Description

一种β-连环蛋白特异性抑制剂的制药用途
技术领域
本发明涉及医药技术领域，具体涉及一种β-连环蛋白特异性抑制剂的制药用途。
背景技术
扩张型心肌病(Dilated cardiomyopathy,DCM)是心力衰竭的第三大常见原因，是一种严重的心脏异质性病理疾病，其病理特征是以心室扩张为特征，并伴有收缩期和舒张期功能障碍。心肌纤维化(Myocardial fibrosis)是细胞外基质重构的病理实体，经常导致心肌硬度增加，DCM中既有反应性(间质和血管周)纤维化，也有修复性(替代性)纤维化，表明炎症和微血管损伤参与了疾病过程。在DCM患者中，心肌纤维化与不良预后和对治疗干预的反应受损有关。提示抗纤维化治疗可能有助于改善病变心脏的心功能。成纤维细胞被认为是心脏纤维化的主要细胞介质，在调节正常心功能和不良心肌重构中发挥重要作用。
Wnt基因同果蝇的体节极性基因无翅wingless(wg)同源，在人和小鼠，Wnt家族编码的19个高度保守的分泌信号分子，是调节细胞生长，分化以及细胞间相互作用的重要调节器。Wnt基因调控的重要信号传导系统即为Wnt通路，其中在经典的Wnt通路中，β-catenin活性的改变，胞浆蓄积，转导胞核激活通路下游靶基因，与调节细胞的生长、分化、增殖、凋亡以及胚胎发育尤为密切。在没有Wnt信号时，胞内游离的β-catenin被Axin和Apc识别后折叠使其磷酸化位点暴露，Cki把β-catenin的Ser45磷酸化后，Gsk3β磷酸化β-catenin的其他三个位点(Thr41，Ser37，Ser33)，β-catenin通过泛素化蛋白酶降解。当Wnt的配体出现时，与细胞膜上的Frizzled受体结合，Frizzled招募Dvl使得Cki不再去磷酸化β-catenin而去磷酸化Lrp5/6，致使β-catenin不被降解，通过核蛋白相互作用进入核内发挥作用。β-catenin高度保守的N-端区域(近130氨基酸)：包含Ser33,Ser37,Thr41,Ser45的磷酸化位点，使β-catenin翻译后保持稳定，且对调节转录活性非常重要，这个部位脱磷酸化的β-catenin称为Active-β-catenin。因此提示我们β-catenin抑制剂有可能能够用于治疗心肌纤维化。
β-catenin-IN-2是一种有效的β-catenin特异性抑制剂，该作用靶点主要是抑制β-catenin的活化，该化合物最早被报道于US20150374662A1用于治疗结肠癌的研究，2021年报道用于胃癌的研究，但是并未见将其用于治疗心脏类疾病。
