2. The three DARCP sources with conceptually equivalent curated links ( 3. As a commendable initiative the Journal of Medicinal Chemistry requires authors to provide SMILES and some cases, they may also add activity values, as supplementary data. These are made available as comma-separated (.csv) files. However, while this was envisaged to facilitate automated extraction, no one actually does this (or at least has not openly surfaced the results). These files thus useful contain C-R but A and P remain in the paper (although DARCP from this journal is extensively curated by GtoPdb, ChEMBL and BindingDB).
