metabolites (1 and 2) were isolated from ICA-treated rice, and their structures were determined by spectroscopic analysis including the single-crystal X-ray diffraction technique and synthesis. The ribotide of ICA (3), whose existence was predicted, was also synthesized and detected from the treated rice by LC–MS/MS. These results indicated that rice might interconvert ICA, 1, and 3 to regulate the biological
咪唑-4-羧
酰胺(ICA)在植物中的代谢是未知的。从ICA处理的大米中分离出两种代谢物(1和2),并通过光谱分析(包括单晶X射线衍射技术和合成方法)确定了它们的结构。还可以通过LC-MS / MS从处理过的
水稻中合成并检测到ICA的
核糖核苷酸(3),并对其进行了检测。这些结果表明大米可能会相互转化ICA,1和3,从而调节其
