the structure-activity study, that required the synthesis of 48 analogues. We found that while the carboxylic acid, the imidazole and the tertiary amine were critical for activity, the methyl ester was successfully optimized to an amide or a 1,2,4-oxadiazole. Along with improving their activity, compounds were optimized for solubility, lipophilicity and stability in plasma and microsomes. The docking
胰岛素降解酶(IDE)是一种锌金属蛋白酶,可降解小的淀粉样肽,例如β-淀粉样蛋白和胰岛素。到目前为止,IDE特异性药理抑制剂的缺乏影响了对其在阿尔茨海默氏病生理病理学中的作用,淀粉样蛋白-α清除及其作为潜在治疗靶点的验证的了解。击中1以前是通过高通量筛选发现的。在这里,我们描述了结构活性研究,该研究需要合成48个类似物。我们发现,尽管羧酸,咪唑和叔胺对于活性至关重要,但甲酯已成功优化为酰胺或1,2,4-恶二唑。除了提高活性外,还优化了化合物在血浆和微粒体中的溶解度,亲脂性和稳定性。一些化合物在IDE的外位或催化位点上的对接或共结晶为IDE抑制提供了结构基础。在体内测定了最佳化合物44和46的药代动力学特性。结果是44(BDM43079)其甲酯前体48(BDM43124)是探索IDE作用的有用化学探针。
