This article describes the development of nanostructured lipid carriers (NLC) as colloidal carriers for two antitumor compounds that possess a remarkable antineoplastic activity. But their limited stability and low solubility in water could give a very low parenteral bioavailability. Results revealed an enhancement of the cytotoxicity effect of drug-loaded NLC on human prostate cancer (PC-3) and human hepatocellular carcinoma (HuH-6, HuH-7) cell lines with respect to that of both free drugs. Results of characterization studies strongly support the potential application of these drugs-loaded NLC as prolonged delivery systems for lipophilic drugs by several administration routes, in particular for intravenous administration.
本文描述了纳米结构脂质载体(NLC)作为两种具有显著抗肿瘤活性的抗肿瘤化合物的胶体载体的发展情况。但它们有限的稳定性和在水中的低溶解度可能导致肠胃外生物利用度非常低。结果显示,相对于游离药物,载药NLC对人前列腺癌(PC-3)和人肝癌(HuH-6、HuH-7)细胞系的细胞毒性作用有所增强。表征研究结果有力地支持了这些载药NLC作为亲脂性药物通过多种给药途径(特别是静脉给药)的长效递送系统的潜在应用。
