Allgemeine Beschreibung

Methoctramine (N, N′-bis [6-[[(2-methoxyphenyl)-methyl] hexyl]-1, 8-octane] diamine) is a derivative of polymethylene tetramine.

Anwendung

Methoctramine hydrate has been used:
  • As a muscarinic receptor 2 antogonist.
  • As a test molecule to check its effect on premature osteogenic differentiation of HGPS (Hutchinson-Gilford progeria syndrome) iPS (induced pluripotent)-derived mesenchymal stem cells.

Biochem./physiol. Wirkung

Methoctramine is a selective M2 muscarinic receptor antagonist at nM concentrations. At mM concentrations, methoctramine directly inhibits the high affinity GTPase activity of G proteins. The increase in calcium and arachidonic acid release were attenuated by the M2 receptor antagonist methoctramine, but not by the M3 receptor antagonist p-fluoro-hexahydro siladifenidol.
Methoctramine is a selective M2 muscarinic receptor antagonist at nM concentrations. At mM concentrations, methoctramine directly inhibits the high affinity GTPase activity of G proteins. In oesophageal muscle, acetylcholine-mediated increase in calcium and arachidonic acid release were reduced by the M2 receptor antagonist, methoctramine. Methoctramine infused bilaterally in the dorsolateral striatum, considerably enhanced memory in cognitively impaired aged rats. Methoctramine plays a vital role in muscarinic receptor classification.

We have previously shown that acetylcholine-induced contraction of oesophageal circular muscle depends on activation of phosphatidylcholine selective phospholipase C and D, which result in formation of diacylglycerol, and of phospholipase 2 which produces arachidonic acid. Diacylglycerol and arachidonic acid interact
