摘要

由于质子化胺基对壳聚糖链进行了高度化学修饰,使其能够作为阴离子聚合物和细胞膜与许多带负电荷的表面发生反应,从而成为一种在医疗和制药应用中极具吸引力的材料。在壳聚糖链上加入离子碘(I- 和 IO3-)是通过离子凝胶化成功获得壳聚糖-碘纳米粒子(CSNPs-I 和 CSNPs-IO3)的直接方法。根据 SEM 和 DLS 技术,CSNPs-I 和 CSNPs-IO3 纳米粒子(NPs)呈现半球形形态,大小约为 30-70 nm,与壳聚糖 NPs 相似。XRD 表征显示,CSNPs 和 CSNPs-I 的结晶度指数(CI)并无明显差异,分别为 48.4% 和 49.3%,但 CSNPs-IO3 的结晶度指数降至 43.85%。评估了壳聚糖和碘改性壳聚糖纳米粒子(CSNPs-I 和 CSNPs-IO3)对人类肿瘤细胞的细胞毒性作用,24 小时内,CSNPs-I 和 CSNPs-IO3 的浓度范围从 0.15 mg/mL 到 0.其中 CSNPs-IO3 对肺癌 A549 的存活率较低,其次是宫颈癌 HeLa 细胞,最后是乳腺癌 MDA-MB-231。这项研究为壳聚糖-碘 NPs 在医疗领域的应用提供了可能性。

Synthesis and Characterization of Iodinated Chitosan Nanoparticles and Their Effects on Cancer Cells.

The high degree of chemical modification of the chitosan chains due to protonated amine groups allows them to react with many negatively charged surfaces as anionic polymers and cell membranes, resulting in an attractive material for medical and pharmaceutics applications. Incorporating ionic iodine (I- and IO3 -) on chitosan chains is a direct way to successfully obtain chitosan-iodine nanoparticles (CSNPs-I and CSNPs-IO3) through ionic gelation. The nanoparticles (NPs) present a hemispherical morphology with sizes around 30-70 nm for CSNPs-I and CSNPs-IO3, similar to chitosan NPs, in accordance with SEM and DLS techniques. The XRD characterization did not show noticeable differences in the crystallinity index (CI) for CSNPs and CSNPs-I, 48.4 and 49.3%, respectively, but for CSNPs-IO3, the CI decreased to 43.85%. The cytotoxic effects on human tumor cells of chitosan and iodine-modified chitosan nanoparticles (CSNPs-I and CSNPs-IO3) were evaluated for 24 h in a range from 0.15 mg/mL to 0.95 mg/mL concentrations, where CSNPs-IO3 presented the lower viability for lung cancer A549, followed by cervical cancer HeLa cell and finally breast cancer MDA-MB-231, with a weight content of iodate ion in a range of 8.7 to 15 μg. This work presents the possibility of exploring chitosan-iodine NPs in medical applications.
