A61K 38/48

acting on peptide bonds (3.4)

Introduced: January 1995

Full Title

Full titles differ between systems:

IPC:

Medicinal preparations containing peptides > Peptides having more than 20 amino acids; Gastrins; Somatostatins; Melanotropins; Derivatives thereof > Enzymes; Proenzymes; Derivatives thereof > Hydrolases (3) > acting on peptide bonds (3.4)

CPC:

Medicinal preparations containing peptides (peptides containing beta-lactam rings A61K31/00; cyclic dipeptides not having in their molecule any other peptide link than those which form their ring, e.g. piperazine-2,5-diones, A61K31/00; ergot alkaloids of the cyclic peptide type A61K31/48; containing macromolecular compounds having statistically distributed amino acid units A61K31/74; medicinal preparations containing antigens or antibodies A61K39/00; medicinal preparations characterised by the non-active ingredients, e.g. peptides as drug carriers, A61K47/00) > Peptides having more than 20 amino acids; Gastrins; Somatostatins; Melanotropins; Derivatives thereof > Enzymes; Proenzymes; Derivatives thereof > Hydrolases (3) > acting on peptide bonds (3.4)

CPC subdivides this area 7x more granularly than IPC with 6 additional codes.

6 codes are CPC-only extensions.

IPC defines codes here since 1995.
