Three tritium-labelled isotopomers of histamine (HA) have been synthesized using combined chemical and enzymatic methods. In the first step the tritium-labelled isotopomers of histidine have been obtained by catalysed exchange with tritiated water. These intermediates have been converted into [1S-3H]-HA, [1R-3H]-HA and [2′,4′,1S,-3H3]-HA using the enzyme histidine decarboxylase (HDC, EC 4.1.1.22) from
已经使用化学和酶促方法组合合成了三种氚标记的组胺 (HA) 同位素异构体。在第一步中,通过与氚化水的催化交换获得了氚标记的组氨酸同位素异构体。这些中间体已使用组氨酸脱羧酶 (HDC, EC 4.1.1.22) 转化为 [1S-3H]-HA、[1R-3H]-HA 和 [2',4',1S,-3H3]-HA乳酸杆菌 30a。版权所有 © 2004 John Wiley & Sons, Ltd.
