Description

吲唑类化合物的新用途 技术领域
本申请涉及一种吲唑类化合物的新用途。更具体地，本发明涉及吲唑类化合物在预防或治疗携带TRKA/B/C融合基因和/或突变的激酶活性相关的疾病中的用途。
背景技术
原肌球蛋白相关激酶(Tropomyosin-related kinase)，统称为TrK家族蛋白，是一类神经生长因子受体，由高度同源性的原肌球蛋白相关激酶A(TRKA)、原肌球蛋白相关激酶B(TRKB)、原肌球蛋白相关激酶C(TRKC)三种蛋白组成，分别由相应的NTRK1、NTRK2和NTRK3基因编码。1982年，科学家Mariano Barbacid和他的同事在结直肠癌中发现了NTRK1基因，随后确定其为致癌基因。TRK激酶被认为与神经元细胞的生长、分化以及凋亡有关，然而，近几十年的研究结果表明，TRK激酶的部分缺失、发生融合以及过表达以后与多种肿瘤如***状甲状腺癌、胰腺癌、结直肠癌、乳癌、黑色素瘤、非小细胞肺癌、急性髓性白血病、成神经细胞瘤等的发生发展、侵袭转移和恶化等有着密切关系(Emiliano Cocco1,Maurizio Scaltriti1,Alexander Drilon，NTRK fusion-positive cancers and TRK inhibitor therapy.Nat.Rev.Clin.Oncol.2018,15,731-747.)。
通常TRK激酶与相应的配体紧密结合，如神经生长因子NGF与TRKA，脑源性神经营养因子BDNF或者神经营养因子NT-4与TRKB，神经营养因子NT-3与TRKC。NT-3可以结合并激活三种TRK蛋白，但是它与TRKC的结合紧密程度高于TRKA和TRKB。当配体与TRK激酶结合以后，TRK激酶通过二聚而发生自磷酸化，从而激活下游的信号通路，主要包括RAS/RAF/MEK/ERK、PI3K/AKT以及PLCγ信号通路。因此，当TRK功能失调导致下游通道被过度激活时，可能会导致上述癌症的发生。
已报道的TRK激酶抑制剂用于治疗多种癌症以及疼痛。第一代TRK激酶抑制剂用药以后患者会出现耐药突变，而临床上大部分小分子抑制剂主要是第一代TRK激酶抑制剂。为了解决获得性耐药的问题， 拜耳和LOXO Oncology公司合作研发的第二点激酶抑制剂LOXO-195(NCT03215511)，目前在接受Larotrectinib治疗产生耐药突变的患者上进行治疗，并取得一定的治疗作用。例如在临床I期和II期的NTRK阳性的患者，包括非小细胞肺癌、结直肠癌、胆管癌、胰腺癌、甲状腺癌、肉瘤、胃肠间质瘤等多名患者在接受Larotrectinib治疗后，发现了TRKs突变，主要包括溶剂前沿突变(如TRKA/G595R、TRKC/G623R)、xDFG突变(如TRKA/G667C、TRKA/G667S、TRKC/G696A、TRKC/G696C)以及Gatekeeper突变(TRKA/F589L、TRKC/F617L)等，这些新出现的突变能让Entrectinib和Larotrectinib无法与激酶结合，从而产生耐药。
目前急需开发出能够克服第一代TRK抑制剂Larotrectinib临床上的耐药突变的新型药物，用于治疗与例如TRKA的F589L、V573M、G667C、G667S、G667A突变，TRKB的F633L、G709C突变，和/或TRKC的F617L、G696A、G696C突变相关的疾病，并将这些化合物应用于与这些突变相关的癌症或者其它相关疾病的治疗中。
