SynFlowNet: Design of Diverse and Novel Molecules with Synthesis Constraints

ICLR 2025spotlight

Generative models see increasing use in computer-aided drug design. However, while performing well at capturing distributions of molecular motifs, they often produce synthetically inaccessible molecules. To address this, we introduce SynFlowNet, a GFlowNet model whose action space uses chemical reac…

Retro-fallback: retrosynthetic planning in an uncertain world

ICLR 2024poster

Retrosynthesis is the task of planning a series of chemical reactions to create a desired molecule from simpler, buyable molecules. While previous works have proposed algorithms to find optimal solutions for a range of metrics (e.g. shortest, lowest-cost), these works generally overlook the fact tha…

RetroBridge: Modeling Retrosynthesis with Markov Bridges

ICLR 2024spotlight

Retrosynthesis planning is a fundamental challenge in chemistry which aims at designing multi-step reaction pathways from commercially available starting materials to a target molecule. Each step in multi-step retrosynthesis planning requires accurate prediction of possible precursor molecules given…

Retrosynthetic Planning with Dual Value Networks

ICML 2023poster

Retrosynthesis, which aims to find a route to synthesize a target molecule from commercially available starting materials, is a critical task in drug discovery and materials design. Recently, the combination of ML-based single-step reaction predictors with multi-step planners has led to promising re…

Learning to Extend Molecular Scaffolds with Structural Motifs

ICLR 2022poster

Recent advancements in deep learning-based modeling of molecules promise to accelerate in silico drug discovery. A plethora of generative models is available, building molecules either atom-by-atom and bond-by-bond or fragment-by-fragment. However, many drug discovery projects require a fixed scaffo…

FS-Mol: A Few-Shot Learning Dataset of Molecules

NeurIPS 2021poster

Small datasets are ubiquitous in drug discovery as data generation is expensive and can be restricted for ethical reasons (e.g. in vivo experiments). A widely applied technique in early drug discovery to identify novel active molecules against a protein target is modelling quantitative structure-act…

Barking up the right tree: an approach to search over molecule synthesis DAGs

NeurIPS 2020spotlight

When designing new molecules with particular properties, it is not only important what to make but crucially how to make it. These instructions form a synthesis directed acyclic graph (DAG), describing how a large vocabulary of simple building blocks can be recursively combined through chemical reac…

A Model to Search for Synthesizable Molecules

NeurIPS 2019poster

Deep generative models are able to suggest new organic molecules by generating strings, trees, and graphs representing their structure. While such models allow one to generate molecules with desirable properties, they give no guarantees that the molecules can actually be synthesized in practice. We…

Exploring Deep Recurrent Models with Reinforcement Learning for Molecule Design

ICLR 2018workshop

The design of small molecules with bespoke properties is of central importance to drug discovery. However significant challenges yet remain for computational methods, despite recent advances such as deep recurrent networks and reinforcement learning strategies for sequence generation, and it can be…
