[C][C][C][N][C][C][C][C][C@H1][Ring1][=Branch1][C][=Branch1][C][=O][N][C][=C][Branch1][Branch2][C][=C][C][=C][Ring1][=Branch1][C][C].[Cl]"}, {"from": "gpt", "value": "The molecule is the hydrochloride salt of ropivacaine, a local anesthetic of the amide type with analgesic activity. Ropivacaine binds to voltage-gated sodium ion channels in the neuronal membrane, thereby preventing the permeability of sodium ions and resulting in a stabilization of the neuronal membrane and inhibition of depolarization; nerve impulse generation and propagation are blocked, resulting in a reversible loss of sensation."}]
