“Both” means ChEMBL and the Guide to Pharmacology each record this medicine acting on this protein; “only” means one source records it and the other does not (often because it lists fewer secondary targets). The Guide to Pharmacology adds a medicine here only when this protein is its primary target. Medicines without a link have no page on this site yet.

From ChEMBL's drug-disease records, which draw on trial registries. A trial phase is not an approval; approved uses are on each medicine's page from the regulators' own records.
Which medicines act on this protein comes from two independent, expert-curated sources: ChEMBL's mechanism-of-action records (via the Open Targets Platform) and the IUPHAR/BPS Guide to PHARMACOLOGY. Each row says which of them lists it. Data from them is shared here under their share-alike licences (CC BY-SA 3.0 and 4.0).
A job re-reads both sources every 30 days. Medicines are matched to our pages by exact name or a ChEMBL-curated synonym, and to the Guide to Pharmacology by ChEMBL ID or exact name, never by a close spelling. 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.
