1. Here we report the diastereoselective total synthesis of 1, utilizing 9-fluorenylmethyloxycarbonyl (Fmoc)-based solid-phase peptide synthesis. During this study, we found that the structural correction of 1 was required, due to the mislabeling of the commercially obtained 3-amino-2-methylpropionic acid, and the true structure of 1 was corroborated by the chemical synthesis and chromatographic comparison
Surugamide F是从海洋衍生链霉菌属物种中分离的线性十肽(1)与环状八肽surugamides AE(2-6)。线性肽1是由在相邻的开放阅读框中编码的两个非核糖体肽合成酶(NRPS)产生的,它们进一步侧翼于负责环状肽2-6的生物合成的另一对NRPS基因。虽然环状肽2-6被鉴定为组织蛋白酶B抑制剂,但新代谢产物1的生物学活性仍不清楚。为了详细阐明其独特的生物合成途径和生物活性,我们计划开发一条通向1的有效合成途径。在这里,我们报告利用9-芴基甲氧基羰基(Fmoc)-基于固相肽合成的非对映选择性全合成。在这项研究中
