| Notes |
|
| (1) | This subclass covers compounds containing a cyclopenta[a]hydrophenanthrene skeleton or a ring structure derived therefrom: |
|
| – | by contraction or expansion of one ring by one or two atoms, |
|
| – | by contraction or expansion of two rings each by one atom, |
|
| – | by contraction of one ring by one atom and expansion of one ring by one atom, |
|
| – | by substitution of one or two carbon atoms of the cyclopenta[a]hydrophenanthrene skeleton, which are not shared by rings, by hetero atoms, in combination with the above defined contraction or expansion or not, or |
|
| – | by condensation with carbocyclic or heterocyclic rings in combination with one or more of the foregoing alterations or not. [4] |
|
| (2) | Therapeutic activity of compounds is further classified in subclass A61P. [7] |
|
| (3) | In this subclass, it is desirable to add the indexing codes of subclass C07M. The indexing codes should be unlinked. [6] |
