Task: Please create a text description for a molecule.
Molecule SMILES: CC(=O)OC[C@]12Oc3ccc(-c4ccc5c(c4O)C(O)=C4C(=O)C[C@@H](C)[C@@H](OC(C)=O)[C@@]4(CO)O5)c(O)c3C(O)=C1C(=O)C[C@@H](C)[C@H]2OC(C)=O
Constraint: Answer the question with full sentences.
Result: The molecule is a biaryl that is 5,5',7,7',9,9',10a,10a'-octahydro-6H,6'H-2,2'-bixanthene substituted by acetyloxy groups at C-5 and C-5', (acetyloxy)methyl group at C-10a, hydroxy groups at C-1, C-1', C-8 and C-8', hydroxymethyl group at C-10a', methyl groups at C-6 and C-6' and oxo groups at C-9 and C-9' respectively. A dimeric tetrahydroxanthone derivative isolated from Phomopsis longicolla, it exhibits antibacterial and cytotoxic activities. It has a role as a metabolite, an antimicrobial agent and an antineoplastic agent. It is an acetate ester, a biaryl, a polyphenol, a primary alcohol and a member of xanthones.
