straightforward strategy to multimerize an apoptogenic peptide that mimics the natural tumor necrosis factor‐related apoptosis‐inducing ligand (TRAIL) by using adamantane‐based dendrons as multivalent scaffolds. The selective binding affinity of the ligands to TRAIL receptor 2 (TR2) was studied by surface plasmon resonance, thus demonstrating that the trimeric and hexameric forms of the peptide exert an increased
我们已经开发出一种直接的策略,可以使用基于金刚烷的树突作为多价支架,使模拟自然肿瘤坏死因子相关的凋亡诱导配体(TRAIL)的凋亡肽进行多聚化。通过表面等离振子共振研究了配体对TRAIL受体2(TR2)的选择性结合亲和力,因此证明该肽的三聚体和六聚体形式分别具有相对于1500倍和20 000倍的增加的亲和力。单体。此外,只有三聚体和六聚体配体能够诱导TR2表达细胞(BJAB)的细胞死亡,因此证实了多肽的多价形式对于在体外触发实质性的依赖于TR2的细胞凋亡反应是必需的。
