Curcumin is a potent anticancer agent and has great potential efficacy against different types of cancers. A major disadvantage of curcumin, however, is its poor solubility and bioavailability.
The aim of the present work is to synthesize chitosan and curcumin-loaded chitosan nanoparticles and their characterization through various physicochemical methods and cellular uptake in cervical cancer cell line SiHa.
Chitosan nanoparticles were synthesized through the method of ionic gelation of chitosan with sodium Tripolyphosphate (TPP). In addition, the internal structure of chitosan nanoparticles and curcumin loaded chitosan nanoparticles were characterized by DLS, UV-Visible spectrophotometer, DSC, LCMS and LDH assay.
The studies presented demonstrate that curcumin-loaded chitosan nanoparticles showed increased uptake in the SiHa cells as compared to free curcumin and chitosan nanoparticles did not show any significant uptake in SiHa cell line. The curcumin-loaded chitosan nanoparticles released more lactate and lower ATP as compared to native curcumin in cervical cancer lines such as SiHa, CaSki and HeLa.
Thus, chitosan based curcumin nanoparticles could be used as a potent vector / delivery agent for drug targeting in the treatment of cervical cancer.
姜黄素是一种有效的抗癌剂,对不同类型的癌症具有巨大的潜在疗效。然而,姜黄素的一个主要缺点是其溶解性和生物利用度差。
本研究旨在合成壳聚糖和负载姜黄素的壳聚糖纳米颗粒,并通过各种物理化学方法对其进行表征,以及研究其在子宫颈癌细胞系SiHa中的细胞摄取情况。
通过壳聚糖与三聚磷酸钠(TPP)的离子凝胶化方法合成壳聚糖纳米颗粒。此外,通过动态光散射(DLS)、紫外可见分光光度计、差示扫描量热法(DSC)、液相色谱-质谱联用(LCMS)和乳酸脱氢酶(LDH)测定对壳聚糖纳米颗粒和负载姜黄素的壳聚糖纳米颗粒的内部结构进行表征。
研究表明,与游离姜黄素相比,负载姜黄素的壳聚糖纳米颗粒在SiHa细胞中的摄取增加,而壳聚糖纳米颗粒在SiHa细胞系中未显示出任何显著摄取。在子宫颈癌细胞系如SiHa、CaSki和HeLa中,与天然姜黄素相比,负载姜黄素的壳聚糖纳米颗粒释放更多的乳酸且ATP水平更低。
因此,基于壳聚糖的姜黄素纳米颗粒可作为一种有效的载体/递送剂用于子宫颈癌治疗中的药物靶向。
