Task: Please give me a molecule SMILES based on the text description.
Description: The molecule is a 4-hydroxy monocarboxylic acid anion resulting from the removal of a proton from the carboxy group of 4-hydroxybutyric acid. It has a role as an anaesthesia adjuvant and an intravenous anaesthetic. It is a short-chain fatty acid anion, a hydroxy fatty acid anion and a 4-hydroxy monocarboxylic acid anion. It derives from a butyrate. It is a conjugate acid of a 4-hydroxybutyric acid.
Result: O=C([O-])CCCO
