“…In the past decade, the rapid development and wide application of artificial intelligence (AI) techniques have shown its great success in many areas, especially in computer vision and natural language processing (NLP). With the increasing amassment of accessible drug data, AI techniques are being introduced into drug discovery, and a number of AI-based models for molecular property prediction have been developed ( Jiménez et al , 2018 ; Liew et al , 2009 ; Melville et al , 2009 ; Peng et al , 2020 ). Particularly, with the development of graph neural networks (GNNs) in recent years ( Kipf and Welling, 2017 ; Veličković et al , 2018 ), graph-based molecular property prediction is becoming a hot research topic ( Coley et al , 2017 ; Duvenaud et al , 2015 ; Gilmer et al , 2017 ; Kearnes et al , 2016 ; Xiong et al , 2020 ; Zhou and Li, 2017 ).…”

“…RNN based methods have been widely used for tasks in absorption category and Tox21 datasets (Table S1). TOP [112] achieved an excellent performance in toxicity prediction using Tox21 dataset (mean AUC-ROC: 0.950) by integrating shallow representation on SMILES into biGRU in combination with some molecular descriptors (logP, MW and TPSA). By incorporating the physiochemical properties, TOP resulted in 0.195 performance gain in terms of AUC-ROC.…”

“…logP (partition coefficient) and TPSA (total polar surface area) are related to the solubility of a compound in aqueous solutions and the presence of specific structural features such as the number of rings is related to carcinogenesis [205] . TOP [112] leveraged logP, molecular weight, and TPSA to the independent fully connected layers on the word embeddings of SMILES along with biGRU to learn chemical structures. Addition of physico-chemical properties selected by genetic algorithm to biGRU featurization provided 0.195 of improvement in AUC-ROC to toxicity prediction tasks.…”

“…The most commonly used representations of drugs and targets are one-dimensional (1D) sequences such as Simplified Molecular Input Line Entry Specification (SMILES) strings for drugs and amino acid sequences for targets ( Karimi et al , 2019 ; Liu et al , 2020 ; Peng et al , 2020 ; Tsubaki et al , 2019 ; Zheng et al , 2020 ). The models with 1D sequences as input generally use Convolutional Neural network (CNN), Recurrent Neural Network (RNN), Long Short-Term Memory (LSTM) blocks or Gated Recurrent Unit (GRU) blocks to extract drug and target features.…”
