A tough nut to crack: In contrast to azadipeptide nitriles containing a P2 leucine residue, the synthesis of the corresponding homocycloleucine‐based inhibitors was more difficult; possibly due to the gem‐dialkyl effect. A synthetic route to the first homocycloleucine‐derived azadipeptide nitriles as selective and highly potent cathepsin K inhibitors is presented (see scheme).
一个难以克服的难题:与含有P2亮氨酸残基的氮杂肽腈相比,相应的基于同环亮氨酸的抑制剂的合成更加困难。可能是由于宝石二烷基效应。提出了合成第一个由同环亮氨酸衍生的氮杂二肽腈作为选择性和高效组织蛋白酶K抑制剂的合成途径(参见方案)。
