Methodology
ChEMBL is the molecule and bioactivity backbone; PubChem supplies compound identifiers and structures. FDA Drugs@FDA, Orange Book, and RxNorm should be used to validate approval status and clinical naming for expanded releases.
Sources
ChEMBL
Manually curated bioactive and drug-like molecule data, including drug status and ChEMBL identifiers.
PubChem
Canonical compound identifiers, names, formulas, structures, SMILES, and downloadable compound records.
FDA Drugs@FDA
Official FDA application, product, ingredient, and marketing-status data for approved drug products.
FDA Orange Book
Approved drug products, active ingredients, application numbers, RLD/RS flags, and therapeutic equivalence context.
RxNorm
Normalized clinical drug names and prescribable medication vocabulary.
RDKit
Derived descriptors such as molecular weight, LogP, TPSA, hydrogen-bond counts, and canonicalized structures.
