Abstract

We have isolated a compound responsible for the cytokinin activity of soluble RNA from Escherichia coli. The structure, indicated as 6-(3-methyl-2-butenylamino)-2-methylthio-9-beta-D-ribofuranosylpurine, C(16)H(23)N(5)0(4)S, on the basis of low-and high-reso!ution mass spectrometry, was established by unequivocal synthesis. The mass spectra, chromatographic behavior, and ultraviolet spectra of the compounds from natural and synthetic sources were identical.

摘要

我们从大肠杆菌中分离出一种负责可溶性RNA细胞分裂素活性的化合物。基于低分辨率和高分辨率质谱分析，其结构被确定为6-(3-甲基-2-丁烯基氨基)-2-甲硫基-9-β-D-呋喃核糖基嘌呤，化学式为C(16)H(23)N(5)0(4)S。通过明确的合成方法确定了该结构。天然来源和合成来源的化合物的质谱、色谱行为和紫外光谱均相同。
