Your Molecule Is Potent. Will It Ever Reach the Target?

ADME Hero is an AI platform that predicts 34 absorption, distribution, metabolism and excretion endpoints for any molecule you can draw. It was built for missions where a pharmacokinetic study is impossible: no clinic, no blood draws, no resupply. That constraint is now an advantage for discovery teams on Earth.

Nezu Biotech is  part of the European Space Agency Business Incubation Centre (ESA-BIC).

Accurate Results

ADME Hero models are trained on curated experimental data and validated against the assays they replicate. Performance is reported endpoint by endpoint. You can see exactly how much weight each prediction deserves.

Comprehensive Coverage

Thirty-four endpoints across four families: 15 absorption, 4 distribution, 12 metabolism and 3 excretion. All assessed together, for every molecule you send.

Efficient Analysis

We process thousands of structures at a time. Work that would occupy several assay queues for months comes back as a finished report, while the chemistry is still open to change.

Cost Efficiency

In silico ADME costs a fraction of the assay panel it prioritises, which makes it viable at the only stage where it changes everything: before synthesis. Wet-chemistry budget then goes to the compounds that earned it.

Clear Reporting, No Learning Curve

You receive a visual report your whole team can read and a detailed table your DMPK scientists can interrogate. No software to install, no dashboard to learn, no data-science hire required.

Context, Not Just Numbers

Every prediction is positioned against approved drugs, and against those approved for the same indication as yours. Instead of debating whether a clearance value is acceptable, you can see where your candidate sits among drugs that reached the market.

Bring us a handful of molecules and a question you can't currently answer: "why my drug was not absorbed?", "will it reaches the brain?", "which isoform is the interaction risk."

We'll show you what an ADME Hero report would say about them.

Frequently Asked Questions

Never. Client structures are kept strictly separate from our training data and are not used to improve our models, under written confidentiality terms agreed before you send anything.

ADME Hero is a decision-support tool for the discovery stage, not a regulatory submission package. Filings such as an IND or CTA require GLP-compliant laboratory and in vivo studies under ICH M3(R2) and equivalent guidance, and no in silico method substitutes for them. ADME Hero's role sits earlier: it ensures that when you commission those studies, you commission them on the molecules most likely to pass.

No, and we wouldn't claim it. It decides which compounds are worth putting into them. Screening a series in silico and sending only the survivors to the bench is where the saving comes from — not from skipping the bench.

No. You send structures; we return a report written for medicinal chemists, DMPK scientists and project leads. All modelling happens on our side, and a specialist walks you through your first report.

Chemical structures (SMILES or SDF), and if you want indication-matched benchmarking, the therapeutic area you're working in. Nothing about your assays, your formulations or your programme is required.

Performance is reported per endpoint, not as one headline figure, because endpoints differ in how well they're modelled. Across our panel, agreement with the corresponding laboratory assays runs at 70% - 95%. 

The panel is built around human-relevant endpoints wherever human data exists: human intestinal absorption, oral bioavailability, plasma protein binding, human microsomal and hepatocyte clearance, and the human CYP isoforms. Where an endpoint refers to a model system — Caco-2, MDCK, PAMPA — the report says so explicitly, because that is how the reference assay is defined.

Performance is reported per endpoint rather than as one headline number, because a solubility regression and a P-gp classification are not measured the same way. Continuous endpoints are reported with correlation and mean absolute error against held-out experimental data; classifications with agreement rates. Across the panel, classification agreement runs at 70%–95%.

Predictions are strongest inside the chemical space the models were trained on. For unusual structures, confidence drops — and we flag when a molecule falls outside that space rather than reporting a number as if it were certain. Those compounds are the right candidates for early experimental confirmation.

It gives you the two predictions that decide it together: blood–brain barrier permeability and P-glycoprotein substrate status. A compound that crosses but is actively pumped back out is a common and expensive surprise in CNS programmes, and it is visible on a screen.

Yes. Skin penetration rate, solubility, lipophilicity and pKa are directly useful for cosmetic, topical and agrochemical development, and the metabolism panel matters wherever a compound will meet a liver.

They are complementary. ADME Hero predicts where a molecule goes; ToxSpotter predicts what harm it may cause. Together they give a full ADMET profile in a single submission, and most clients eventually run both.

Processing is fast; the schedule is set by scope and agreed upfront. Most engagements deliver in days rather than the months an equivalent assay campaign would take. A specialist then walks you through the report, and you keep both the visual document and the full data table.
