Question: How many hydrogen bond acceptors are there in this compound, calculated according to Lipinski's original rules (i.e., counting N and O atoms)?
Constraint: The Molecule can be represented with the SMILES Nc1nc(=O)c2c([nH]1)NC[C@H](CNc1ccc(C(=O)N[C@@H](CCC(=O)[O-])C(=O)[O-])cc1)N2C=O.[Ca+2].
Result: 14
