Based on the structure activity relationship of 2-(4-phenoxybenzoyl)-5-hydroxyindole (1), a novel structural class of Ca2+/calmodulin-dependent protein kinase II (CaMKII) inhibitors were synthesized. We show in this study that the acidic proton at the N(1)-position of the indole moiety is not essential for CaMKII inhibitory activity. Among the synthesized compounds, we found the benzofuran and benzothiazole derivative as promising scaffolds for the developement of potent CaMKII inhibitors. In particular, compounds 8 and 14 inhibited CaMKII with IC50 values of 24 nM and 32 nM, respectively.
基于 2-(4-苯氧基苯甲酰基)-5-羟基吲哚 (1) 的结构活性关系,合成了一类新型结构的 Ca2+/钙调蛋白依赖性蛋白激酶 II (CaMKII) 抑制剂。我们在这项研究中表明,吲哚部分 N(1) 位的酸质子对于 CaMKII 抑制活性不是必需的。在合成的化合物中,我们发现苯并呋喃和苯并噻唑衍生物作为开发有效 CaMKII 抑制剂的有前途的支架。特别是,化合物 8 和 14 抑制 CaMKII,IC50 值为 24 nM 和 32 nM,分别。
