N(1)-anthracen-9-ylmethyl, N(1)-2-(anthracen-9-yl)ethyl, N(1)-3-(anthracen-9-yl)propyl, and pyren-1-ylmethyl. The polyamine architecture was also altered and ranged from diamine to triamine and tetraamine systems. Biological activities in L1210 (murine leukemia), Chinese hamster ovary (CHO), and CHO's polyamine transport-deficient mutant (CHO-MG) cell lines were investigated via IC(50) cytotoxicity determinations
合成了几种含有各种芳环系统的N(1)-芳基烷基多胺作为它们各自的HCl盐。评估的N(1)取代基大小从N(1)-苄基,N(1)-萘-1-基甲基,N(1)-2-(萘-1-基)乙基,N(1) -3-(萘-1-基)丙基,N(1)-蒽-9-基甲基,N(1)-2-(蒽-9-基)乙基,N(1)-3-(蒽-9 -基)丙基和pyr-1-基甲基。多胺的结构也被改变,范围从二胺到三胺和四胺体系。通过IC(50)细胞毒性测定研究了L1210(鼠白血病),中国仓鼠卵巢(CHO)和CHO的多胺转运缺陷型突变体(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。N(1)-芳基烷基取代基的大小以及所用的多胺序列直接影响到观察到的细胞毒性谱。如CHO / CHO-MG细胞毒性筛选所示,比乙烯长的N(1)-系链显示出对多胺转运蛋白(PAT)的选择性显着丧失。总之,对于N(1)取代基的大小有明确
