A model compound of the novel organic cofactor CTQ (cysteine tryptophylquinone) of quinohemoprotein amine dehydrogenase (QH-AmDH) has been synthesized for the first time by the Michael addition of phenylmethanethiol to the 3-methyl-6,7-indolequinone derivative as a key step. The model compound replicates the characteristic absorption spectrum of native CTQ as well as its redox potential in the γ subunit
通过将苯基甲硫醇作为关键化合物与 3-甲基-6,7-吲哚醌衍生物进行迈克尔加成,首次合成了喹血蛋白胺脱氢酶 (QH-AmDH) 的新型有机辅因子 CTQ(半胱氨酸色氨酸醌)的模型化合物步。模型化合物复制了天然 CTQ 的特征吸收光谱及其在 QH-AmDH γ 亚基中的氧化还原电位。模型化合物的详细结构和光谱表征为 CTQ 硫醚基团的取代作用提供了重要的见解。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
