In this report, we show that a very common modification (especially in tRNA), dihydrouridine, was efficiently produced by photoreduction of the canonical pyrimidine ribonucleoside, uridine in formamide. Formamide not only acts as a solvent in this reaction, but also as the reductant. The other three components of the canonical alphabet (C, A, G) remained intact under the same conditions, suggesting that dihydrouridine might have coexisted with all four canonical RNA nucleosides (C, U, A, G) at the dawn of life.

甲酰胺中尿苷光还原合成二氢尿苷的益生元
在本报告中,我们展示了一种非常常见的修饰(尤其是在 tRNA 中)二氢尿苷,是通过经典嘧啶核糖核苷(甲酰胺中的尿苷)的光还原有效产生的。甲酰胺在此反应中不仅充当溶剂,而且还充当还原剂。规范字母表的其他三个组成部分(C、A、G)在相同条件下保持完整,这表明二氢尿苷可能在生命诞生之初就与所有四种规范 RNA 核苷(C、U、A、G)共存。
