Flavonoids demonstrate beneficial effects on human health because flavonoids contain important biological properties. Kaempferol is a flavonol, type of flavonoid found in eatable plants and in plants usually employed in ancient drugs (, Tilia spp., fern genus spp. and gingko etc.). Some medicinal studies have shown that the use of foods full of kaempferol decreases the risk of many (cancer, vascular) diseases. All the data of 50 kaempferol derivatives were collected from PubChem database. Through Schrödinger software, 3D-QSAR study was performed for 50 compounds by using method of field base. Conformer of kaempferol derivatives was docked against anti-diabetic, anti-microbial co-crystal structures and protein. To monitor the best anti-diabetic and antibacterial agent, particular kaempferol derivatives were downloaded from PubChem database. Virtual screening by molecular docking provided four lead compounds with four different proteins. These hit compounds were found to be potent inhibitor for diabetic enzymes alpha-amylase and DPP IV and had the potential to suppress DNA gyrase and dihydrofolate reductase synthesis. Molecular dynamic simulation of docked complexes evaluates the value of root mean square fluctuation by iMOD server. Kaempferol 3-O-alpha-L-(2, 3-di-Z-p-coumaroyl) rhamnoside compound used as anti-diabetic and kaempferol 3-O-gentiobioside as antibacterial with good results can be used for drug discovery.
黄酮类化合物对人体健康具有有益作用,因为它们具有重要的生物学特性。山奈酚是一种黄酮醇,属于黄酮类化合物,存在于可食用植物以及古代药物中常用的植物(如椴树属、蕨类属植物和银杏等)中。一些医学研究表明,食用富含山奈酚的食物可降低多种(癌症、血管)疾病的风险。从PubChem数据库收集了50种山奈酚衍生物的所有数据。通过薛定谔软件,采用基于场的方法对50种化合物进行了3D-QSAR研究。将山奈酚衍生物的构象异构体与抗糖尿病、抗微生物共晶体结构和蛋白质进行对接。为了筛选出最佳的抗糖尿病和抗菌剂,从PubChem数据库下载了特定的山奈酚衍生物。通过分子对接进行虚拟筛选,得到了四种与四种不同蛋白质结合的先导化合物。这些命中化合物被发现是糖尿病酶α-淀粉酶和二肽基肽酶IV的有效抑制剂,并且有可能抑制DNA回旋酶和二氢叶酸还原酶的合成。对接复合物的分子动力学模拟通过iMOD服务器评估均方根波动值。山奈酚3-O-α-L-(2,3-二-Z-p-香豆酰基)鼠李糖苷化合物用作抗糖尿病药物,山奈酚3-O-龙胆二糖苷用作抗菌药物,效果良好,可用于药物研发。
