[C][N][C@@][Branch1][=Branch2][C][C][C][C][C][Ring1][=Branch1][=O][C][=C][C][=C][C][=C][Ring1][=Branch1][Cl]"}, {"from": "gpt", "value": "The molecule is a cyclohexanone derivative and S-enantiomer of racemic ketamine, with analgesic, anesthetic and antidepressant activities. Although the mechanism of action is not fully understood, upon administration, esketamine targets, non-competitively binds to, and blocks N-methyl D-aspartate (NMDA) receptors. This reduces pain perception, induces sedation, and produce dissociative anesthesia."}]
