- Title: Automatic design of novel potential 3CL$^{\text{pro}}$ and
PL$^{\text{pro}}$ inhibitors
- Abstract summary: We propose a general molecule optimization framework, Molecular Neural Assay Search (MONAS)
MONAS consists of three components: a property predictor which identifies molecules with specific desirable properties, an energy model which approximates the statistical similarity of a given molecule to known training molecules, and a molecule search method.
In this work, these components are instantiated with graph neural networks (GNNs), Deep Energy Estorimat Networks (DEEN) and Monte Carlo tree search (MCTS)

- Abstract: With the goal of designing novel inhibitors for SARS-CoV-1 and SARS-CoV-2, we
propose the general molecule optimization framework, Molecular Neural Assay
Search (MONAS), consisting of three components: a property predictor which
identifies molecules with specific desirable properties, an energy model which
approximates the statistical similarity of a given molecule to known training
molecules, and a molecule search method. In this work, these components are
instantiated with graph neural networks (GNNs), Deep Energy Estimator Networks
(DEEN) and Monte Carlo tree search (MCTS), respectively. This implementation is
used to identify 120K molecules (out of 40-million explored) which the GNN
determined to be likely SARS-CoV-1 inhibitors, and, at the same time, are
statistically close to the dataset used to train the GNN.

This work explores the challenging problem of molecule design by framing it as a conditional generative modeling task.
We propose a novel generative model comprising three components: (1) a latent vector with a learnable prior distribution; (2) a molecule generation model based on a causal Transformer, which uses the latent vector as a prompt; and (3) a property prediction model that predicts a molecule's target properties and/or constraint values using the latent prompt.
