As a new scaffold for peptidomimetic synthesis, a highly constrained bifunctional diketopiperazine, 4, has been prepared by smooth N-alkylation with tert-butyl bromoacetate. As a first application, we describe herein the synthesis of new peptidomimetics of the Arg-Gly-Asp (RGD) sequence. The product 30, which shows a selective platelet-aggregation inhibiting activity, can be used as a lead for the
作为肽模拟物合成的新支架,高度受限的双功能二酮哌嗪 4 已通过与叔丁基溴乙酸酯平滑 N-烷基化制备。作为第一个应用,我们在此描述了 Arg-Gly-Asp (RGD) 序列的新肽模拟物的合成。表现出选择性血小板聚集抑制活性的产品30可用作制备更有效产品的先导物。
