Definitions
- the present invention relates to a series of azaquinazoline ring derivatives and uses thereof, and in particular to compounds represented by formula I and pharmaceutically acceptable salts thereof.
- the Cot (Osaka thyroid carcinoma) protein is a serine/threonine kinase that is a member of the MAP kinase kinase kinase (MAP3K) family. It is also known as “TPL2" (tumor progression locus), "MAP3K8” (mitogen-activated protein kinase kinase kinase 8) or "EST" (Ewing sarcoma transformant). Cot was originally discovered as an oncogene in human thyroid cancer cell lines and has since been shown to play an important role in regulating inflammatory pathways.
- Cot is located downstream of receptors such as TNF- ⁇ R, IL-1R, and TLR, and promotes the production and signal transduction of inflammatory factors such as TNF- ⁇ and IL-1 ⁇ by activating the MEK-ERK pathway.
- TNF- ⁇ is a proinflammatory cytokine and plays an important role in immune-related diseases such as rheumatoid arthritis (RA), multiple sclerosis (MS), inflammatory bowel disease (IBD), diabetes, sepsis, psoriasis, and transplant rejection.
- RA rheumatoid arthritis
- MS multiple sclerosis
- IBD inflammatory bowel disease
- diabetes sepsis
- psoriasis psoriasis
- transplant rejection transplant rejection
- Cot can also promote the secretion of inflammatory mediators by neutrophils by activating p38 ⁇ and p38 ⁇ .
- the present invention aims to provide a class of Osaka thyroid carcinoma (Cot) kinase inhibitor compounds with novel structure and excellent inhibitory activity, and also provides the use of the compounds in treating diseases or conditions mediated by Osaka thyroid carcinoma (Cot) kinase.

Abstract
本发明提供了一种氮杂喹唑啉环衍生物及其用途。具体地,本发明提供了式I的化合物,或其药学上可接受的盐,互变异构体、立体异构体、立体异构体混合物或其同位素取代物。所述化合物具有优异的大阪甲状腺癌(Cot)激酶抑制活性,因而可用于预防或治疗大阪甲状腺癌(Cot)激酶介导的疾病或者病症。
Description
本发明涉及一系列氮杂喹唑啉环衍生物及其用途,具体涉及式I所示化合物及其药学上可接受的盐。
Cot(大阪甲状腺癌)蛋白是丝氨酸/苏氨酸激酶,其是MAP激酶激酶激酶(MAP3K)家族的成员。它也被称为“TPL2”(肿瘤进展基因座),“MAP3K8”(促分裂原活化蛋白激酶激酶激酶8)或“EST”(尤因肉瘤转化体)。Cot最初被发现是人类甲状腺癌细胞系中的一种癌基因,后来逐渐发现其在调节炎症通路中的重要作用
Cot位于TNF-αR、IL-1R、TLR等受体下游,通过激活MEK-ERK通路促进TNF-α、IL-1β等炎症因子的产生和信号传导。TNF-α是促炎细胞因子,并且在类风湿性关节炎(RA)、多发性硬化症(MS)、炎性肠病(IBD)、糖尿病、败血症、牛皮癣、移植排斥等免疫相关疾病中起重要作用。Cot还能通过激活p38α和p38δ促进中性粒细胞分泌炎症介质。
因此,本领域急需提供活性更优、代谢稳定性更佳和安全性更好的能够治疗Cot活性相关的疾病的药物。

本发明的某些化合物拥有不对称碳原子(光学中心)或双键;消旋体、非对映体、几何异
构体、区域异构体和单独的异构体(例如,分离的对映体)均应包括在本发明范围内。当本文提供的化合物具有确定的立体化学(表示为R或S,或具有虚线或楔形键指明)时,被本领域技术人员将理解那些化合物为基本上不含其他异构体(例如至少80%,90%,95%,98%,99%和至多100%不含其他异构体)。
本申请中所给出的任何通式或结构也意欲代表为化合物的非标记的形式以及同位素标记的形式。同位素标记的化合物具有由本申请中给出的通式所描述的结构,除了一个或多个原子被具有选择的原子质量或质量数的原子所置换。可以掺入本发明化合物的同位素的实例包括氢、碳、氮、氧、磷、氟和氯的同位素,例如,但不限于2H(氘、D)、3H(氚)、11C、13C、14C、15N、18F、31P、32P、35S、36Cl和125I。本发明包括多种同位素标记的本发明化合物,例如那些放射性同位素如3H、13C和14C掺入其中的化合物。此类同位素标记的化合物可用于代谢研究、反应动力学研究、检测或成像技术,例如核磁共振成像(NMR)、正电子发射断层扫描术(PET)或单光子发射计算机断层成像术(SPECT),包括药物或底物组织分布测定或用于患者的放射性治疗。
本公开还包括其中1至n个(其中n为分子中的氢的数目)连接至碳原子的氢被氘置换的式I化合物的“氘代类似物”。此类化合物显示出对代谢的抗性增强,因此用于增加式I任何化合物的半衰期(当给药至哺乳动物,具体为人时)。此类化合物通过本领域中已知的方法合成,例如,通过使用其中一个或多个氢原子已经被氘置换的起始原料。
氘标记的或取代的本发明的治疗性化合物可以具有改善的DMPK(药物代谢和药代动力学)性质,其涉及分布、代谢和排泄(ADME)。使用较重同位素(例如氘)的取代可以基于较大的代谢稳定性提供一些治疗优势,例如体内半衰期增加、降低的剂量需求和/或治疗指数改善。18F标记的化合物可以用于PET或SPECT研究。同位素标记的本发明化合物及其前药通常通过利用下文中描述的合成路线或实施例和制备中描述的步骤来制备,其中将非同位素标记的试剂替换为便利可得的同位素标记的试剂。可以理解,本申请中的氘可以视为式I化合物的取代基。
此类较重同位素(具体的为氘)的浓度可以由同位素富集因子来定义。在本发明化合物中,任何没有具体指定为特定同位素的原子意味着其代表该原子的任何稳定的同位素。除非另有说明,当某一位置具体指定为“H”或“氢”时,应当理解,该位置为具有其天然丰度同位素组成的氢。因此,在本发明的化合物中,任何被具体指定为氘(D)的原子意味着代表氘。
