efficiency in vivo presents a great challenge. Thus, we proposed to design an anticancer multitarget metal pro-drug derived from thiosemicarbazone based on the His146 residue in the IB subdomain of palmitic acid (PA)-modified human serum albumin (HSA-PA). The structure–activity relationship of six Cu(II) compounds with 6-methyl-2-formylpyridine-4N-substituted thiosemicarbazones were investigated, and then
设计具有改善的体内递送和治疗效率的多靶点抗癌药物提出了巨大的挑战。因此,我们建议基于棕榈酸(PA)修饰的人血清白蛋白(HSA-PA)IB亚域中的His146残基,设计一种衍生自硫半脲的抗癌多靶标金属前药。研究了六种Cu(II)化合物与6-甲基-2-甲酰基吡啶-4 N-取代的硫代半氨基甲酮的结构-活性关系,然后证实了4b在癌细胞DNA和蛋白质中的多靶标能力。HSA–PA– 4b复合物(HSA–PA– 4b)的结构揭示了4b结合到修饰的HSA的IB子结构域,并且His146取代4b中的硝酸盐配体,与Cu 2+配位,而PA通过与Lys199和His242形成氢键的羧基与IIA子结构域复合。体内数据显示4b和HSA–PA– 4b复合物抑制肺肿瘤的生长,并且PA修饰的HSA复合物的靶向能力和治疗功效强于单独的4b。
