Abstract

Novel eco-friendly fibrous materials with complex activities from cellulose acetate and cellulose acetate/polyethylene glycol (CA,PEG) containing 5-chloro-8-hydroxyquinoline as a model drug were obtained by electrospinning. Several methods, including scanning electron microscopy, X-ray diffraction analysis, ultraviolet-visible spectroscopy, water contact angle measurements, and mechanical tests, were utilized to characterize the obtained materials. The incorporation of PEG into the fibers facilitated the drug release. The amounts of the released drug from CA/5-Cl8Q and CA,PEG/5-Cl8Q were 78 ± 3.38% and 86 ± 3.02%, respectively (for 175 min). The antibacterial and antifungal activities of the obtained materials were studied. The measured zones of inhibition of CA/5-Cl8Q and CA,PEG/5-Cl8Q mats were 4.0 ± 0.18 and 4.5 ± 0.2 cm against and around 4.0 ± 0.15 and 4.1 ± 0.22 cm against , respectively. The complete inhibition of the growth was detected. The cytotoxicity of the obtained mats was tested toward HeLa cancer cells, SH-4 melanoma skin cells, and mouse BALB/c 3T3 fibroblasts as well. The CA/5-Cl8Q and CA,PEG/5-Cl8Q materials exhibited anticancer activity and low normal cell toxicity. Thus, the obtained fibrous materials can be suitable candidates for wound dressing applications and for application in local cancer treatment.

摘要

通过静电纺丝制备了含有5-氯-8-羟基喹啉作为模型药物的新型环保纤维材料,该材料由醋酸纤维素和醋酸纤维素/聚乙二醇(CA,PEG)组成,具有多种复合活性。采用了几种方法对所得材料进行表征,包括扫描电子显微镜、X射线衍射分析、紫外可见光谱、水接触角测量和力学测试。将PEG掺入纤维中有助于药物释放。CA/5-Cl8Q和CA,PEG/5-Cl8Q释放的药物量分别为78±3.38%和86±3.02%(175分钟时)。研究了所得材料的抗菌和抗真菌活性。CA/5-Cl8Q和CA,PEG/5-Cl8Q垫对金黄色葡萄球菌的抑菌圈分别为4.0±0.18和4.5±0.2厘米,对白色念珠菌的抑菌圈分别约为4.0±0.15和4.1±0.22厘米。检测到对白色念珠菌生长的完全抑制。还测试了所得垫对HeLa癌细胞、SH-4黑色素瘤皮肤细胞和小鼠BALB/c 3T3成纤维细胞的细胞毒性。CA/5-Cl8Q和CA,PEG/5-Cl8Q材料表现出抗癌活性和低正常细胞毒性。因此,所得纤维材料可成为伤口敷料应用和局部癌症治疗应用的合适候选材料。
