摘要
背景:蛋白质-配体配合物的原子坐标分析可以提供三维数据来生成计算模型,以评估结合亲和力和热力学状态函数。机器学习技术的应用可以创建模型来评估蛋白质-配体的势能和结合亲和力。与对接程序中可用的经典评分功能相比,这些方法显示出出众的预测性能。 目标:我们的目的是审查SAnDReS程序的开发和应用。我们描述了机器学习模型的创建,以评估蛋白质-配体复合物的结合亲和力。 方法:SAnDReS实现scikit-learn库中可用的机器学习方法。该程序可从https://github.com/azevedolab/sandres下载。 SAnDReS使用晶体结构,结合和热力学数据来创建目标评分功能。 结果:程序SAnDReS在诸如凝血因子Xa,细胞周期蛋白依赖性激酶和HIV-1蛋白酶等药物靶标上的最新应用能够创建靶向评分功能,以预测这些蛋白的抑制作用。这些目标模型的表现优于经典评分功能。 结论:在这里,我们回顾了通过应用SAnDReS程序预测绑定亲和力的机器学习评分功能的发展。我们的研究表明,与AutoDock4,Molegro Virtual Docker和AutoDock Vina等程序中提供的经典评分功能相比,SAnDReS开发的模型具有出色的预测性能。
