hydroxylated 4,3-triamine, and cyclohexylene-containing triamine] spacers. Two control compounds were also evaluated: N-(anthracen-9-ylmethyl)-butylamine and N-(anthracen-9-ylmethyl)-butanediamine. Biological activities in L1210 (murine leukemia), alpha-difluoromethylornithine (DFMO)-treated L1210, and Chinese hamster ovary (CHO) and its polyamine transport-deficient mutant (CHO-MG) cell lines were investigated
合成了在氮中心之间包含多个间隔单元的几种N(1)-取代的多胺,分别作为它们的HCl盐。N(1)-取代基包括苄基,萘-1-基甲基,蒽-9-基甲基和pyr-1-基甲基。聚胺间隔单元的范围从通用(4,4-三胺,4,3-三胺和二氨基辛烷)间隔到更奇特的[2-(乙氧基)乙氧基含二胺,羟基化4,3-三胺和含环己烯的三胺]垫片。还评估了两种对照化合物:N-(蒽-9-基甲基)-丁胺和N-(蒽-9-基甲基)-丁二胺。通过IC(50)细胞毒性测定研究了L1210(鼠白血病),α-二氟甲基鸟氨酸(DFMO)处理的L1210和中国仓鼠卵巢(CHO)及其多胺转运缺陷型突变(CHO-MG)细胞系的生物学活性。L1210细胞中亚精胺摄取的K(i)值也已确定。在研究的系列中,N(1)-苄基-4,4-三胺系统6在L1210,CHO和CHO-MG细胞系中具有显着较高的IC(50)值(较低的细胞毒性)。在具有6的L1210细胞
