[C][C][C][C][N][C][C][C][C][C][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 a long-acting, amide-type local anesthetic. Bupivicaine reversibly binds to specific sodium ion channels in the neuronal membrane, resulting in a decrease in the voltage-dependent membrane permeability to sodium ions and membrane stabilization; inhibition of depolarization and nerve impulse conduction; and a reversible loss of sensation."}]
