3.5 Specific groups of biological compounds
Because of the complexity of certain new types of pharmaceutical products, such as compounds produced by biotechnology, general rules are not always easily formulated. Some of these substances may already have descriptive names assigned by other institutions such as the International Union of Biochemistry (IUB), International Union of Pure and Applied Chemistry (IUPAC), Joint Commission on Biochemical Nomenclature (JCBN). These names may not be suitable as INNs.
Annex 4 summarizes nomenclature schemes for groups of biological compounds (for details and examples please also see document WHO/PHARM S/NOM 15: The use of common steins in the selection of international nonproprietary names (INN) for pharmaceutical substances, updated regularly).
