Abstract

Kinase profiling is an essential step in both hit identification and selectivity evaluation. Since in vitro testing of large chemical libraries is costly and time-consuming, a computational approach can be applied to narrow down the reasonable chemical space. In this work, we collected data from several sources and prepared a curated, comprehensive database for training machine learning (ML) models to predict selectivity towards 75 kinases. We demonstrated the usefulness of this database by preparing several ML models with various molecular representations and model architectures. Among these, a graph neural network-based model enhanced by utilizing 3D pharmacophore ensembles showed the best performance. Finally, the developed model was applied to a library of in-stock compounds to facilitate kinase-focused drug discovery.

Graphical abstract

通过将图神经网络应用于三维药效团集合,提高虚拟激酶谱分析的准确性。
激酶谱分析是命中识别和选择性评价的重要步骤。由于大型化学文库的体外测试既昂贵又耗时,因此可以采用计算方法来缩小合理的化学空间。在这项工作中,我们从多个来源收集数据,并准备了一个精心策划的综合数据库,用于训练机器学习(ML)模型,以预测对75种激酶的选择性。我们通过准备几个具有不同分子表示和模型架构的ML模型来证明该数据库的有用性。其中,利用三维药效团集成增强的基于图神经网络的模型表现出最好的性能。最后,将开发的模型应用于库存化合物库,以促进以激酶为重点的药物发现。
