thirty-six Sansalvamide A derivatives, and their biological activity against colon cancer HT-29 cell line, a microsatellite stable (MSS) colon cancer cell-line. The thirty-six compounds can be divided into three subsets, where the first subset of compounds contains L-amino acids, the second subset contains D-amino acids, and the third subset contains both D- and L-amino acids. Five compounds exhibited
我们报告了36种Sansalvamide A衍生物的合成及其对结肠癌HT-29细胞系(一种微卫星稳定(MSS)结肠癌细胞系)的生物活性。这三十六种化合物可分为三个子集,其中化合物的第一子集包含L-氨基酸,第二个子集包含D-氨基酸,而第三子集包含D-和L-氨基酸。五种化合物表现出出色的抑制活性(抑制率> 75%)。化合物的结构活性关系(SAR)确定了位置2或3上的单个D-氨基酸比Sansalvamide A肽的细胞毒性提高了10倍。这项工作强调了残基2和3的重要性以及D-氨基酸在该类化合物的非常规SAR中的作用。
