Hello,
I am not very familiar with smiles/smarts and find the following results quite
puzzling:
>>> patt =
>>> Chem.MolFromSmiles('c1ccc(cc1)C~C2NC~Cc3c2cccc3.c1ccc(cc1)C~C2NC~Cc3c2cccc3')
>>> mol =
>>> Chem.MolFromSmiles('COc1ccc2cc1Oc1ccc(cc1)CC1N(C)CCc3c1c1Oc4cc5C(C2)NCCc5cc4Oc1c(c3)OC')
>>> print mol.HasSubstructMatch(patt)
False
>>> mol =
>>> Chem.MolFromSmiles('COc1ccc7cc1Oc2ccc(cc2)CC3N(C)CCc4c3cc(c(c4)OC)Oc5ccc6c(c5)CCNC6C7')
>>> print mol.HasSubstructMatch(patt)
True
It seems that a presence of an extra Ph - O - Ph makes the difference but I am
not sure why. How should the smarts be to have positive results for both smiles
?
Thank you in advance for your help.
Best regards,
