When to use it

Rowan is a cloud-native molecular modeling and medicinal-chemistry workflow platform with a Python API. Use for pKa and macropKa prediction, conformer and tautomer ensembles, docking and analogue docking, protein-ligand cofolding, MSA generation, molecular dynamics, permeability, descriptor workflows, and related small-molecule or protein modeling tasks. Ideal for programmatic batch screening, multi-step chemistry pipelines, and workflows that would otherwise require maintaining local HPC/GPU infrastructure.

Example requests

Ask your agent in plain language, for example:
  • “How do I get the pKa of aspirin with Rowan?”
  • “I have 40 analogues of my kinase lead in analogs.csv (SMILES column) and a prepared receptor, kinase.pdb, with a co-crystal ligand as reference. I tried passing the SMILES strings straight into the analogue docking workflow and got a ValueError before submission. Fix this and run the whole series on Rowan, then pull out the best pose and score for each.”
  • “I need to know how my carboxylic acid/amine drug candidate will be charged across pH 0-14, and whether it will cross membranes and how soluble it is at pH 7.4. I don’t want to set up any local compute. How would I do that programmatically for a few hundred compounds?”

Install

In Claude Code you can also add the marketplace with /plugin marketplace add KalarisLabs/research-agent-skills and install the whole chemistry-and-drug-discovery category with /plugin install chemistry-and-drug-discovery@research-agent-skills.
