Wild (Fabaceae) barks are traditionally used in the treatment of diabetes and wounds. Therefore, the objective of the present study was to evaluate the wound healing potential of the alcoholic extract of (EAC) in streptozotocin-induced diabetic mice.
EAC was first subjected to phytochemical estimations and standardization using (-) epicatechin as marker with the help of HPLC. Diabetes was induced in mice using streptozotocin and the wound healing potential of EAC was evaluated using excision and incision wound models on topical and oral treatment. Various biochemical parameters, antioxidants, cytokine profiling, VEGF, and histopathological examination were also performed. Further, molecular docking studies were performed using ligand (-) epicatechin on human inducible nitric oxide synthase.
Phytochemically, EAC showed the presence of tannins, flavonoids, phenolic compounds, and saponins, while the content of (-) epicatechin was reported to be 7.81% w/w. The maximum healing of wounds (91.84 ± 1.10%) was observed in mice treated with a combination of both topical (10% gel) and oral (extract at 200 mg/kg) followed by topically and orally treated groups respectively after 14 days of treatment. These groups also showed significant restoration of altered biochemical parameters, antioxidant enzymes and cytokines. The molecular docking studies confirmed the role of (-) epicatechin in stabilizing the human inducible nitric oxide synthase with inhibitor showing binding energy of -8.31 kcal/mol. The present study confirmed the role of (-) epicatechin as a major marker in diabetic wound healing potential of
豆科野生树皮传统上用于治疗糖尿病和伤口。因此,本研究的目的是评估刺果甘草乙醇提取物(EAC)对链脲佐菌素诱导的糖尿病小鼠的伤口愈合潜力。
首先对EAC进行植物化学评估,并借助高效液相色谱法以(-)表儿茶素为标记物进行标准化。用链脲佐菌素诱导小鼠患糖尿病,并通过切除和切开伤口模型评估EAC在局部和口服治疗时的伤口愈合潜力。还进行了各种生化参数、抗氧化剂、细胞因子分析、血管内皮生长因子(VEGF)以及组织病理学检查。此外,使用配体(-)表儿茶素对人诱导型一氧化氮合酶进行分子对接研究。
从植物化学角度来看,EAC含有单宁、黄酮类化合物、酚类化合物和皂苷,据报道(-)表儿茶素的含量为7.81%(w/w)。在接受局部(10%凝胶)和口服(200mg/kg提取物)联合治疗的小鼠中观察到伤口愈合程度最高(91.84±1.10%),其次是分别在局部和口服治疗14天后的治疗组。这些组还显示出改变的生化参数、抗氧化酶和细胞因子有显著恢复。分子对接研究证实了(-)表儿茶素在稳定人诱导型一氧化氮合酶方面的作用,抑制剂的结合能为-8.31千卡/摩尔。本研究证实了(-)表儿茶素作为刺果甘草糖尿病伤口愈合潜力主要标志物的作用 。
