Abstract

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).
