We report the parallel synthesis of gramicidin S derivatives featuring backbone N-amino substituents. Analogues were prepared by incorporation of N-amino dipeptide subunits on solid support. Nine backbone-aminated macrocycles were evaluated for growth inhibitory activity against ESKAPE pathogens and hemolytic activity against human red blood cells. Diamination of the Orn residues in the β-strand region
我们报道了具有主链N-氨基取代基的短杆菌肽 S 衍生物的平行合成。通过将N-氨基二肽亚基掺入固体支持物上来制备类似物。评估了九种骨架胺化大环化合物对 ESKAPE 病原体的生长抑制活性和对人红细胞的溶血活性。研究发现,短杆菌肽 S β 链区域的 Orn 残基的二价化可增强广谱抗菌活性,而不会相应增加溶血活性。

Successful biochemical studies of the natural products belactosin A and C as well as their more stable acylated derivatives have proved them to be powerful proteasome inhibitors and thereby potential candidates as pharmacologically relevant active compounds. In order to understand their structure–biological activity relations in detail and to find ways of improving their biological activity, four new modified belactosin congeners have been synthesized and tested. One of them (compound 6) turned out to be a more potent inhibitor against HeLa cells than the known proteasome inhibitor MG132.
对天然产物贝乳糖素 A 和 C 及其更稳定的酰化衍生物的成功生化研究证明它们是强大的蛋白酶体抑制剂,因此是作为药理学相关活性化合物的潜在候选者。为了详细了解它们的结构-生物活性关系并找到提高其生物活性的方法,合成并测试了四种新的修饰贝乳素同系物。其中一种(化合物 6)被证明是比已知的蛋白酶体抑制剂 MG132 更有效的 HeLa 细胞抑制剂。
