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

1 code implementation NeurIPS 2020 John Bradshaw, Brooks Paige, Matt J. Kusner, Marwin H. S. Segler, José Miguel Hernández-Lobato

When designing new molecules with particular properties, it is not only important what to make but crucially how to make it.

RetroGNN: Approximating Retrosynthesis by Graph Neural Networks for De Novo Drug Design

no code implementations25 Nov 2020 Cheng-Hao Liu, Maksym Korablyov, Stanisław Jastrzębski, Paweł Włodarczyk-Pruszyński, Yoshua Bengio, Marwin H. S. Segler

A natural idea to mitigate this problem is to bias the search process towards more easily synthesizable molecules using a proxy for synthetic accessibility.

World Programs for Model-Based Learning and Planning in Compositional State and Action Spaces

no code implementations30 Dec 2019 Marwin H. S. Segler

We highlight a recent application, and propose a challenge for the community to assess world program-based planning.

A Model to Search for Synthesizable Molecules

1 code implementation NeurIPS 2019 John Bradshaw, Brooks Paige, Matt J. Kusner, Marwin H. S. Segler, José Miguel Hernández-Lobato

Deep generative models are able to suggest new organic molecules by generating strings, trees, and graphs representing their structure.

Generating Molecules via Chemical Reactions

no code implementations ICLR Workshop DeepGenStruct 2019 John Bradshaw, Matt J. Kusner, Brooks Paige, Marwin H. S. Segler, José Miguel Hernández-Lobato

We therefore propose a new molecule generation model, mirroring a more realistic real-world process, where reactants are selected and combined to form more complex molecules.

GuacaMol: Benchmarking Models for De Novo Molecular Design

2 code implementations22 Nov 2018 Nathan Brown, Marco Fiscato, Marwin H. S. Segler, Alain C. Vaucher

De novo design seeks to generate molecules with required property profiles by virtual design-make-test cycles.

Learning to Plan Chemical Syntheses

no code implementations14 Aug 2017 Marwin H. S. Segler, Mike Preuss, Mark P. Waller

We anticipate that our method will accelerate drug and materials discovery by assisting chemists to plan better syntheses faster, and by enabling fully automated robot synthesis.

Generating Focussed Molecule Libraries for Drug Discovery with Recurrent Neural Networks

5 code implementations5 Jan 2017 Marwin H. S. Segler, Thierry Kogej, Christian Tyrchan, Mark P. Waller

In de novo drug design, computational strategies are used to generate novel molecules with good affinity to the desired biological target.

Modelling Chemical Reasoning to Predict Reactions

no code implementations25 Aug 2016 Marwin H. S. Segler, Mark P. Waller

The ability to reason beyond established knowledge allows Organic Chemists to solve synthetic problems and to invent novel transformations.
