Abstract

Glycyrrhiza glabra Linn (liquorice) has been widely used for therapeutic purposes to treat digestive disorders, immunomodulatory disorders, inflammatory disorders, diabetes, viral infections, and cancer. Liquorice contains a wide variety of bioactive compounds, including glycyrrhizin, flavonoids, and terpenoids. Several factors compromise their therapeutic efficacy, such as poor pharmacokinetic profiles and physicochemical properties. Therefore, to improve its overall effectiveness, liquorice solid dispersion (LSD) was incorporated into biopolymer-based guar gum-grafted-2-acrylamido-2-methylpropane sulfonic acid (Guar gum-g-AMPS) hydrogels designed for controlled delivery via the oral route and characterized. The qualitative analysis of LSD revealed 51 compounds. Hydrogel structural properties were assessed for their effect on swelling and release. The highest swelling ratio (6413 %) and drug release (84.12 %) occurred at pH 1.2 compared to pH 7.4 (swelling ratio of 2721 % and drug release of 79.36 %) in 48 h. The hydrogels exhibited high porosity (84.23 %) and biodegradation (9.30 % in 7 days). In vitro hemolysis tests have demonstrated the compatibility of the hydrogel with blood. CCK-8 assay confirmed the biocompatibility of the synthesized hydrogel using osteoblasts and RIN-m5f cells. LSD exhibited good anti-inflammatory activity when loaded into hydrogels after being subjected to protein denaturation experiments. Moreover, LSD-loaded hydrogels have good antioxidant and antibacterial properties.

摘要

甘草(甘草)已被广泛用于治疗消化疾病、免疫调节障碍、炎症性疾病、糖尿病、病毒感染和癌症等治疗目的。甘草含有多种生物活性化合物,包括甘草酸、类黄酮和萜类化合物。有几个因素会影响它们的治疗效果,例如药代动力学特性和物理化学性质不佳。因此,为了提高其整体效果,将甘草固体分散体(LSD)掺入基于生物聚合物的瓜尔胶接枝-2-丙烯酰胺-2-甲基丙磺酸(瓜尔胶-g-AMPS)水凝胶中,设计用于通过口服途径进行控释,并对其进行了表征。LSD 的定性分析显示了 51 种化合物。评估了水凝胶的结构特性对其溶胀和释放的影响。在 48 小时内,pH 1.2 时的溶胀比(6413%)和药物释放(84.12%)最高,而 pH 7.4 时的溶胀比(2721%)和药物释放(79.36%)。水凝胶具有高孔隙率(84.23%)和生物降解性(7 天内 9.30%)。体外溶血试验表明水凝胶与血液相容。CCK-8 测定法证实了合成水凝胶对成骨细胞和 RIN-m5f 细胞的生物相容性。在进行蛋白质变性实验后,将 LSD 负载到水凝胶中时,其表现出良好的抗炎活性。此外,LSD 负载的水凝胶具有良好的抗氧化和抗菌性能。
