ProvBench — EGFR Bioactivity is a curated catalog of 28,689 original IC50/Ki bioactivity measurements for the EGFR protein (UniProt P00533, ChEMBL CHEMBL203). It was created by Ni3SinghR to demonstrate rigorous data provenance, metadata cataloging, and multi-source harmonization, and was last updated on 2026-06-29. The dataset contains 15,507 unique compounds and 11,107 compound/target consensus values.
Use Cases
- Train quantitative structure-activity relationship (QSAR) models based on the 11,107 compound/target consensus values.
- Benchmark data provenance and harmonization methods based on the multi-source, link-tracked measurement data.
- Analyze compound bioactivity distributions for the EGFR target based on the 28,689 original measurements.
- Validate computational drug discovery pipelines using the standardized, curated compound catalog.
Strengths
- 28,689 original bioactivity measurements with preserved provenance.
- 15,507 unique compounds standardized on InChIKey.
- 11,107 compound/target consensus values derived from multi-source harmonization.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified as the last update timestamp is 2026-06-29.
Provenance
- Source
- Multi-source via ChEMBL, including BindingDB Patent Bioactivity.
- Collection Method
