技术背景
泛素-蛋白酶体途径(Ubiquitin-Proteasome Pathway,简称UPP)是细胞内蛋白质系统降解的主要途径,并参与许多生理上重要的细胞进程,包括信号转导,免疫应答,未折叠蛋白反应和细胞周期进展。这一途径与心脑血管疾病、癌症及神经系统退行性疾病的发病等都有着重要的关系。蛋白酶体抑制剂已被用于疾病,2003年,首款蛋白酶体抑制剂获批上市。
目前临床上使用的蛋白酶体抑制剂以硼替佐米、卡非佐米、伊沙佐米为代表。其中硼替佐米、卡非佐米为静脉注射给药,需要专业医务工作者实施,不可避免地降低患者的顺从性以及生活质量,且这两个药物在临床应用上分别出现外周神经毒性、心脏毒性以及易耐药等安全性、有效性问题;而伊沙佐米虽为口服制剂,但临床有效性较差,需要与其它药物联用。因此有必要研制开发新的高效低毒的可口服的蛋白酶体抑制剂。
专利CN112384519公开了N-((R)-1-(((R)-1-(1,3,6,2-二氧杂氮杂硼烷-2-基)-3-甲基丁基)氨基)-3-(甲硫基)-1-氧代丙-2-基)-2,5-二氯苯甲酰胺作为一种蛋白酶体抑制剂,用于治疗实体瘤和血液瘤,其结构如下式Ⅰ所示。
