Use the MeSH Database to Find Your Term

If your term doesn't map, or even if it does, it's generally a good idea to search the MeSH Database to understand how your concept is represented in the vocabulary.

A couple of search options:

  1. Components of the name
    If, for example, all you have is a systematic name, try searching the MeSH Database using components of the name.
    Example: alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid
    Search: isoxazolepropionic
  2. Unique identifier
    Drugs and chemicals may also be searched in the MeSH database (or in PubMed) using their FDA Unique Ingredient Identifier (UNII), EC number from the Enzyme Nomenclature, or Chemical Abstracts Service (CAS) registry number.
    Example: Fluconazole
    Search: 8VZV102JFY

    Note: Not all records for chemicals in the MeSH database have registry number data. See more information on these numbers from the MEDLINE/PubMed Data Element Descriptions.
