Abstract
A novel porous Cd(ii) metal–organic framework (MOF) with the chemical composition of [H3O][Cd(bci)]}
n
·2n(H2O) (1, H3bci = bis(2-carboxyethyl)isocyanurate) was prepared via hydrothermal responses of H3bci and Cd(NO3)2·4H2O. Luminescent property investigations indicated that compound 1 had high sensitivity toward Fe3+, and the detection limit of Fe3+ was as low as 2.15 × 10−4 M. The application values of Fe3+ on Hepatitis B were assessed, and its associated mechanism was identified simultaneously. First, the cytotoxic mediator (TNF-α) substance released into plasma was measured through the ELISA. In addition, real-time RT-PCR was employed to determine the Hepatitis B viral replication gene relative expression levels. Finally, the novel compound’s toxicity against human normal liver cells was tested by using the CCK-8 assay.
摘要
通过H3bci和Cd(NO3)2·4H2O的水热反应,制备了一种新型多孔Cd(ii)金属-有机框架(MOF),化学组成为[H3O][Cd(bci)]}n·2n(H2O) (1,H3bci = 双(2-羧基乙基)异氰尿酸)。发光性质研究表明,化合物1对Fe3+具有高灵敏度,Fe3+的检测限低至2.15×10−4 M。评估了Fe3+在乙型肝炎上的应用价值,并同时确定了其相关机制。首先,通过ELISA测量了释放到血浆中的细胞毒性介质(TNF-α)物质。此外,采用实时RT-PCR确定了乙型肝炎病毒复制基因相对表达水平。最后,使用CCK-8试验测试了新化合物对人正常肝细胞的毒性。
