NOTE
-
This subclass covers compounds containing saccharide radicals. (see the definitions in Note 3. below).

This subclass does not cover polysaccharides which for the purpose of this subclass are defined as having more than five saccharide radicals attached to each other by glycosidic linkages.

In this subclass, the following expressions are used with the meaning indicated:
- "saccharide radical" which is derived from acyclic polyhydroxy-aldehydes or acyclic polyhydroxy-ketones, or from their cyclic tautomers, by removing hydrogen atoms or by replacing hetero bonds to oxygen by the same number of hetero bonds to halogen, nitrogen, sulfur, selenium, or tellurium, in accordance with either of the following definitions:
It consists of an uninterrupted carbon skeleton and oxygen atoms directly attached thereto, and;

is considered to be terminated by every bond to a carbon atom of a cyclic structure and by every bond to a carbon atom having three bonds to hetero atoms, e.g. ester or nitrile radicals, and;

contains within the carbon skeleton an unbranched sequence of at the most six carbon atoms in which at least three carbon atoms at least two in the case of a skeleton having only four carbon atoms have one single bond to an oxygen atom as the only hetero bond
{
but at least three for compounds in which at least one carbon to oxygen bond involved in a) or b) has been replaced by a carbon bond to a hetero atom other than oxygen
}
, and
in a cyclic or acyclic sequence, at least one other carbon atom
{
that is not doubly bound to a carbon atom, e.g. glycals
}
has two single bonds to oxygen atoms as the only hetero bonds, or

in an acyclic sequence, at least one other carbon atom
{
that is not doubly bound to a carbon atom
}
has one double bond to an oxygen atom as the only hetero bond;


{
has in the gamma or delta position in respect to the carbon atom bearing those two single bonds or this double bond to oxygen a carbon atom bearing one single bond to oxygen
}

{
It is also a radical derived from a radical as defined in a. above by replacing at the most four of the specified hetero bonds to oxygen by the same number of hetero bonds to halogen, nitrogen, sulfur, selenium, or tellurium;
}
- "heterocyclic radical" or "hetero ring" is considered to exclude saccharide radicals as defined above


Attention is drawn to the notes following the tile of class C07 .

The conditions 3) a) or 4) have not to be fulfilled in respect to C07H19/00E1

Where a compound may exist --- to be written in Kekulè form

For the purpose of this subclass, the following definitions apply:
A "hetero ring" is a ring having at least one halogen, nitrogen, oxygen, sulfur selenium or tellurium atom as a ring member;

Two rings are "condensed" if they share at least one ring member, i.e. "spiro" and "bridged" are considered as condensed. The term "bridged" denotes the presence of at least one fusion other than ortho, peri and spiro;

A "condensed ring system" is a ring system in which all rings are condensed among themselves;

The "number of relevant rings" in a condensed ring system equals the number of scissions necessary to convert the ring system into one acyclic chain;

The "relevant rings" in a condensed system are chosen according to the following criteria consecutively:
Lowest number of ring members

Highest number of hetero atoms as ring members

Lowest number of members shared with other rings

Last place in the classification scheme



In the absence of specific places, hydrogenated or condensed hetero rings are classified with the parent ring

In the absence of an indication to the contrary, a compound is classified in the last appropriate place

Groups C07H 3/04 and C07H 3/06 take precedence over C07H 3/08 to C07H15/18D -with the exception of C07H 13/06 , C07H13/12U, C07H15/00F, C07H 15/06 , C07H 15/08 , C07H15/10D2 , C07H 15/16 - and over C07H 15/20 as far as a phenyl radical is involved; the purpose of this inversion of the last place rule is to avoid multiple classification for documents describing compounds, having a complement inhibiting activity or belonging to the "blood-group substances" occuring in tissue fluids, in secretions and at cell and tissue surfaces (e.g. antigen determinants) or forming part of cell membranes. Documents in which both disaccharides and oligosaccarides of this kind are described are only classified in C07H 3/06 .

Group C07H 9/00 takes precedence over C07H 11/00 to C07H 15/00 when at least one ring heteroatom is different from oxygen, however anhydro derivatives of nucleosides and nucleotides C07H 19/00 .

Group C07H 15/252 takes precedence over C07H 17/00 when the naphtacene ring is further condensed to a heteroring, and over C07H 15/26 when the carbocyclic ring is substituted by a hetero ring]
