  cyclobutanone structural motif was investigated using a collection of eight monooxygenases of different bacterial origin. This platform of enzymes is able to perform stereoselective biotransformations on an array of structurally diverse substrates. With several ketone precursors, biooxidations yielded enantiocomplementary butyrolactones as key intermediates for the synthesis of natural products and bioactive compounds

  lignano-9,9′-lactones (α,β-dibenzyl-γ-butyrolactone lignans), which showed the higher cytotoxicity than arctigenin, were synthesized. The well-known cytotoxic arctigenin showed activity against HL-60 cells (EC50 = 12 μM), however, it was inactive against HeLa cells (EC50 > 100 μM). The synthesized (3,4-dichloro, 2′-butoxy)-derivative 55 and (3,4-dichloro, 4′-butyl)-derivative 66 bearing the lignano-9

  合成了新的木质素-9,9'-内酯（α，β-二苄基-γ-丁内酯木脂素），其细胞毒性高于arctigenin。众所周知的细胞毒性artigenin对HL-60细胞具有活性（EC 50  = 12μM），但是对HeLa细胞没有活性（EC 50  > 100μM）。具有木质素-9,9'-内酯结构的合成的（3,4-二氯，2'-丁氧基）衍生物55和（3,4-二氯，4'-丁基）衍生物66的EC 50值为分别针对HL-60细胞10μM和9.4μM。对于HeLa细胞，衍生物66的EC 50值为27μM。通过将活性与相应的9,9'-环氧结构（四氢呋喃化合物）进行比较，表明了55和66的内酯结构对于更高活性的重要性。木质素9,9'-内酯芳香环上的取代基影响细胞毒性水平，差异超过10倍。

  a non-competitive antagonist. Molecular docking studies in which 6c was docked into the X-ray crystal structure of the GluA2 tetramer suggest that (−)-arctigenin and its analogues bind in the transmembrane domain in a similar manner to the known AMPA receptor non-competitive antagonists GYKI53655 and the antiepileptic drug perampanel. The arctigenin derivatives described herein may serve as novel leads

  (−)-Arctigenin 和一系列新类似物已被合成，然后使用 Ca 2+流入测定测试其作为 HEK293 细胞中表达的人同聚 GluA1 和 GluK2 受体的 AMPA 和红藻氨酸受体拮抗剂的潜力。一般来说，这些化合物对两种受体都显示出拮抗剂活性，并且对 AMPAR 的活性明显更高。 Schild 分析表明螺环类似物6c充当非竞争性拮抗剂。分子对接研究表明， 6c对接至 GluA2 四聚体的 X 射线晶体结构中，表明 (−)-牛蒡苷元及其类似物在跨膜结构域中的结合方式与已知的 AMPA 受体非竞争性拮抗剂 GYKI53655 和抗癫痫药吡仑帕奈。本文描述的牛蒡甙元衍生物可以作为开发治疗癫痫的药物的新先导物。
