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