An aspirin-ligated cisplatin derivative, biasplatin, was prepared from acetylsalicylic anhydride and oxoplatin in DMF. Biasplatin was synthesized from oxoplatin and aspirin anhydride as starting materials by a substitution reaction of hydroxo leaving groups in its axial position. The obtained biasplatin was fully characterized by FTIR, 1HNMR, 13CNMR, and ESI mass spectroscopy. Biasplatin entrapped into MIL-101(Fe) by suspended in DMF and stirring for 72 h at ambient temperature, known as biasplatin@MIL-101(Fe). The slow release of biasplatin and biasplatin@MIL-101(Fe) was conducted in PBS solution pH 7.20, 37 °C as media and measured by UV–Vis spectrophotometer. The release of biasplatin without loaded into MIL-101(Fe) is persistent for 3%, and biasplatin@MIL-101(Fe) is 0.05% over 72 h. A significant slow release of biasplatin@MIL-101(Fe) only 1% compared with time release of biasplatin without loaded into MIL-101(Fe).
一种结合了阿司匹林的顺铂衍生物——偏铂,是通过在DMF中将乙酰水杨酸酐和氧铂反应制备的。偏铂是通过将氧铂和水杨酸酐作为起始材料,通过在其轴向位置上的羟基离去基团的取代反应合成的。获得的偏铂通过FTIR、1HNMR、13CNMR和ESI质谱进行了充分表征。偏铂悬浮在DMF中并搅拌72小时于室温下包封进MIL-101(Fe),即称为偏铂@MIL-101(Fe)。在pH 7.20的PBS溶液中、37 °C条件下进行偏铂和偏铂@MIL-101(Fe)的缓慢释放实验,并通过紫外-可见光谱仪进行测量。不包封进MIL-101(Fe)的偏铂释放量持续为3%,而偏铂@MIL-101(Fe)则是0.05%,均为72小时内的释放。与不包封进MIL-101(Fe)的偏铂相比,偏铂@MIL-101(Fe)的释放量非常缓慢,仅1%。
