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.

Two-photon (2P) excitation is a cornerstone approach widely employed in neuroscience microscopy for deep optical access and sub-micrometric-resolution light targeting into the brain. However, besides structural and functional imaging, 2P optogenetic stimulations are less routinary, especially in 3D. This is

We examined whether skeletal muscle overexpression of PGC-1α1 or PGC-1α4 affected myokine secretion and neuromuscular junction (NMJ) formation. A microfluidic device was used to model endocrine signaling and NMJ formation between primary mouse myoblast-derived myotubes and embryonic stem cell-derived motor

The binding of d-tubocurarine and several of its analogs to the mouse nicotinic acetylcholine receptor (AChR) was measured by competition against the initial rate 125I-alpha-bungarotoxin binding to BC3H-1 cells. The changes in affinity due to methylation or halogenation at various

The issue of whether d-tubocurarine, the classical acetylcholine receptor inhibitor, inhibits the receptor by a competitive or noncompetitive mechanism has long been controversial. d-Tubocurarine, in this study, has been found to be both a competitive (KC = 120 nM) and
