[{"from": "human", "value": "Use the given information to create a molecule that fulfills the desired purpose. The molecule is a gallate ester obtained by formal condensation of the carboxy group of gallic acid with the (3R)-hydroxy group of epicatechin. A natural product found in Parapiptadenia rigida. It has a role as a metabolite, an EC 3.2.1.1 (alpha-amylase) inhibitor and an EC 3.2.1.20 (alpha-glucosidase) inhibitor. It is a catechin, a gallate ester and a polyphenol. It is functionally related to a (-)-epicatechin and a gallic acid."}, {"from": "gpt", "value": "[C][C@H1][Branch2][Ring2][Ring2][C@H1][Branch2][Ring1][C][O][C][=C][C][=Branch1][O][=C][C][=Branch1][=Branch1][=C][Ring1][=Branch1][Ring1][#Branch2][O][O][C][=C][C][=Branch1][=Branch2][=C][Branch1][Branch1][C][=C][Ring1][=Branch1][O][O][O][C][=Branch1][C][=O][C][=C][C][=Branch1][N][=C][Branch1][Branch2][C][=Branch1][Ring2][=C][Ring1][=Branch1][O][O][O]"}]
