摘要

为了补充实验研究,我们进行了硅分子对接,以获取和了解一些实验性强效抗癫痫化合物在GABAT酶(癫痫障碍的一种病原体)结合位点上的相互作用结合能动力学。本研究使用Pyrx多用途仿真软件中的Autoduck vina对接选项进行对接仿真。采用基于结构的药物技术设计了4种抗癫痫候选药物(抗癫痫药物)。所有设计的候选AED都表现出稳定的结合相互作用能。在所设计的四种化合物中,9-癸基-8-甲基-6-(1h - 1,2,4 -三唑-1-基)- 9h -嘌呤与GABAT的结合能较好。该化合物的停泊能评分(7.8Kcal/mol)优于标准抗癫痫化合物卡马西平(-6.5kcal/mol)和丙戊酸酯(-4.5kcal/mol)的结合能评分。通过这种水平的相互作用,该候选药物可以更好地结合酶的结合位点。此外,药代动力学研究表明,所有设计的候选AED药物易于合成、吸收、分布、代谢和排出体外。因此,该候选药物可被合成并有效用于癫痫疾病的治疗和管理。

Molecular Docking, Design and Pharmacokinetics Study of Some Anti-Epilepsy Compounds
To complement experimental study, in-silico molecular docking was carried out to access and understand the interacting binding energy dynamism of some experimental potent anti-epilepsy compounds on the GABAT enzyme’s (A causative agent for epilepsy disorder) binding site. The Autoduck vina docking option of Pyrx multipurpose simulation software was used in this study to perform docking simulations. Four anti-epilepsy drug (AED) candidates was designed (Anti-epilepsy disorders) through a structural based drug technique. All the designed AED candidates shows stable binding interaction energies. Out of the four designed compounds, 9-decyl-8-methyl-6-(1H-1, 2, 4-triazol-1-yl)-9H-purine shows better binding energy with GABAT. The docked energy score of the compound (7.8Kcal/mole) was better than the binding energy scores of the standard anti-epilepsy compounds, Carbamazepine (-6.5kcal/mole) and Valproate (-4.5kcal/mole). With this level of interaction, this drug candidate could bind better on the enzyme’s binding site. Also, the pharmacokinetic properties investigation revealed that all designed AED candidates could be synthesized easily, absorbed, distributed, metabolized and excreted from the body. Therefore, this drug candidate could be synthesized and used effectively for the treatment and management of epilepsy disorder.
