Dihydromotuporamine C (4) and its 4,4-triamine analogue (5) were synthesized in good yield using ring-closing metathesis (RCM) methods. Comparison of their biological activities (Ki determinations in L1210 cells and IC50 determinations in L1210, CHO, and CHO-MG cells) revealed that the motuporamine derivatives do not use the polyamine transporter (PAT) for cellular entry. Bioevaluation of a N1-(an
使用闭环复分解(RCM)方法以高收率合成了二氢motuporamine C(4)及其4,4-三胺类似物(5)。比较它们的生物学活性(L1210细胞中的Ki测定和L1210,CHO和CHO-MG细胞中的IC50测定)表明,motuporamine衍生物不使用多胺转运蛋白(PAT)进入细胞。N1-(蒽-9-基甲基)-N1-(乙基)高嘧啶对照的生物评价(7)显示,N1叔胺中心的存在显着降低了多胺缀合物的PAT亲和力,并废除了其PAT-定位选择性。
