2-Piperidinecarboxamide, 1-butyl-N-(2,6-dimethylphenyl)-, (2R,3R)-2,3-dihydroxybutanedioate (2:1)

Bupivacaine is a BK/SK, Kv1, Kv3, TASK-2 K Channel and voltage-gated Na channel blocker used as an anesthetic. It maybe neurotoxic at high does, inducing apoptosis in neuroblastoma cells. It acts by binding to the intracellular portion of voltage-gated sodium channels and blocking sodium influx into nerve cells.
