技术领域
本发明涉及一类新的吲哚啉类化合物，具体涉及式(I)化合物及其药学上可接受的盐在制备治疗相关疾病药物中的应用。
背景技术
PD-1全称是程序性死亡受体1，英文名字为programmed death 1，是一种重要的免疫抑制分子，为CD28超家族成员。PD-L1全称是程序性死亡受体-配体1，英文名字programmed cell death-Ligand 1，是一种40kD的跨膜蛋白，由CD274基因编码。PD-L1可被诱导表达于T细胞、B细胞、树突细胞、巨噬细胞、间充质干细胞、骨髓来源的肥大细胞和非造血细胞的表面上，在干扰素及其他炎症因子刺激应答的肿瘤组织和其他组织中都可能会迅速上调。PD-1/PD-L1通路激活后，在癌症、妊娠、组织移植以及自身免疫病中抑制免疫系统。此外，PD-L1还能与CD80结合，竞争性抑制CD80与配体结合的T细胞激活通路，成为PD-L1抑制T细胞活性的另一机制。
在正常情况下，PD-1/PD-L1信号通路可以放置免疫系统对组织的过度攻击而诱导的过度炎症、自身免疫疾病。在非正常情况下，如肿瘤组织及慢性HBV感染组织内，存在PD-L1过度表达的情况。PD-1/PD-L1的过表达及信号通路激活抑制了功能性T细胞的活化及增殖，抑制抗肿瘤免疫反应，使得免疫系统对肿瘤的发展失去抑制作用，进而加速肿瘤的发展与恶化。针对该通路已经有多种药物获批。其中，PD-L1单克隆抗体，如Atezolizumab已经在尿路上皮癌及非小细胞肺癌适应证尚获批，在肿瘤相关适应证上还有更多临床研究在进行中。但是，相比小分子，大分子药物在诸如组织渗透、药代动力学性质、费用及使用方式上都存在明显的缺点，因此，在PD-1/PD-L1信号通路上开发小分子药物依旧是未被满足的临床需求，具备广阔的市场前景。
目前，百施美-施贵宝公司、Incyte制药公司及Gilead制药公司均有小分子PD-1/PD-L1抑制剂报道。Incyte制药公司的专利WO2018119224报道了该系列化合物展示了较好的细胞活性，并将化合物INCB086550推上了临床。尽管如此，上述小分子化合物系列在化合物的药理性质(体外活性和体内抑制肿瘤生长活性等)，还有很大的改善空间；因此，在PD-1/PD-L1信号通路小分子抑制剂的开发上面，提示还有更大的空间及前景。
