[{"from": "human", "value": "Create a molecule that satisfies the conditions outlined in the description. The molecule is a bridged organic heteropentacyclic compund that is 3,4,5,6-tetrahydro-2H,8H-2,6-epoxyoxocino[3,2-b]xanthen-8-one substituted by hydroxy groups at positions 4 and 7, a methoxy group at position 9 and a methyl group at position 2 (the 2S,4R,6S stereoisomer). It is isolated from the marine derived fungus Chaetomium and has antiprotozoal activity. It has a role as a metabolite and an antiprotozoal drug. It is a member of phenols, an organic heteropentacyclic compound, a cyclic ketone, a bridged compound and a cyclic ketal."}, {"from": "gpt", "value": "[C][C@][C][C@@H1][Branch2][Ring2][O][C][C@H1][Branch1][Ring2][O][Ring1][=Branch1][C][=C][Branch1][Ring2][O][Ring1][=Branch2][C][=C][C][=Branch1][Branch1][=C][Ring1][#Branch1][O][C][=Branch1][C][=O][C][=C][Branch1][Ring2][O][Ring1][=Branch2][C][=C][C][=C][Ring1][#Branch1][O][C][O]"}]
