Beschreibung

Application

(+)-Tubocurarine chloride pentahydrate has been used:

• as an acetylcholine receptor antagonist in synapse blocking experiment to study its effect on neuromuscular junction formation (NMJ) formation in a co-culture system of human skeletal muscles and human stem cell-derived motoneurons
• to induce paralysis in zebrafish larvae to study whole-brain imaging of seizures by two-photon light-sheet microscopy
• to block NMJ to study its role in myotube contraction

Biochem/physiol Actions

(+)-Tubocurarine chloride pentahydrate serves as a neuromuscular blocker.

Classical competitive antagonist of the nicotinic acetylcholine receptor. Structure-activity relationships and conformational studies for tubocurarine binding at the nicotinic AChR.
