[{"from": "human", "value": "Based on the given information, design a molecule that meets the desired specifications. The molecule is an enyne that is (4E,15Z,28E)-dotriaconta-4,15,28-triene-1,31-diyne substituted by hydroxy groups at positions 3 and 30 (the 3R,30R-stereoiosmer). It has been isolated from the marine sponge Petrosia. It has a role as an antineoplastic agent, an animal metabolite and a marine metabolite. It is a diol, an enyne, a secondary alcohol and a terminal acetylenic compound."}, {"from": "gpt", "value": "[C][#C][C@@H1][Branch2][Ring1][P][/C][=C][/C][C][C][C][C][C][C][C][C][C][C][/C][=C][\\C][C][C][C][C][C][C][C][C][/C][=C][/C@H1][Branch1][Ring1][C][#C][O][O]"}]
