Diabetes mellitus is becoming an important public health challenge worldwide and especially in developing nations. About 8.8 percent of the world adult population has been reported to have diabetes. Glutamine-fructose-6-phosphate amidotransferase 1 (GFAT1) catalyses the first committed step in the pathway for biosynthesis of hexosamines in mammals, and its inhibition has been thought to prevent hyperglycaemia. Dipeptidyl peptidase-4 (DPP-4), on the other hand, degrades hormone glucagon-like peptide-1 (GLP-1), an enzyme that plays a major role in the enhancement of glucose-dependent insulin secretion, making these two proteins candidate targets for diabetes. To find potential inhibitors of DPP-4 and GFAT1 from Anacardium occidentale using a computational approach, glide XP (extra precision) docking, Induced Fit Docking (IFD), Binding free energy of the compounds were determined against prepared crystal structure of DPP-4 and GFAT1 using the Maestro molecular interface of Schrödinger suites. The Lipinski's rule of five (RO5) and ADME properties of the compounds were assessed. Predictive models for both protein targets were built using AutoQSAR. This study identified 8 hit compounds. Most of these compounds passed the RO5 and were within the recommended range for defined ADME parameters. In addition, the predicted pIC50 for the hit compounds were promising. The results obtained from the present study can be used to design an antidiabetic drug.

糖尿病正成为全球尤其是发展中国家一项重要的公共卫生挑战。据报道,全球约8.8%的成年人口患有糖尿病。谷氨酰胺-果糖-6-磷酸酰胺转移酶1(GFAT1)催化哺乳动物中己糖胺生物合成途径的第一步,其抑制作用被认为可预防高血糖症。另一方面,二肽基肽酶-4(DPP-4)可降解激素胰高血糖素样肽-1(GLP-1),该酶在增强葡萄糖依赖性胰岛素分泌中起主要作用,这使得这两种蛋白质成为糖尿病的候选靶点。为了通过计算方法从腰果中寻找DPP-4和GFAT1的潜在抑制剂,使用薛定谔套件的Maestro分子界面,针对制备好的DPP-4和GFAT1晶体结构,确定了化合物的Glide XP(高精度)对接、诱导契合对接(IFD)和结合自由能。评估了化合物的Lipinski五规则(RO5)和ADME性质。使用AutoQSAR构建了两种蛋白质靶点的预测模型。本研究鉴定出8种有活性的化合物。这些化合物中的大多数通过了RO5标准,并且在定义的ADME参数推荐范围内。此外,有活性的化合物的预测pIC50很有前景。本研究获得的结果可用于设计抗糖尿病药物。
