The total synthesis of PF1171B, D, and E, and avellanins A, B, and C, which are cyclic pentapeptides containing non-proteinogenic amino acid residues, was achieved by solid-phase peptide elongation and solution-phase macrolactamization. PF1171B and D and avellanins A and C were found to inhibit apolipoprotein B production in Hep G2 cells without exhibiting cytotoxicity. PF1171B had the most potent
通过固相肽延伸和溶液相大内酰胺化实现了PF1171B、D和E以及avellanin A、B和C(含有非蛋白氨基酸残基的环状五肽)的全合成。发现 PF1171B 和 D 以及 avellanins A 和 C 可以抑制 Hep G2 细胞中载脂蛋白 B 的产生,但不表现出细胞毒性。 PF1171B 对载脂蛋白 B 的产生具有最强的抑制活性。 PF1171B 对映体和线性类似物的合成和生物活性评估表明了其基本结构特征。
