A61K - Cooperative Patent Classification

CPC - A61K - 2013.07 - page 57
peptidic linker are classified in A61K 47/48338 )
NOTE
-
The connection of the drug to the peptide, protein or polyamino acid can
be by a direct covalent linkage or through a linker Fusion/chimeric proteins
genetically produced, e.g. by recombinant DNA technology, are classified
in C07K 2319/00 and subgroups, not in A61K 47/48246 and subgroups.
A61K 47/48246 and its subgroups only cover the conjugates wherein a
peptide or protein being the pharmacologically or therapeutically active
agent has been linked to another peptide or protein being the modifying
agent via chemical methods. In that latter example of a
chemically-produced peptide or protein-peptide or protein conjugate, what
being classified in A61K 47/48246 or in one of its subgroups being the
peptide or protein used as modifying agent
A61K 47/48253 . . . . { the peptide, protein or polyamino acid in the drug conjugate being a
branched, dendritic or hypercomb peptide }
A61K 47/48261 . . . . { the peptide or protein in the drug conjugate being a toxin or a lectin, e.g.
clostridial toxins or Pseudomonas exotoxin }
A61K 47/48269 . . . . { the peptide or protein in the drug conjugate being a cytokine, e.g. IL2,
chemokine, growth factors, interferons being the inactive part of the
conjugate }
NOTE
-
ligands of growth factors are not classified here
A61K 47/48276 . . . . { the peptide or protein in the drug conjugate being a receptor as such, e.g.
CD4; a cell surface antigen ( therefore not a peptide ligand targeting the
antigen ) ; a cell surface determinant, i.e. a part of the surface of a cell }
NOTE
-
a peptide targeting a receptor being not classified here
A61K 47/48284 . . . . { the peptide or protein in the drug conjugate being an albumin, e.g. HSA,
BSA, ovalbumin, or a Keyhole Limpet Hemocyanin (KHL) }
A61K 47/48292 . . . . { the peptide or protein in the drug conjugate being a connective tissue
peptide, e.g. collagen, fibronectin, gelatin }
A61K 47/483 . . . . { the peptide or protein in the drug conjugate being a transferrin, e.g. a
lactoferrin or ovotransferrin }
A61K 47/48307 . . . . { the peptide or protein in the drug conjugate being a haemoglobin }
A61K 47/48315 . . . . { the peptide or protein in the drug conjugate being a polycationic or
polyanionic oligopeptide, polypeptide or polyamino acid, e.g. polylysine,
polyarginine, polyglutamic acid, peptide TAT }
A61K 47/48323 . . . . . { polyanionic oligopeptide, polypeptide or polyamino acid, used to
complex nucleic acids being the therapeutic agent }
A61K 47/4833 . . . . { the entire peptide or protein drug conjugate elicits an immune response,
e.g. conjugate vaccines }
NOTE
-
Haptens, e.g. conjugate of morphine or nicotine and KLH inducing an
immune response being classified in A61K 47/4833 and A61K
