Q: Please describe this drug.
 The Molecule can be represented with the SMILES O[C@H]([C@H](O)[C@@H]1CO1)[C@H]1CO1.
Answer: Dianhydrogalactitol is a bifunctional hexitol derivative with potential antineoplastic activity. Dianhydrogalactitol alkylates and cross-links DNA via an epoxide group during all phases of the cell cycle, resulting in disruption of DNA function and cell cycle arrest. (NCI04)
