Herein is described a new modular platform for the construction of cancer‐cell‐targeting drug conjugates. Tripodal boronate complexes featuring reversible covalent bonds were designed to accommodate a cytotoxic drug (bortezomib), poly(ethylene glycol) (Peg) chains, and folate targeting units. The B‐complex core was assembled in one step, proved stable under biocompatible conditions, namely, in human
本文介绍了一种用于构建靶向癌细胞的药物偶联物的新型模块化平台。具有可逆共价键的三脚架硼酸酯络合物设计用于容纳细胞毒性药物(硼替佐米),聚乙二醇(PEG)链和叶酸靶向单元。B-复合体核心一步组装完成,在生物相容性条件下(即在人血浆中(半衰期长达60小时))在生物相容性条件下证明是稳定的,并在存在谷胱甘肽(GSH)的情况下进行了拆解。共聚焦荧光显微镜证实了刺激响应的细胞内货物递送,并在质谱和DFT计算的基础上提出了GSH诱导的B-复合物水解的机制。纳摩尔范围内的50个值。
