A novel chemical platform based on branched piperazine-2,5-dione derivatives (2,5-diketopiperazines) for creating orally available biologically active peptidomimetics has been developed. The platform includes a diketopiperazine scaffold with "built-in" functionally active peptide fragments covalently attached via linkers. The concept was applied to two hemostimulatory drugs, the dipeptide thymogen
开发了一种基于支链哌嗪-2,5-二酮衍生物(2,5-二酮哌嗪)的新型化学平台,用于创建口服生物活性肽模拟物。该平台包括二酮哌嗪支架,其具有通过接头共价连接的“内置”功能活性肽片段。这一概念应用于两种止血药物,即二肽胸腺原 (GluTrp) 和三肽 Stemokin (IleGluTrp)。描述了一系列各自衍生物的制备。在五种合成的类似物中,三种在完整小鼠体内和离体辐射骨髓细胞中表现出高血液刺激活性。讨论了该概念进一步发展的前景。
