Task: Please create a text description for a molecule.
Molecule SMILES: Oc1cc(O)c2c(c1)O[C@H](c1ccc(O)c(O)c1)[C@@H](O)[C@@H]2c1c(O)cc(O)c2c1O[C@H](c1ccc(O)c(O)c1)[C@H](O)C2
Constraint: Answer the question with complete sentences.
Result: The molecule is a proanthocyanidin obtained by the condensation of (-)-epicatechin and (+)-catechin units. It has a role as an antioxidant, an EC 5.99.1.3 [DNA topoisomerase (ATP-hydrolysing)] inhibitor and an antineoplastic agent. It is a proanthocyanidin and a hydroxyflavan. It derives from a (-)-epicatechin and a (+)-catechin.
