In your code you do the following:
m=MurckoScaffold.GetScaffoldForMol(mol)
sca=MurckoScaffold.MakeScaffoldGeneric(m)
The first call finds the Murcko scaffold and converts cyclopentanone
to cyclopentanone (i.e. no change).
The second call converts that to the generic scaffold, where all atoms
are "C" and all bonds are single.
To demonstrate, here's the output of running your script on your input
file where I've printed :
input_smiles murcko_smiles generic_murcko_smiles
Cc1ccccc1 c1ccccc1 C1CCCCC1
CC1CCCCC1 C1CCCCC1 C1CCCCC1
c1cc(=C)ccc1=C c1cc(=C)ccc1=C CC1CCC(C)CC1
O=C1C=CC(=O)C=C1 O=C1C=CC(=O)C=C1 CC1CCC(C)CC1
CC1CCCC1 C1CCCC1 C1CCCC1
O=C1CCCC1 O=C1CCCC1 CC1CCCC1
Best Regards,
-greg
