BACE led to the design and synthesis of a series of constrained P(1)' analogues. A cyclopentane ring was incorporated in 1 spanning the P(1)' Ala methyl group and the adjacent methylene carbon atom of the chain. Progressive truncation at the P(2)'-P(4)' sites led to a potent truncated analogue 5 with good selectivity over Cathepsin D. Using the same backbone replacement concept, a series of cyclopentane
基于BACE的Tang-Ghosh七肽抑制剂1(OM99-2)的X射线晶体结构的分子建模,导致设计和合成了一系列受约束的P(1)'类似物。1个环戊烷环结合在P(1)'Ala甲基和该链的相邻亚甲基碳原子上。在P(2)'-P(4)'位点的逐步截短导致有效的截短的类似物5,对组织蛋白酶D具有良好的选择性。使用相同的骨架替换概念,一系列环戊烷,环戊酮,四氢呋喃,吡咯烷和吡咯烷酮合成的类似物在P和P'位点有相当大的变化。环戊酮和2-吡咯烷酮类似物45和57显示出较低的nM BACE抑制作用。
