摘要:

通过超分子相互作用构筑了以β-羟基氧化铁为结构基元的氨基酸-铁纳米组装体, 并探究了其在不同温度下的组装动力学, 明确了温度对其成核、 生长及组装过程的影响. 通过优化组装条件, 制备了长度为179.1 nm, 宽度为36.1 nm的梭形纳米组装体, 其中总铁(Fe)含量达到49.6%, 络合Fe含量占32.1%. 细胞实验结果表明, 所制备的氨基酸-铁纳米组装体可以被人膀胱移行细胞癌T24细胞高效内吞, 并显著抑制其增殖, 半数最大抑制浓度(IC50)为163.8 μg/mL, 展现出优异的肿瘤治疗潜力, 在纳米药物领域具有很广阔的研究 前景.

Abstract:

We employed supramolecular interactions to fabricate amino acid-iron nano-assemblies using β-iron hydroxide oxide as the building block. The dynamics of assembly at various temperatures was investigated, shedding light on how temperature influences the nucleation, growth, and assembly processes. By optimizing the assembly conditions, a shuttle-shaped nano-assembly with a length of 179.1 nm and a width of 36.1 nm was successfully prepared, featuring a total iron(Fe) content of 49.6%, with complex Fe accounting for 32.1%. Cell experiments demonstrated that this unique amino acid-iron nano-assembly could be efficiently uptaken by human bladder transitional cell carcinoma T24 cells and inhibited their proliferation, with a half maximal inhibitory concentration (IC50) of 163.8 μg/mL. These findings suggest that the nano-assembly possesses excellent tumor therapeutic potential and holds significant promise for research in the field of nanomedicine.
