[{"from": "human", "value": "Could you give me a brief overview of this molecule? [C][N][C][Branch1][=Branch2][C][C][C][C][C][Ring1][=Branch1][=O][C][=C][C][=C][C][=C][Ring1][=Branch1][Cl].[Cl]"}, {"from": "gpt", "value": "The molecule is the hydrochloride salt of a synthetic derivative of cyclohexanone with analgesic and anesthetic activities. Although its mechanism of action is not well understood, ketamine appears to non-competitively block N-methyl-D-aspartate (NMDA) receptors and may interact with opioid mu receptors and sigma receptors, thereby reducing pain perception, inducing sedation, and producing dissociative anesthesia."}]
