Abstract

The synthesis and biological analysis of a number of novel congeners of the aminocyclopentitol pactamycin is described. Specific attention was paid to the preparation of derivatives at crucial synthetic branch points of the parent structure, and biological assays revealed a number of insights into the source of pactamycin's biological activity. Additionally, the encapsulation of pactamycin and select derivatives into the PRINT© nanoparticle technology was investigated as a proof-of-concept, and evidence of bioactivity modulation through nanoparticle delivery is demonstrated. This work has provided heretofore unrealized access to a large number of novel compounds for further evaluation.

摘要

描述了氨基环戊醇派克霉素的一些新型同系物的合成及生物学分析。特别关注了母体结构关键合成分支点处衍生物的制备,生物学测定揭示了关于派克霉素生物活性来源的一些见解。此外,作为概念验证,研究了将派克霉素和选定的衍生物封装到PRINT©纳米颗粒技术中,并证明了通过纳米颗粒递送调节生物活性的证据。这项工作为进一步评估大量新型化合物提供了前所未有的途径。
