SMILES: C1=CC(=CC=C1C2=CC(=O)C3=C(O2)C(=C(C=C3O)O)C4=C(C=CC(=C4)C5=CC(=O)C6=C(C=C(C=C6O5)O)O)O)O
Description: The molecule is a biflavonoid that is obtained by oxidative coupling of two molecules of apigenin resulting in a bond between positions C-3 of the hydroxyphenyl ring and C-8 of the chromene ring. A natural product found particularly in Ginkgo biloba and Hypericum perforatum. It has a role as a cathepsin B inhibitor, an antiviral agent, an angiogenesis inhibitor, a P450 inhibitor and a plant metabolite. It is a biflavonoid, a hydroxyflavone and a ring assembly.
