Source assertion
ChEMBL direct single-protein activity record with source-reported and source-standardized lexical values preserved.
Lossless activity measurement
- Source-reported value
- = 9.04 uM
- Source-standardized value
- = 9.04 uM
- Reported endpoint
- Kinact
- Standardized endpoint
- Kinact
- Reported upper bound
- not reported by the source
- Reported text value
- not reported by the source
- Standardization flag
- 0
- pChEMBL from source
- not reported by the source
Reported and source-standardized fields are displayed separately and retain their exact lexical values. The standardized field does not overwrite the upstream report.
No cross-assay comparison is authorized by this record. Evaluate target, construct, endpoint, relation, units, assay format, conditions, and exact molecular form first.

Snapshot provenance
Each row is a source snapshot this record was built from: when it was retrieved, its path and SHA-256 digest, and the exact request. The snapshot files stay with the build and are not served here. These rows document this record; they are not general citations.
