Allopurinol kegg identifier?

What is the KEGG identifier for allopurinol?

KEGG’s compound page for allopurinol lists its KEGG compound ID as C00551.

How can I find it in KEGG (so I get the right entry)?

In KEGG Compound (linkable at https://www.genome.jp/dbget-bin/www_bget?cpd:C00551), searching for “allopurinol” should return the same compound entry, with the compound code cpd:C00551.

Is this different from KEGG Drug, pathways, or target IDs?

KEGG uses different identifier types:
- KEGG Compound IDs use the format cpd:C00551 for small molecules like allopurinol.
- KEGG Drug and KEGG Disease/Pathway entries use other ID schemes, so you’ll want to make sure you’re looking at the compound record when you need the “allopurinol KEGG identifier.”
