furan amino acid as a core structure. They show a moderate cytotoxic activity and induce upregulation of cell cycle regulating proteins (p53 and p21) and lead to cell cycle arrest in G0/G1-phase. Hybrid molecules combining structural motifs of the proximicins and of netropsin (4), a structurally related natural product, seem to have similar effects. Herein we describe the synthesis of a netropsin–proximicin-hybrid
所述proximicins A-C(1 - 3)是新的天然存在的γ-肽具有迄今未知的2,4-二取代的呋喃氨基酸作为核心的结构。它们显示出中等的细胞毒活性,并诱导细胞周期调节蛋白(p53和p21)的上调,并导致细胞周期停滞在G0 / G1期。结合proximicin和netropsin(4)(一种与结构相关的天然产物)的结构基序的杂合分子似乎具有相似的作用。在这里,我们描述了netropsin-proximicin杂交文库的合成及其对细胞毒性和小沟结合活性的评估。
