Task: Please answer the following question about the molecule with SMILES C[C@H]1c2cccc(O)c2C([O-])=C2C(=O)[C@]3([O-])C([O-])=C(C(N)=O)C(=O)[C@@H](N(C)C)[C@@H]3[C@@H]([O-])[C@@H]21.[Ca+2].[Ca+2].
Question: Please describe this drug.
Completion: Doxycycline Calcium is the calcium salt form of doxycycline exhibiting antimicrobial activity.  Doxycycline blocks binding of aminoacyl-tRNA to the mRNA-ribosome complex, thereby inhibiting protein synthesis.  In addition, this agent has exhibited inhibition of collagenase activity. (NCI)
