Two novel chlorinated pyrones, halomadurones A and B, and two novel brominated analogues, halomadurones C and D, were isolated from a marine Actinomadura sp. cultivated from the ascidian Ecteinascidia turbinata. Additionally, a non-halogenated analogue, 2-methyl-6-((E)-3-methyl-1,3-hexadiene)-γ-pyrone, was synthesized to understand the role of the halogens for activity. Halomadurones C and D demonstrated potent nuclear factor E2-related factor antioxidant response element (Nrf2-ARE) activation, which is an important therapeutic approach for treatment of neurodegenerative diseases.
从一种海洋放线菌(Actinomadura sp.)中分离出了两种新型氯化吡喃酮--卤马杜隆A和B,以及两种新型溴化类似物--卤马杜隆C和D。此外,还合成了一种非卤代类似物 2-甲基-6-((E)-3-甲基-1,3-己二烯)-γ-吡喃酮,以了解卤素在活性中的作用。卤马杜龙 C 和 D 能有效激活核因子 E2 相关因子抗氧化反应元件(Nrf2-ARE),这是治疗神经退行性疾病的一种重要方法。
