation, amplification and/or mutations are associated with many cancers including neuroblastoma, ovarian cancer, breast cancer, prostate cancer, pancreatic cancer, multiple myeloma, astrocytoma and Neuroblastoma, glioma, melanoma, thyroid cancer, pancreatic cancer, large cell neuroendocrine tumor and colorectal cancer.
- inhibitors of the Trk/neurotrophin pathway have been shown to be effective in a variety of preclinical animal models for the treatment of pain and inflammatory diseases.
- the neurotrophin/Trk pathway has also been implicated in the pathogenesis of neurodegenerative diseases, including multiple sclerosis, Parkinson's disease, and Alzheimer's disease.
- the modulating neurotrophic factor/Trk pathway can be used to treat these and related diseases.
- TrkA receptor is critical for the disease process in the parasitic infection of Trypanosoma cruzi (Chagas disease) in human hosts. Therefore, TrkA inhibitors can be used to treat Chagas disease and related protozoal infections.
- Trk inhibitors can also be used to treat diseases associated with imbalances in bone remodeling, such as osteoporosis, rheumatoid arthritis, and bone metastasis.
- Bone metastases are a common complication of cancer, up to 70% in patients with advanced breast or prostate cancer and about 15 in patients with lung, colon, stomach, bladder, uterine, rectal, thyroid or kidney cancer Up to 30%. Bone metastasis can cause severe pain, pathological fractures, life-threatening hypercalcemia, spinal cord compression and other neuro-compression syndromes. For these reasons, bone metastases are costly and serious cancer complications. Therefore, an agent that can induce apoptosis of proliferating bone cells is very advantageous.
- TrkA receptor and TrkC receptor have been observed in the osteogenic region of the fractured mouse model. In addition, almost all osteoblast apoptosis agents are very advantageous. Expression of the TrkA receptor and TrkC receptor has been observed in the osteogenic region of the fractured mouse model. In addition, localization of NGF was observed in almost all osteoblasts. Recently, it was demonstrated that pan-Trk inhibitors in human hFOB osteoblasts inhibit tyrosine signaling activated by neurotrophic factors that bind to all three Trk receptors. This data supports the theory of using Trk inhibitors to treat bone remodeling diseases, such as bone metastases in cancer patients.
- Larotrectinib (LOXO-101) is the first generation of Trk inhibitor developed by Loxo Oncology.
- LOXO-101 began treating the first patient in March 2015; on July 13, 2016, it was awarded the breakthrough drug qualification by the FDA for Inoperable resection or metastatic solid tumors in adults and children with positive Trk fusion gene mutations; key enrollment completed in February 2017.
- the Trk gene of cancer patients may produce some mutations (such as NTRK1 G595R, NTRK3 G623R and other mutations), resulting in drug resistance.
- LOXO-195 (chemical name (6R, 15R) -9- fluoro-15-methylerythromycin -2,11,16,20,21,24- dioxolane hexaazatetracyclo [16.5.2.0 2,6, 0 7, 12, 0 21, 25] pentacosa-1 (24), 7,9,11,18 (25), 19,22- heptaen-17-one, having the following structure formula) are developed by the company Loxo Oncology
- the second-generation Trk inhibitor can effectively resist the drug resistance produced by Larotrectinib.
- ADME ulcerative co-oxidative desorption, distribution, metabolism, and/or excretion
- Many of the drugs currently on the market also limit their range of applications due to poor ADME properties.
- the rapid metabolism of drugs can lead to the inability of many drugs that could be effectively treated to treat diseases because they are too quickly removed from the body.
- Frequent or high-dose medications may solve the problem of rapid drug clearance, but this approach can lead to problems such as poor patient compliance, side effects caused by high-dose medications, and increased treatment costs.
- rapidly metabolizing drugs may also expose patients to undesirable toxic or reactive metabolites.
- the present invention discloses a novel hydrazine-substituted 9-fluoro-15-methyl-2,11,16,20,21,24-hexaazapentene ring [16.5.2.0 2,6 , 0 7,12 ,0 21,25 ]dipentadecane-1(24), 7,9,11,18(25),19,22-hepten-17-one and its stereoisomers (for example, Compound ⁇ , compound ⁇ -a and compound ⁇ -b, structural formula below), and compositions and uses thereof, have better Trk kinase inhibitory activity, lower side effects, better pharmacodynamics/pharmacokinetics Performance, can be used to treat Trk kinase mediated diseases.

