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.

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)]

Gallamine and tacrine are allosteric antagonists at muscarinic M2 acetylcholine receptors and inhibitors of acetylcholinesterase. At both acetylcholine-binding proteins, gallamine and tacrine are known to occupy two different binding sites: in M2 receptors within the allosteric binding area and in

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
