摘要: 将介孔58S生物活性玻璃(m58S)作为抗癌药物载体评价了其对表阿霉素的装载量和释放性能. 实验结果表明, m58S对亲水性药物表阿霉素的药物装载量为40%, 是普通溶胶-凝胶58S生物活性玻璃的3倍多, 并且具有更长效的缓释特性. 研究还发现释放介质的pH值对表阿霉素的释放速率有很大影响, pH值越低, 表阿霉素分子从载体材料中释放出的速率越快. 因此, 介孔生物活性玻璃是一种高效的药物缓释载体, 且药物释放速率受释放介质pH值影响, 有望成为药物控释型骨修复材料.

Abstract: Mesoporousbioactive glasses m58S were loaded with an anticancer drug-Epirubicin hydrochloride(EPI) and the release of the drug from the glasses was evaluated. The drugloading capacity of m58S for EPI was 40%, which was three times higher thanthat of conventional Sol-Gel bioactive glasses 58S. In phosphate buffered saline (PBS), the m58S-EPI system showed asustained release behavior. Furthermore, the release rates from the EPI-m58Ssystem increased with the decrease of pH values of the release medium. Theresults suggest that m58S is an effective anticancer drug carrier and itspH-related release behavior suggests that it has potential for design ofcontrolled drug delivery bone grafting materials.

Key words: bioactive glasses, mesoporous materials, drug delivery system
