(+)-TUBOCURARINE CHLORIDE PENTAHYDRATE

[Description]:

D-Tubocurarine chloride pentahydrate is the chloride salt form of Tubocurarine, a nicotinic acetylcholine receptors (AChR) antagonist, and can be used as a skeletal muscle relaxant during surgery or mechanical ventilation. D-Tubocurarine chloride pentahydrate is also a potent neuromuscular blocking agent[1][2][3].

[In Vitro]

Treatment of Caco-2 cells with the AChR antagonist Tubocurarine (10 µM) induces a disorganization of adherents junctions. Buffalo milk-derived products (MBCP) (18 µM) attenuates Tubocurarine AChR antagonist effects on Caco-2 cells adherens junctions[1].

Acetylcholine induces Ca2+ signaling in chicken retinal pigmented epithelial cells during dedifferentiation.

Am. J. Physiol. Cell Physiol. 296 , C1195-206, (2009)

Retinal pigmented epithelial cells exchange their cellular phenotypes into lens cells and neurons, via depigmented and non-epithelial-shaped dedifferentiated intermediates. Because these dedifferentia...

J. Biol. Chem. 272 , 24891-24898, (1997)

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 BC...

Acetylcholine receptor inhibition by d-tubocurarine involves both a competitive and a noncompetitive binding site as determined by stopped-flow measurements of receptor-controlled ion flux in membrane vesicles.

Biochemistry 25 , 1786, (1986)

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 ...
