Compiled from ChEMBL mechanism-of-action records via Open Targets · Last verified · Editorial standards

1,662 medicines in our registers are matched to a ChEMBL record, and 1,078 of them have a recorded mechanism of action naming the protein they act on. EGFR (epidermal growth factor receptor) is the most common single target, with 23 medicines. Each target below links to a page listing every medicine that acts on it, and each medicine links to its trials, approvals and spending. Every link is checked against a second, independent source, the IUPHAR/BPS Guide to PHARMACOLOGY: 831 of 1,361 links appear in both, and each target page says which source lists each medicine. Medicines that act on a family of proteins, such as tubulin, are shown on the medicine's own page rather than here.

A medicine is matched to ChEMBL when ChEMBL's name for it, or a synonym ChEMBL itself curates, is the same molecule as ours, and to the Guide to Pharmacology by ChEMBL ID or exact name; close spellings are never accepted. Combination products are not matched. The Guide to Pharmacology adds a medicine to a target only when that protein is its primary target.

How this page is built

Mechanisms and targets are ChEMBL's curated records as published in the Open Targets Platform, checked against the IUPHAR/BPS Guide to PHARMACOLOGY. The data on this page and in its download is shared under the same share-alike terms (CC BY-SA, and ODbL for the Guide to Pharmacology database).

A job re-reads both sources every 30 days and keeps the previous version if a refresh fails or returns far fewer medicines. No AI drafting. See our methodology. The Open Targets data on this page was last retrieved on 30 Sep 2026. How every register is built: methodology · fixes we have made: corrections log.

Please verify before you rely on this. This page is general information for life-science and pharmaceutical professionals. It is not medical advice, and it has not been reviewed by a clinician — our editorial team holds life-science qualifications, not clinical ones. It is not exhaustive and may not reflect the most recent label change. Always check the official prescribing information (US Prescribing Information or EU SmPC) and speak to your doctor or pharmacist before acting on anything here. Drugs in the same class are not automatically interchangeable, and approvals, brand names and indications differ between the US, the EU/Ireland (EMA/HPRA) and other regions. Spotted an error?
