14C-Labelled myosmine ([2′-14C]-3-(1-pyrrolin-2-yl)pyridine) was synthesized for autoradiography studies starting from [carboxyl-14C]-nicotinic acid by initial esterification of the latter in the presence of 1,1,1-triethoxyethane. Without any purification the ethyl nicotinate formed was directly reacted with N-vinyl-2-pyrrolidinone in the presence of sodium hydride, yielding 14C-labelled myosmine. The product was purified by silica gel column chromatography. The radiochemical yield was 15% and the specific activity 55.2 mCi/mmol. Copyright © 2003 John Wiley & Sons, Ltd.
14C 标记的肌球蛋白([2′-14C]-3-(1-吡咯啉-2-基)吡啶)是以[羧基-14C]-烟酸为起点,在 1,1,1-三乙氧基乙烷的存在下通过初步酯化合成的,用于自显影研究。在氢化钠存在下,形成的烟酸乙酯未经任何纯化便直接与 N-乙烯基-2-吡咯烷酮反应,生成 14C 标记的肌球蛋白。产物经硅胶柱色谱法纯化。放射化学收率为 15%,比活度为 55.2 mCi/mmol。Copyright © 2003 John Wiley & Sons, Ltd. All Rights Reserved.
