has been identified as a novel therapeutic target for osteoarthritis. Here, we use DNA-encoded Library Technology (ELT) to identify novel ADAMTS-4 inhibitors from a DNA-encoded triazine library by affinity selection. Structure–activity relationship studies based on the selection information led to the identification of potent and highly selective inhibitors. For example, 4-(((4-(6,7-dimethoxy-3,4-
聚集蛋白聚糖降解金属蛋白酶ADAMTS-4已被鉴定为骨关节炎的新型治疗靶标。在这里,我们使用DNA编码文库技术(ELT)通过亲和力选择从DNA编码的三嗪文库中识别新型ADAMTS-4抑制剂。基于选择信息的结构-活性关系研究导致了强效和高选择性抑制剂的鉴定。例如,4-((((4-(6,7-二甲氧基-3,4-二氢异喹啉-2(1 H)-基)-6-((((4-甲基哌嗪-1-基)甲基)氨基)- -1,3,5-三嗪-2-基)氨基)甲基) - ñ乙基ñ - (米间-甲苯基)苯甲酰胺具有IC 50对ADAMTS-4具有10 nM的选择性,与ADAMT-5,MMP-13,TACE和ADAMTS-13相比,具有> 1000倍的选择性。这些抑制剂没有明显的锌配体功能。
