Where AI meets the experiment

A weekly exploration of AI in chemistry.
The research, the methods, the significance.

Inside this edition

Molecular discovery / analysis

A mass spectrum still leaves a choice

DiffMS generates molecular candidates from a spectrum and a known formula. Its benchmark gains are useful partly because the remaining ambiguity is measurable.

Molecular discovery / analysis

Adding orbitals to the molecular graph

Stereoelectronic features can enrich a molecular representation. A learned surrogate makes the extra information accessible while introducing another prediction boundary.

Synthesis & automation / analysis

Choosing a plate, not just an experiment

Minerva makes parallel reaction optimisation a problem of batches and competing objectives. The analyst still has to define what success means.

Synthesis & automation / analysis

Few-shot selectivity still needs a history

A meta-learning study asks how prior reaction data can help classify asymmetric hydrogenations when a new task has few examples.

Synthesis & automation / analysis

Finding an enzyme for the substrate in hand

CATNIP links measured reaction compatibility to chemical and protein similarity. Its useful output is a ranked starting point for testing.

Molecular discovery / analysis

The test set is part of the question

DataSAIL makes molecular similarity an explicit part of evaluation. Its addendum also shows why no split should be treated as a universal answer.

Molecular discovery / analysis

What a bag of atoms can teach a benchmark

A 2024 study asks how much molecular topology a benchmark really demands, and tests a set-based alternative to familiar graph models.

Synthesis & automation / analysis

When a highlighted atom becomes a hypothesis

An arene-selectivity model offers clues about where chemistry happens. A clue becomes more useful when a separate calculation can challenge it.

Molecular discovery / analysis

Zero-shot generation is not data-free

SiMGen generates molecular structures through local similarity. Its use of pretrained components makes the meaning of zero-shot worth spelling out.

Medicinal Chemistry / analysis

Count the compounds before the hit rate

Nine synthesized A2A ligands make a useful case for reporting the choices between a generated library and an experimental claim.

Medicinal Chemistry / analysis

A potency gain needs a chemical history

A MAGL optimization study joins reaction prediction to compound design. Its most useful record is the route from a proposed substitution to a measured series.

Pharmacology / analysis

An antibody must reach its target

A simulation-plus-learning study asks which combinations of exposure and target biology sustain engagement.

Pharmacology / analysis

Who chooses the compartments?

Automated pharmacokinetic modelling makes the search more explicit. Its useful output is a defensible model of exposure.

Pharmacology / analysis

A drug response needs a clock

XPert treats concentration and time as part of the prediction, bringing cellular response closer to a pharmacological question.

Molecular discovery / analysis

Generating a molecule is the beginning

SmileyLlama makes molecular generation steerable in words. The next question is how a proposed structure earns experimental trust.
