essentially tested to determine the influence of the polyamine chain on their cellular transport. To comment on affinity and on selective transport via the polyamine transport system (PTS), K(i) values for polyamine uptake were determined in L1210 cells, and the cytotoxicity and accumulation of the conjugates were determined in CHO and polyamine transport-deficient mutant CHO-MG cells, as well as in
制备了五组各种大小和复杂性的杂环衍生物,这些衍生物通过derivatives官能与腐胺,亚精胺或精胺偶联。基本上对它们进行了测试,以确定多胺链对其细胞运输的影响。为了评论通过多胺转运系统(PTS)的亲和力和选择性转运,测定了L1210细胞中多胺摄取的K(i)值,并确定了CHO和多胺转运不足的突变体CHO中缀合物的细胞毒性和累积-MG细胞,以及L1210和α-二氟甲基鸟氨酸(DFMO-)处理的L1210细胞。与精胺不同,腐胺和亚精胺被明确鉴定为选择性基序,使细胞可以通过PTS进入。但是,此性质显然受到取代基大小的限制:
