Molecular substructure graph attention network for molecular property identification in drug discovery

作者:

Highlights:

• We propose to use a structural feature extraction scheme including 3 types of features (raw + tree decomposition + ECFP).

• We design a framework including several graph attention convolutional (GAC) blocks and deep neural network (DNN) blocks to process the above structural features.

• We design a readout block based on gated recurrent units (GRU). The readout blocks collaborate with the GAC blocks to obtain molecular embeddings.

• We visualize molecules and mark the important atoms with attention scores of MSSGAT, which can be a good reference for subsequent drug development.
