rocaglate (flavagline) naturalproduct, aglaroxin C displays intriguing biological activity by inhibiting hepatitis C viral entry. To further elucidate structure-activity relationships and diversify the pyrimidinone scaffold, we report a concise synthesis of aglaroxin C utilizing a highly regioselective pyrimidinone condensation. We have prepared more than 40 aglaroxin C analogues utilizing various amidine
作为一种独特的 rocaglate (flavagline) 天然产物,aglaroxin C 通过抑制丙型肝炎病毒进入显示出有趣的生物活性。为了进一步阐明构效关系并使嘧啶酮支架多样化,我们报告了利用高度区域选择性嘧啶酮缩合的 aglaroxin C 的简明合成。我们已经利用各种脒缩合伙伴制备了 40 多种 aglaroxin C 类似物。通过对类似物的生物学评估,我们发现了两种先导化合物 CMLD012043 和 CMLD012044,它们显示出对丙型肝炎病毒进入抑制与翻译抑制的优先偏向。总体而言,该研究证明了化学合成能够产生具有靶向抑制偏向性和改善的治疗指数的天然产物变体。

structure. The totalsynthesis of a reported natural product, 3′-hydroxymethylrocaglate (5), was achieved using [3 + 2] cycloaddition between 3-hydroxyflavone and methyl cinnamate. We also describe the synthesis of rocaglamide heterocycle derivatives and evaluate their Wnt signal inhibitoryactivities. Compounds 4, 5, 22a, 22b, 22c and 23c showed potent Wnt signal inhibitoryactivity.
乐卡格酰胺是具有环戊[ b ]苯并呋喃核心结构的生物活性天然化合物。使用3-羟基黄酮和肉桂酸甲酯之间的[3 + 2]环加成反应,可以完成报告的天然产物3'-羟甲基rocaglate(5)的总合成。我们还描述了rocaglamide杂环衍生物的合成,并评估其Wnt信号抑制活性。化合物4,5,图22A,22B,22C和23C显示了强的Wnt信号的抑制活性。

The synthesis of a library of halogenated rocaglate derivatives belonging to the flavagline class of natural products, of which silvestrol is the most prominent example, is reported. Their antiviral activity and cytotoxicity profile against a wide range of pathogenic viruses, including hepatitis E, Chikungunya, Rift Valley Fever virus and SARS-CoV-2, were determined. The incorporation of halogen substituents
