A61K - Cooperative Patent Classification

CPC - A61K - 2013.07 - page 70
-
the carrier being an organic macromolecular compound, i.e. an
oligomeric, polymeric, dendrimeric molecule (not being a peptide,
protein, polyamino acid (see A61K 49/00 or A61K 14/00 ) or an
antibody (see A61K 49/00 or A61K 16/00 )
A61K 49/122 . . . . . { dimers of complexes or complex-forming compounds }
A61K 49/124 . . . . . { dendrimers, dendrons, hyperbranched compounds }
NOTE
-
Said compounds are either complexes or complex-forming
compounds, or they form a backbone to which MRI active nuclei are
complexed or covalently linked through chelating groups. In that
latter case, the subgroup A61K 49/085 being also given.
Dendrimeric, dendronised or hyperbranched polyamino acids used
as carriers are also classified in A61K 49/146
A61K 49/126 . . . . . { Linear polymers, e.g. dextran, inulin, PEG }
A61K 49/128 . . . . . . { comprising multiple complex or complex-forming groups, being either
part of the linear polymeric backbone or being pending groups
covalently linked to the linear polymeric backbone }
A61K 49/14 . . . . Peptides, e.g. proteins
NOTE
-
In that latter case, classification is also made in A61K 49/085
NOTE
-
the carrier being a peptide (polyamino acid, A61K 49/14 T) or protein
(not an antibody, see A61K 49/16 ). If the MRI-active nucleus being
linked to the peptide or protein or polyamino acid via a complexing or
chelating group, the subgroup A61K 49/085 should also be given. If the
peptide or protein or polyamino acid being a dendrimer, a dendron, or
hyperbranched, then the A61K 49/124 being also given
A61K 49/143 . . . . . { the protein being an albumin, e.g. HSA, BSA, ovalbumin }
A61K 49/146 . . . . . { the peptide being a polyamino acid, e.g. poly-lysine }
A61K 49/16 . . . . . Antibodies ; Immunoglobulins ; Fragments thereof
NOTE
-
the protein being an antibody, an immunoglobulin or a fragment
thereof. If the MRI-active nucleus being linked to the antibody via a
complexing or chelating group, the subgroup A61K 49/085 should
also be given
A61K 49/18 . . characterised by a special physical form, e.g. emulsions, microcapsules, liposomes
NOTE
-
Classification being also made according to the molecule complexing or
