BACKGROUND/AIM: Due to its abilities of substance adsorption and intracellular transportation, hydroxyapatite is a potential carrier in drug delivery systems (DDS). This in vitro study investigated whether newly-developed, highly-dispersive calcined hydroxyapatite nanoparticles with an average grain diameter of 20 nm (nano-SHAP) were suitable as a DDS for the drugs zoledronic acid (ZA), cisplatin, and carboplatin.
MATERIAL AND METHODS
The effects of drug-bearing nano-SHAP on cell proliferation were assessed using three human oral squamous cell carcinoma cell lines (HSC-4, KOSC, and SAS) and one human breast cancer cell line (MCF-7).
RESULTS
Nano-SHAP alone did not affect proliferation of any cell line until a concentration of 1 μg/ml was reached. Although the effective concentration of ZA in ZA-bearing nano-SHAP differed, it inhibited cell proliferation better than ZA alone. Cisplatin and carboplatin-bearing nano-SHAP had the same effect as these drugs alone.
CONCLUSION
The nano-SHAP system is of potential use as a drug delivery system.
背景/目的：由于具有物质吸附和细胞内转运能力，羟基磷灰石是药物递送系统（DDS）中的一种潜在载体。本体外研究调查了新开发的平均粒径为20nm的高度分散煅烧羟基磷灰石纳米颗粒（纳米-SHAP）是否适合作为唑来膦酸（ZA）、顺铂和卡铂的药物递送系统。
材料与方法
使用三种人类口腔鳞状细胞癌细胞系（HSC-4、KOSC和SAS）和一种人类乳腺癌细胞系（MCF-7）评估载药纳米-SHAP对细胞增殖的影响。
结果
在达到1μg/ml浓度之前，单独的纳米-SHAP对任何细胞系的增殖均无影响。尽管载ZA纳米-SHAP中ZA的有效浓度有所不同，但它比单独的ZA更能抑制细胞增殖。载顺铂和卡铂的纳米-SHAP与单独使用这些药物具有相同的效果。
结论
纳米-SHAP系统作为药物递送系统具有潜在用途。
