proved to be a very potent inhibitor of that enzyme. Two synthetic routes to effect the coupling of the polyamine spermidine to the nucleoside adenosine were studied. The first route involved a proposed Wittig or Julia olefination reaction to form the critical 5'-6' carbon-carbon bond between the nucleoside and polyamine moieties. This route failed due to a facile beta-elimination of a portion of the side
研究了新型的多胺生物合成多底物加合物抑制剂的合成。获得了设计用于抑制亚精胺合酶的第一个目标化合物,并证明是该酶的非常有效的抑制剂。研究了影响多胺亚精胺与核苷腺苷偶联的两种合成途径。第一条途径涉及拟议的维蒂希或朱莉娅烯化反应,以在核苷和多胺部分之间形成关键的5'-6'碳-碳键。由于在任一偶联反应过程中从碳负离子中间体中容易除去一部分侧链,导致该路线失败。第二种方法涉及还原胺化方法,并证明是成功的。新的抑制剂,俗称腺苷亚精胺,
