analogue-mediated cytotoxicity and in overall cellular polyamine metabolism. Such analogues could also become important therapeutic agents by disrupting cellular polyamine metabolism. The structure-activity relationships defining the interaction of polyamine analogues with SSAT have not been fully elucidated, and, in particular, unsymmetrically alkylated polyamines have not been synthesized and evaluated as modulators
亚胺/亚精胺-N1-乙酰基转移酶(SSAT)是多胺分解代谢中的限速步骤,对细胞多胺的相互转化和调节至关重要。抑制剂引发的这种酶的诱导也似乎与肿瘤细胞对一类新型多胺类似物双(乙基)多胺的敏感性相关。因此,调节SSAT细胞水平的末端烷基化多胺对于理解该酶在类似物介导的细胞毒性和整个细胞多胺代谢中的作用可能具有重要价值。此类类似物还可通过破坏细胞多胺代谢而成为重要的治疗剂。尚未完全阐明定义多胺类似物与SSAT相互作用的结构活性关系,特别是,尚未合成不对称的烷基化多胺并将其评估为SSAT的调节剂。为此,我们现在通过合成途径报告N1-乙基-N11-炔丙基-4,8-二氮杂十二烷和N1-乙基-N11-((环丙基)甲基)-4,8-二氮杂十一烷的合成和初步生物学评估它代表了通往各种不对称取代的多胺类似物的有效途径。标题化合物充当分离的人SSAT的有效抑制剂,并在原位产生SSAT的差异超诱导,这似乎与
