Drug targets are the main focus of drug discovery due to their key role in disease pathogenesis. Computational approaches are widely applied to drug development because of the increasing availability of biological molecular datasets. Popular generative approaches can create new drug molecules by learning the given molecule distributions. However, these approaches are mostly not for target-specific drug discovery. We developed an energy-based probabilistic model for computational target-specific drug discovery. Results show that our proposed TagMol can generate molecules with similar binding affinity scores as molecules. GAT-based models showed faster and better learning relative to Graph Convolutional Network baseline models.
由于药物靶点在疾病发病机制中起关键作用,因此它是药物研发的主要焦点。由于生物分子数据集的可用性不断增加,计算方法被广泛应用于药物开发。流行的生成方法可以通过学习给定的分子分布来创建新的药物分子。然而,这些方法大多不是用于针对特定靶点的药物发现。我们开发了一种基于能量的概率模型用于计算针对特定靶点的药物发现。结果表明,我们提出的TagMol可以生成与分子具有相似结合亲和力分数的分子。相对于图卷积网络基线模型,基于门控注意力网络(GAT)的模型显示出更快且更好的学习效果。
