Cruciferous vegetables (CVs) are globally consumed with some health benefits believed to arise from indole-3-carbinol (I3C), a labile phytochemical liberated from indole glucosinolates, but few reports describe the effect of cooking on I3C reactions. Here, we present heat-promoted direct conversions of I3C in broccoli florets into indole derivatives, which are unique in the -indolylmethylation and -hydroxymethylation
全球范围内食用的十字花科蔬菜 (CV) 对健康有益,据信这些益处来自吲哚 3-甲醇 (I3C),这是一种从吲哚芥子油苷中释放出来的不稳定植物化学物质,但很少有报告描述烹饪对 I3C 反应的影响。在这里,我们提出了西兰花小花中I3C在热促进下直接转化为吲哚衍生物,其独特之处在于通过I3C脱水和I3C二聚而原位形成的3-亚甲基吲哚和甲醛对吲哚核进行β-吲哚基甲基化和β-羟甲基化,从而生成吲哚衍生物。分别为 3,3'-二吲哚基甲烷 (DIM)。每克蒸西兰花小花中发现此类取代吲哚的含量为 0.4–4.6 μg,其中一种新型化合物 -(吲哚-3-基甲基)-3,3'-二吲哚基甲烷 (DIM-1) 经生物评估可抑制A375 细胞的 IC 值为 1.87 μM。总的来说,该研究揭示了加热对CV中I3C转化的促进作用,并将DIM-1鉴定为抗癌候选药物,从而更新了对I3C及其生物活性衍生物的认识。
