From the structure of penicillin above, would you expect it to be acidic, neutral or basic? Explain your answer as fully as you can.

I think it would be acidic because of the -COOH. The -NH- can be basic, but it is attached to =C=O which is deactivating. the electron density on the N atom is reduced and the tendency to accept a proton decreases.
The other Nitrogen atom is also bonded to a deactivating =C=O.
Is this reasoning ok?
