laudanosine Chemical Properties,Usage,Production

Uses

Laudanosine is a metabolite of the neuromuscular-blocking drugs Atracurium (A794500) and Cisatracurium (C496700) with potentially toxic systemic effects. It crosses the blood-brain barrier and may cause excitement and seizure activity.

Definition

ChEBI: Laudanosine is a member of isoquinolines.

Purification Methods

Crystallise these from EtOH. The (±)-picrate crystallises from EtOH with m 177-178o. The (-)-isomer has m 83-85o and
