All acute and chronic wound management strategies have limitations. Therefore, there is an urgent need to develop new treatment options for wound healing. Hydrogels based on natural polymers offer advantages in wound management because they can reduce patients' pain, fight infection, and carry targeted drugs to speed up the healing process. In this study, we aimed to develop and investigate an alginate-grafted N-vinylcaprolactam-based matrix for a modified release of dexketoprofen (DEX), which is potentially useful in wound healing. Free radical polymerization and grafted techniques were used to prepare thermo-responsive hydrogels. The obtained hydrogels, unloaded hydrogel (HY) and dexketoprofen-loaded hydrogel (DEXHY), were characterized and analyzed. The concentration of DEX encapsulated in the polymer matrix was 4 mg/mL. The IC50 values found for the samples tested by us were 607.4 µg/mL for HY, 950.4 µg/mL for DEXHY, and 2239 µg/mL for DEX. The average value of cell viability (%) after the exposure of cells to DEXHY hydrogel was 75.4%. DEXHY exhibited a very good in vitro wound closure rate, given its ability to modify DEX release kinetics. The hydrogel developed in this study has shown considerable potential to facilitate and even accelerate wound healing, including surgical wounds, by inhibiting the overexpressed inflammation process.
所有急性和慢性伤口管理策略都有局限性。因此,迫切需要开发新的伤口愈合治疗方案。基于天然聚合物的水凝胶在伤口管理方面具有优势,因为它们可以减轻患者疼痛、对抗感染并携带靶向药物以加速愈合过程。在本研究中,我们旨在开发并研究一种基于藻酸盐接枝N-乙烯基己内酰胺的基质,用于酮洛芬(DEX)的控释,这在伤口愈合中可能有用。采用自由基聚合和接枝技术制备热响应性水凝胶。对所获得的水凝胶,即未负载水凝胶(HY)和负载酮洛芬的水凝胶(DEXHY)进行了表征和分析。聚合物基质中包封的DEX浓度为4mg/mL。我们测试的样品的IC50值分别为:HY为607.4μg/mL,DEXHY为950.4μg/mL,DEX为2239μg/mL。细胞暴露于DEXHY水凝胶后,细胞活力(%)的平均值为75.4%。DEXHY由于能够改变DEX的释放动力学,因此表现出非常好的体外伤口闭合率。本研究中开发的水凝胶已显示出通过抑制过度表达的炎症过程来促进甚至加速伤口愈合(包括手术伤口)的巨大潜力。
