4‐benzoquinone, a natural product from Pyrola media is described. The synthesis is based on a direct late C−H functionalization of the quinone scaffold. The formation of the natural product was confirmed by means of 2D‐NMR spectroscopy. Additional derivatives were synthesized and tested alongside the natural product as potential substrate and substrate‐based inhibitors of mitochondrial complex I (MCI). The
描述了一种来自Pyrola 培养基的天然产物 2-甲基-5-(3-甲基-2-丁烯基)-1,4-苯醌的短而有效的一步合成。该合成基于醌支架的直接后期 C-H 功能化。天然产物的形成通过 2D NMR 光谱证实。与天然产物一起合成并测试了其他衍生物作为线粒体复合物 I (MCI) 的潜在底物和底物抑制剂。构效关系研究导致发现了 3-methylbuteneoxide-1,4-anthraquinone ( 1i ),一种 IC 为50的抑制剂5 μM 对 MCI。在针对其他醌转化酶(包括琥珀酸脱氢酶和 Na(+)-易位 NADH:醌氧化还原酶)进行测试时,鉴定出的分子对 MCI 显示出高选择性。此外,鉴定出的抑制剂在基于细胞的增殖试验中也有活性。因此,1 i可以被认为是一种新型的 MCI 化学探针。
