compounds (DACs 3a-d) based on azabicyclo[5.3.0]decane (ABD) Smac mimetic scaffolds linked to Zn2+-chelating 2,2'-dipicolylamine (DPA) through their 4 position are reported and characterized. Their synthesis, their target affinity (cIAP1 BIR3, Zn2+) in cell-free assays, their pro-apoptotic effects, and their cytotoxicity in tumor cells with varying sensitivity to Smac mimetics are described. A limited
报告并表征了基于氮杂双环[5.3.0]癸烷(ABD)Smac模拟支架与Zn2 +螯合的2,2'-二甲基吡啶胺(DPA)连接的推定双作用化合物(DAC 3a-d),并对其进行了表征。描述了它们的合成,它们在无细胞测定中的靶亲和力(cIAP1 BIR3,Zn2 +),它们的促凋亡作用以及在对Smac模拟物敏感的肿瘤细胞中的细胞毒性。有时可以感觉到Zn2 +螯合对DPA取代的DAC 3a-d体外活性的有限影响,但并未导致强烈的细胞协同作用。特别是,将DPA与ABD支架连接的接头似乎会影响细胞的Zn2 +螯合,较长的亲脂性接头/ DAC 3c是最佳选择。
