[{"from": "human", "value": "Create a molecule that satisfies the conditions outlined in the description. The molecule is an amide-type local anesthetic agent.  At the injection site, mepivacaine binds to specific voltage-gated sodium ion channels in neuronal cell membranes, which inhibits both sodium influx and membrane depolarization. This leads to a blockage of nerve impulse initiation and conduction and results in a reversible loss of sensation. Compared to other local anesthetics, this agent has a more rapid onset and moderate duration of action."}, {"from": "gpt", "value": "[C][C][=C][Branch1][#Branch2][C][=Branch1][=Branch1][=C][C][=C][Ring1][=Branch1][C][N][C][=Branch1][C][=O][C][C][C][C][C][N][Ring1][=Branch1][C]"}]
