[{"from": "human", "value": "Generate a molecule based on the given description. The molecule is a C-glycosyl compound that is 1,8-dihydroxy-3-methylanthracen-9(10H)-one substituted by a 2-O-senecioyl-alpha-lyxopyranosyl moiety at position 10 via a C-glycosidic linkage (the 10R stereoisomer). It is isolated from the leaves of Alvaradoa haitiensis and exhibits cytotoxicity against human oral epidermoid carcinoma. It has a role as a metabolite and an antineoplastic agent. It is a C-glycosyl compound, a member of anthracenes and a polyphenol. It is functionally related to a 3-methylbut-2-enoic acid."}, {"from": "gpt", "value": "[C][C][=C][C][=C][Branch1][Branch2][C][=Branch1][Ring2][=C][Ring1][=Branch1][O][C][=Branch1][C][=O][C][=C][Branch2][Ring2][Ring2][C@H1][Ring1][#Branch2][C@H1][C@@H1][Branch2][Ring1][O][C@H1][Branch2][Ring1][=Branch1][C@H1][Branch1][Branch2][C@@H1][Branch1][Ring2][O][Ring1][=Branch1][O][O][C][=Branch1][C][=O][C][=C][Branch1][C][C][C][O][O][C][=C][C][=C][Ring2][Ring1][#Branch1][O]"}]
