Definitions
- This application belongs to the field of chemistry and medicine, and specifically relates to an ERK1/2 protein kinase inhibitor and its use.
- Extracellular signal-regulated kinase is a widely expressed protein serine/threonine kinase and one of the important subfamily of the mitogen-activated protein kinase (MAPK) family.
- the MAPK pathway is an evolutionary conserved cell signaling pathway that regulates various cellular processes, including cell cycle progression, cell migration, cell survival, differentiation, metabolism, proliferation, and transcription.
- the ERK/MAPK signaling pathway responds to extracellular stimulation of the cell surface receptor tyrosine kinase (RTK).
- RAS GTPases K-RAS, N-RAS, and H-RAS
- Activated RAS activates the kinase activity of RAF (A-RAF, B-RAF and C-RAF) by phosphorylating the downstream RAF effector protein, which in turn phosphorylates and activates the dual-specific kinase MEK (MEK1/2). Then, the activated MEK phosphorylates and activates ERK1/2.
- Phosphorylation activated ERK1/2 is translocated from the cytoplasm to the nucleus, and then mediates the transcriptional activation of Elk-1, ATF, NF- ⁇ B, Ap-1, c-fos and c-Jun, and participates in a variety of biological reactions , Including cell proliferation and differentiation, cell morphology maintenance, cytoskeleton construction, cell apoptosis and cell malignancy, etc.
- ERK and its signal pathway play a role in mediating and amplifying signals in the process of tumor invasion and metastasis.
- abnormal activation of multiple protein mutations in the ERK signal pathway can be found, which ultimately leads to the excessive activation of ERK kinase activity.
- KRAS is the most common mutant subtype, mutated in 22% of tumors. KRAS mutations are especially common in pancreatic cancer (70-90%), non-small cell lung cancer (10-20%), and colorectal cancer (25-35%) (Neuzilletetal., 2014. Pharmacol. Ther.
- N-RAS mutations and H-RAS mutations occur in 8% and 3% of cancers, respectively (Prior et al., Cancer Res. 2012; 72(10); 2457-2467). It is worth noting that it is reported that 15-20% of melanoma cases have activated N-RAS mutations. In addition, 8% of all tumors have B-RAF mutations. The majority of B-RAF mutations are B-RAF V600E mutations. This mutation is found in melanoma (50-60%) and papillary thyroid cancer (40-60%). %), colorectal cancer (5-10%) and non-small cell lung cancer (3-5%) are especially prevalent (Neuzillet et al., 2014. Pharmacol. Ther.
- B-RAF can be continuously activated without RAS phosphorylation activation.
- anti-tumor drugs that specifically target the B-RAF V600E mutation have been marketed, and have shown good curative effects in diseases such as melanoma.
- ERK the key kinase at the most downstream of the entire MAPK signaling pathway.
- all drugs targeting B-RAF V600E mutations currently on the market have developed severe drug resistance within less than a year of treatment.
- a large number of clinical studies have shown that, in addition to common drug resistance mutations, abnormal reactivation of ERK kinase activity is an important mechanism for drug resistance.
- ERK1/2 inhibitors with rapid clinical progress such as Ulixertinib (Phase II), ASTX-029, etc.
- Ulixertinib Phase II
- ASTX-029 ASTX-029
- ASTX-029 also has a strong inhibitory activity on the proliferation of B-RAF wild-type tumor cells, which in turn may show strong clinical toxicity.

Abstract
本申请提供一种由式(Ⅰ)表示的化合物,或其异构体或药学上可接受的盐,以及其用于制备ERK1/2介导的疾病药物的用途。
Description
本申请属于化学医药领域,具体涉及一种ERK1/2蛋白激酶抑制剂及其用途。
细胞外信号调节激酶(ERK1/2)是广泛表达的蛋白丝氨酸/苏氨酸激酶,是丝裂原活化蛋白激酶(MAPK)家族的重要亚族之一。MAPK通路是进化保守的细胞信号通路,调节各种细胞过程,包括细胞周期进程、细胞迁移、细胞生存、分化、代谢、增殖和转录。ERK/MAPK信号通路对细胞表面受体酪氨酸激酶(RTK)的细胞外刺激做出响应。激活RTK时,RAS GTP酶(K-RAS、N-RAS和H-RAS)从未活化GDP-结合状态转化为活化的GTP-结合状态。活化的RAS通过磷酸化下游RAF effector蛋白,从而激活RAF(A-RAF、B-RAF和C-RAF)的激酶活性,它们转而又磷酸化,激活双特异性激酶MEK(MEK1/2)。然后,活化的MEK磷酸化,并激活ERK1/2。磷酸化激活的ERK1/2由胞质转位到核内,进而介导Elk-1,ATF,NF-κB,Ap-1,c-fos和c-Jun的转录活化,参与多种生物学反应,包括细胞增殖与分化、细胞形态维持、细胞骨架的构建、细胞凋亡和细胞的恶变等。
ERK及其信号途径在肿瘤侵袭和转移过程中起中介和放大信号的作用,在许多人类的癌症中都可以发现ERK信号通路上多个蛋白突变引起的异常激活而最终导致ERK激酶活性的过度激活。大约30%的人类癌症包含活化RAS突变(Roberts and Der,Oncogene.2007;26:3291-3310)。KRAS是最常见的突变亚型,在22%的肿瘤中突变。KRAS突变在胰腺癌(70~90%)、非小细胞肺癌(10~20%)和结肠直肠癌(25~35%)中尤其普遍(Neuzilletetal.,2014.Pharmacol.Ther.141;160-171)。分别在8%和3%的癌症中出现N-RAS突变和H-RAS突变(Prior et al.,Cancer Res.2012;72(10);2457-2467)。值得指出的是,据报道,15-20%的黑色素瘤病例存在活化N-RAS突变。此外,所有肿瘤中有8%出现B-RAF突变,B-RAF绝大部分突变形式为B-RAF
V600E突变,这种突变在黑色素瘤(50-60%)、乳头状甲状腺癌(40~60%)、结肠直肠癌(5~10%)和非小细胞肺癌(3~5%)中尤其普遍存在(Neuzillet et al.,2014.Pharmacol.Ther.141;160-171),这使得B-RAF可以不需要RAS磷酸化激活而处于持续活化的状态。目前已有多个特异性靶向B-RAF
V600E突变的抗肿瘤药物上市,在黑色素瘤等疾病领域表现出良好的疗效。然而目前为止尚无针对作为整个MAPK信号通路最下游的关键激酶ERK的特异性靶向药物上市。另外一方面,目前已经上市的所有靶向B-RAF
V600E突变药物均在治疗不到一年的时间内出现了较为严重的的耐药性。大量临床研究表明,除常见的耐药突变以外,ERK激酶活性的异常重新激活是此类药物耐药的重要机理。因此开发新型特异性ERK抑制剂既可以作为一种新型抗肿瘤药物,与此同时又可以作为多种B-RAF
V600E突变抑制剂药物耐药后的二线药物,在抗肿瘤治疗中有着非常重要的临床和市场价值。
临床进展较快的ERK1/2抑制剂如Ulixertinib(Phase II)、ASTX-029等已显示出良好的生物学活性。然而Ulixertinib在药物代谢方面的缺陷导致较高的临床剂量以及更为频繁的给药方式对其进一步临床开发带来了较大限制。而ASTX-029对B-RAF野生型肿瘤细胞增殖的抑制活性也较强,进而有可能在临床上表现出较强的毒性。
