Why ADMET matters before you synthesize anything
ADMET — absorption, distribution, metabolism, excretion, and toxicity — is what separates a molecule that binds a target on paper from one that could actually become a drug. A compound can have excellent predicted potency and still fail because it's poorly absorbed, gets cleared too fast by the liver, or shows early toxicity signals. Screening for ADMET properties early, before committing synthesis and assay budget, is one of the highest-leverage steps in a drug discovery workflow.
How ChemOrchestra's ADMET tool works
The ADMET node takes a SMILES string as input — no structure file, no local software, no command line. Drop it into a workflow, connect it to the ADMET Prediction tool, and run it directly in the browser. The tool returns a panel of predicted properties covering the standard ADMET categories, which you can inspect directly or export for downstream filtering across a candidate list.
Reading the results
Each ADMET property in the output panel is a predicted value, not a measured one — treat it as a triage signal for prioritizing which candidates are worth carrying forward, not as a final answer on developability. A molecule that fails multiple ADMET flags at once is a strong candidate to deprioritize; a molecule that passes is a candidate worth validating further, not one that's already cleared for development.
When to run ADMET vs. wait for wet-lab assays
Run ADMET prediction as early as possible — ideally right after a candidate is generated or optimized, before any synthesis work begins. It's a filter for narrowing a large list down to the molecules worth the cost of a real assay, not a replacement for one. Pair it with docking or co-folding results from the same workflow to prioritize candidates on both binding and developability before anything goes to the bench.
