  Identification of Potent and Selective Cathepsin S Inhibitors Containing Different Central Cyclic Scaffolds

  摘要：

  Starting from the weakly active dual CatS/K inhibitor 5, structure-based design supported by X-ray analysis led to the discovery of the potent and selective (>50 000-fold vs CatK) cyclopentane derivative 22 by exploiting specific ligand-receptor interactions in the S2 pocket of CatS. Changing the central cyclopentane scaffold to the analogous pyrrolidine derivative 57 decreased the enzyme as well as the cell-based activity significantly by 24- and 69-fold, respectively. The most promising scaffold identified was the readily accessible proline derivative (e.g., 79). This compound, with an appealing ligand efficiency (LE) of 0.47, included additional structural modifications binding in the Si and S3 pockets of CatS, leading to favorable in vitro and in vivo properties. Compound 79 reduced IL-2 production in a transgenic DO10.11 mouse model of antigen presentation in a dose-dependent manner with an ED50 of 5 mg/kg.

  Cathepsin S is a potential target of autoimmune disease. A series of proline derived compounds were synthesized and evaluated as cathepsin S inhibitors. We discovered potent cathepsin S inhibitors through structure–activity relationship studies of proline analogues. In particular, compound 19-(S) showed promising in vitro/vivo pharmacological activities and properties as a selective cathepsin S inhibitor

  With respect to development of selective CatS inhibitors, we recently reported novel selective cathepsin S inhibitors based on a proline scaffold. Following up on this work, we herein report the synthesis of a series of proline analogues with vinyl sulfone group, which is a key functional group of LHVS. We evaluated these novel compounds for their in vitro CatS inhibitory activity to investigate a structure-activity

  组织蛋白酶 S (CatS) 是一种属于木瓜蛋白酶家族的半胱氨酸蛋白酶，由于 CatS 与抗原呈递过程密切相关，因此已被提议作为哮喘和自身免疫性疾病的有吸引力的治疗靶点。事实上，据报道，在类风湿性关节炎的胶原诱导关节炎 (CIA) 模型中，抑制 CatS 可减少慢性炎症性疼痛。因此，药物化学家对鉴定 CatS 抑制剂的兴趣日益浓厚。吗啉脲-亮氨酸高苯丙氨酸乙烯基砜 1（LHVS，图 1）之前已被确定为一种有效的 CatS 抑制剂，但对组织蛋白酶家族成员的选择性有限。许多选择性 CatS 抑制剂已被报道为潜在的治疗剂，包括氰肽-、吡咯并嘧啶-、氨基嘧啶-、基于氰基吡唑烷的抑制剂。尽管目前正在对一些 CatS 抑制剂进行临床试验评估，但仍然需要强效和选择性的 CatS 抑制剂。关于选择性 CatS 抑制剂的开发，我们最近报道了基于脯氨酸支架的新型选择性组织蛋白酶 S 抑制剂。继这项工作之后，我