7,12,0
21,25]二十五烷-1(24),7,9,11,18(25),19,22-七烯-17-酮的化合物及其立体异构体,这些氘取代的化合物显示Trk家族蛋白酪氨酸激酶抑制,且可用于治疗疼痛、炎症、癌症和某些传染病的用途,且这些氘取代的化合物具有更优良的药代动力学性质。
Trk是由成为神经营养因子(NT)的一组可溶性生长因子激活的高亲和性受体酪氨酸激酶。Trk受体家族具有3个成员,即TrkA、TrkB和TrkC。神经营养因子中有(1)可激活TrkA的神经生长因子(NGF),(2)可激活TrkB的脑源性神经营养因子(BDNF)和NT-4/5,和(3)可激活TrkC的NT3。Trk在神经元组织中广泛表达且与神经元细胞的维持、信号传导和存活有关。
文献也显示Trk的过度表达、激活、扩增和/或突变与许多癌症有关,该癌症包括神经细胞瘤、卵巢癌、乳腺癌、前列腺癌、胰腺癌、多发性骨髓瘤、星形细胞瘤与成神经管细胞瘤、神经胶质瘤、黑素瘤、甲状腺癌、胰腺癌、大细胞神经内分泌瘤和结肠直肠癌。此外,已证明Trk/神经营养因子途径的抑制剂在治疗疼痛和炎性疾病的多种临床前动物模型中有效。
神经营养因子/Trk途径,特别是BDNF/TrkB途径也已经牵涉神经变性疾病的病因,该疾病包括多发性硬化、帕金森金氏(Parkinson’s disease)和阿尔茨海默病(Alzheimer’s disease)。调节神经营养因子/Trk途径可用于治疗这些疾病和相关疾病。
据认为TrkA受体对于克氏锥虫(查加斯氏病)在人类宿主中的寄生虫感染中的疾病过程至关重要。因此,TrkA抑制剂可用于治疗查加斯氏病和有关的原生动物感染。
Trk抑制剂也可用于治疗与骨重建调节失衡有关的疾病,例如骨质疏松症、类风湿性关节炎和骨转移。骨转移是癌症的常见的并发症,在晚期乳腺癌或前列腺癌患者中高达70%和在肺癌、结肠癌、胃癌、膀胱癌、子宫癌、直肠癌、甲状腺癌或肾癌患者中为约15至30%。蓉骨性转移可造成严重的疼痛、病理性骨折、危及生命的高钙血症、脊髓压迫症和其它神经压迫综合征。出于这些原因,骨 转移是花费高的严重的癌症并发症。因此,可诱导增殖性骨细胞凋亡的药剂是非常有优势的。已在骨折的小鼠模型的成骨区域中观察到TrkA受体和TrkC受体的表达。另外,在几乎所有的成骨细胞凋亡的药剂是非常有优势的。已在骨折的小鼠模型的成骨区域中观察到TrkA受体和TrkC受体的表达。另外,在几乎所有的成骨细胞中均观察到NGF的定位。最近,证明在人类hFOB成骨细胞中pan-Trk抑制剂可抑制由与所有3个Trk受体结合的神经营养因子所激活的酪氨酸信号传导。该数据支持使用Trk抑制剂治疗骨重建疾病(例如癌症患者中的骨转移)的理论。
Larotrectinib(LOXO-101)由Loxo Oncology公司研发的第一代Trk抑制剂,LOXO-101在2015年3月开始治疗第一名患者;2016年7月13日被FDA授予突破性药物资格,用于Trk融合基因突变阳性的成人及儿童的不可手术切除或转移性实体瘤;2017年2月完成关键入组。但是在接受Larotrectinib抑制剂治疗后,癌症患者的Trk基因可能产生一些突变(如NTRK1 G595R,NTRK3 G623R等位点的突变),导致耐药性的产生。LOXO-195(化学名称为(6R,15R)-9-氟-15-甲基-2,11,16,20,21,24-六氮杂戊环[16.5.2.0
2,6,0
7,12,0
21,25]二十五烷-1(24),7,9,11,18(25),19,22-七烯-17-酮,具有如下结构式)是Loxo Oncology公司研发的第二代Trk抑制剂,能有效抵制Larotrectinib产生的耐药性。已证明一名结直肠癌的成年患者和纤维肉瘤的儿童患者产生Larotrectinib耐药性后,接受LOXO-195来治疗能够延长Trk基因突变患者的病程,患者都有缓释效应,且几乎没有副作用(Drilon.A.,et al.,Cancer Discov.2017,7(9),1-10)。目前,FDA已经正式批准LOXO-195作为实验性新药,开展临床I期和II期试验。
已知较差的吸收、分布、代谢和/或排泄(ADME)性质是导致许多候选药物临床试验失败的主要原因。当前上市的许多药物也由于较差的ADME性质限制了它们的应用范围。药物的快速代谢会导致许多本来可以高效治疗疾病的药物由于过快的从体内代谢清除掉而难以成药。频繁或高剂量服药虽然有可能解决药物快速清除的问题,但该方法会带来诸如病人依从性差、高剂量服药引起的副作用及治疗成本上升等问题。另外,快速代谢的药物也可能会使患者暴露于不良的毒性或反应性代谢物中。
虽然LOXO-195作为Trk抑制剂能有效治疗多种癌症等病症,但是发现具有治疗癌症等病症且 具有很好的口服生物利用度且有成药性的新型化合物还是具有挑战性的工作。因此,本领域仍需开发对适用作治疗剂的Trk激酶介导疾病具有选择性抑制活性或更好地药效学/药代动力学的化合物,本发明提供了这样的化合物。
