KEGG DGROUP contains structurally and functionally related groups of D number entries in KEGG DRUG. There are five types of drug groups.
Chemical - grouped as identical chemical structures with minor variations of salts, hydration states, etc.
Structure - grouped as similar chemical structures having the same skeleton, etc.
Target - grouped by drug targets
Class - drug classes often representing similar mechanisms of action
Metabolism - grouped by substrates, inhibitors and inducers of drug metabolizing enzymes and transporters
Chemical groups are often used for identifying essentially the same active ingredients of drugs in different countries.
