METHYLLYCACONITINE CITRATE Chemical Properties,Usage,Production

Uses

Methyllycaconitine citrate salt has been used as an α7 nicotinic acetylcholine receptor (α7 nAChR) antagonist:

to study its effects on inflammatory response in rats post nicotine treatment
to block the activity of galantamine
to study its effects on the hepatic branch of the vagus nerve (hVNS) in rats

Biological Activity

methyllycaconitine citrate(mla) is an antagonist of α7-containing neuronal nicotinic acetylcholine receptors (nachrs; ki = 1.4 nm)[1,2].mla inhibits the decreased cell viability induced by aβ25-35, pretreatment with 5 and 10 μm. aβ25-35 treatment increases lc3-ii levels, which is inhibited by administration of methyllycaconitine citrate. mla also inhibits aβ-induced autophagosome accumulation in sh-sy5y cells[3].mla inhibits methamphetamine(meth)-induced climbing behavior by 50%. mla prevents a decrease in striatal synaptosome dopamine (da) uptake, mla significantly attenuates meth-induced neurotoxicity at 72 h post-treatment. mla fully prevents microglial activation at 24 h post-treatment and tending to confirm its neuroprotective activity[4].[1]. kalappa b i, sun f, johnson s r, et al. a positive allosteric modulator of α7 nachrs augments neuroprotective effects of endogenous nicotinic agonists in cerebral ischaemia. brit.j.pharmacol, 2013, 169(8): 1862-1878.[2]. ward j m, cockcroft v b, lunt g g, et al. methyllycaconitine: a selective probe for neuronal α-bungarotoxin binding sites. febs lett, 1990, 270(1-2): 45-48 .[3]. zheng x, et al. methyllycaconitine alleviates amyloid-β peptides-induced cytotoxicity in sh-sy5y cells. plos one, 2014, 9(10): e111536.[4]. escubedo e, et al. methyllycaconitine prevents methamphetamine-induced effects in mouse striatum: involvement of alpha7 nicotinic receptors. j pharmacol exp ther, 2005, 315(2): 658-67.

Biochem/physiol Actions

Methyllycaconitine (MLA) is an α7 nicotinic acetylcholine receptor (α7 nAChR) antagonist. It is a norditerpenoid alkaloid synthesized by several species of Delphinium. MLA binds to the binding site of neuronal α-bungarotoxin. Low doses of MLA are associated with improvement of cognition in animals.
