Application

Gallamine triethiodide has been used:
  • as a relaxant for measuring spinal trigeminal nucleus recordings from single neurons.
  • as an antagonist in neuroblastoma cells as M2 receptor
  • to reduce eye movement during retinal surgery in rat

Biochem/physiol Actions

Gallamine triethiodide has anti-muscarinic effect. It is a competitive antagonist for the muscarinic receptor. Gallamine is regarded as neuromuscular blocking agent.
Muscle relaxant; allosteric muscarinic receptor antagonist with an order of potency of M2 > M1 = M4 > M3 = M5. Ligand for the peripheral anionic binding site of acetylcholinesterase.

Comparison of the effect of three 'peripheral' site ligands, propidium, d-tubocurarine, and gallamine, on acetylcholinesterase (acetylcholine hydrolase; EC 3.1.1.7) of Torpedo and chicken shows that all three are substantially more effective inhibitors of the Torpedo enzyme than of the chicken

The M(2) muscarinic receptor has two topographically distinct sites: the orthosteric site and an allosteric site recognized by compounds such as gallamine. It also can exhibit cooperative effects in the binding of orthosteric ligands, presumably to the orthosteric sites within

Bitopic binding properties apply to a variety of muscarinic compounds that span and simultaneously bind to both the orthosteric and allosteric receptor sites. We provide evidence that fluorescent pirenzepine derivatives, with the M1 antagonist fused to the boron-dipyrromethene [Bodipy (558/568)]
