结构复杂的大环化合物的合成程序非常具有挑战性。在此,我们提出了一种吡喃基化环缩酚肽 verucopeptin 的生物合成途径,通过基因操作和一步半合成来提供足够的供应并使 verucopeptin 多样化。该合成依赖于可互换的半缩酮吡喃和开环酮以及相邻烯烃的固有反应性。 Verucopeptin 类似物的生物学评估可提供有效的 AMP 激活蛋白激酶 (AMPK) 激动剂、抗菌剂和选择性 NFκB 调节剂。
A synthesis program for structurally complex macrocycles is very challenging. Herein, we propose a biosynthesis pathway of the pyranylated cyclodepsipeptide verucopeptin to make enough supply and to diversify verucopeptin by genetic manipulation and one-step semisynthesis. The synthesis relies on the intrinsic reactivity of the interchangeable hemiketal pyrane and opened keto along with adjacent alkene. Biological evaluation of verucopeptin-oriented analogs delivers a potent AMP-activated protein kinase (AMPK) agonist, antibacterial agent, and selective NFκB modulator.
