Abstract

本发明涉及一种通式(1)所示的化合物及其制备方法，及如通式(1)所示的化合物或其各异构体、各晶型、药学上可接受的盐、水合物或溶剂合物作为HPK1抑制剂的用途。本发明化合物可用于制备治疗或者预防由HPK1介导的相关疾病。

Description

HPK1抑制剂及其制备方法和用途
本申请要求申请日为2020年4月20日的中国专利申请CN2020103138714的优先权。本申请引用上述中国专利申请的全文。
技术领域
本发明属涉及药物化学领域，更具体而言，涉及一类新型HPK1抑制剂化合物，及其制备方法和该类化合物用于制备治疗或者预防由HPK1介导的相关疾病。
背景技术
造血祖细胞激酶1(hematopoietic progenitor kinase1，HPK1)为造血祖细胞中克隆出来的丝氨酸/苏氨酸蛋白激酶，属于哺乳动物Ste-20相关蛋白激酶MAP4K家族成员之一，其它成员包括MAP4K2/GCK、MAP4K3/GLK、MAP4K4/HGK、MAP4K5/KHS和MAP4K6/MINK[Mol.Cell Biol.，1999，19(2)：1359-1368.]。HPK1主要在造血祖细胞、T细胞、B细胞、NK细胞、免疫树突细胞、巨噬细胞和肥大细胞等造血免疫相关的细胞中表达[J.Biol.Chem.，2004，279(47)：49551-49561.]。
HPK1在T，B细胞受体以及树突细胞活化时激活，反馈抑制T，B细胞受体活化，树突细胞抗原递呈等多种免疫响应。HPK1与许多接头蛋白，如SLP-76家族、CARD11、HIS、HIP-55、GRB2家族、LAT、CRK家族等相互作用，发挥功能。在T、B细胞受体活化时，HPK1磷酸化SLP-76家族蛋白，调节SLP-76蛋白复合物的活性，从而对T细胞受体，B细胞受体信号转导通路进行负向调节。与HPK1的免疫抑制作用相符，HPK1缺失的T细胞和树突细胞活力增强，对肿瘤的杀伤力更强。因此，抑制HPK1增强肿瘤的免疫反应，而HPK1作为T细胞介导的免疫反应的调节机制，成为新的免疫抗肿瘤的研发热点。HPK1抑制剂在治疗恶性实体瘤或者血液癌(如急性髓性白血病、膀胱上皮癌、乳腺癌、结肠癌、肺癌、胰腺癌、黑色素瘤)，以及HPK1相关的免疫性疾病中具有潜在的应用价值。
目前针对HPK1靶点尚未有药物上市，为了更好的满足巨大的临床需求，开发调节HPK1活性的新化合物将为治疗相关疾病提供新的方向。

“药学上可接受”这里指一种物质，如载体或稀释液，不会使化合物的生物活性或性质消失，且相对无毒，如，给予个体某物质，不会引起不想要的生物影响或以有害的方式与 任何其含有的组分相互作用。
术语“药学上可接受的盐”指一种化合物的存在形式，该形式不会引起对给药有机体的重要的刺激，且不会使化合物的生物活性和性质消失。在某些具体方面，药学上可接受的盐是通过式(1)化合物与酸反应获得，如盐酸、氢溴酸、氢氟酸、硫酸、磷酸、硝酸、磷酸等无机酸，甲酸、乙酸、丙酸、草酸、三氟乙酸、丙二酸、琥珀酸、富马酸、马来酸、乳酸、苹果酸、酒石酸、柠檬酸、苦味酸、甲磺酸、苯磺酸、对甲苯磺酸等有机酸以及天冬氨酸、谷氨酸等酸性氨基酸。
应理解药学上可接受的盐的参考包括溶剂添加形式或结晶形式，尤其是溶剂化物或多晶型。溶剂化物含有化学计量或非化学计量的溶剂，且是在与药学上可接受溶剂如水，乙醇等，结晶化过程中选择性形成的。当溶剂是水时形成水合物，或当溶剂是乙醇时形成醇化物。式(1)化合物的溶剂化物按照本文所述的方法，很方便的制得或形成。举例说明，式(1)化合物的水合物从水/有机溶剂的混合溶剂中重结晶而方便的制得，使用的有机溶剂包括但不限于，四氢呋喃、丙酮、乙醇或甲醇。此外，在此提到的化合物能够以非溶剂化和溶剂化形式存在。总之，对于在此提供的化合物和方法为目的，溶剂化形式被认为相当于非溶剂化形式。

在另一个方面，式(1)化合物存在手性中心，并因此以消旋体、外消旋混合物、单一对映体、非对映异构体化合物和单一非对映体的形式、和顺反异构体的形式出现。每个这种手性中心将独立地产生两个旋光异构体，并且所有可能的旋光异构体和非对映体混合物以及纯或部分纯的化合物包括在本发明的范围之内。本发明意味着包括这些化合物的所有这种异构形式。
本发明的化合物可以在一个或多个构成该化合物的原子上包含非天然比例的原子同位素。例如，可用放射性同位素标记化合物，比如氚( 3H)、碘-125( 125I)和C-14( 14C)。又例如，可用重氢取代氢原子形成氘代化合物，氘与碳构成的键比普通氢和碳构成的键更坚固，相比于未氘代药物，通常氘代药物具有降低毒副作用、增加药物稳定性、增强疗效、延长药物体内半衰期等优势。本发明的化合物的所有同位素组成的变换，无论放射性与否，都包含在本发明的范围之内。
