Methyllycaconitine citrate is a specific antagonist ofα7 neuronal nicotinic acetylcholine receptor(α7nAChR).

α7nAChR^[1]

Pretreatment with 5 and 10 μM Methyllycaconitine citrate (MLA) inhibits the decreased cell viability induced by Aβ_25-35. Cell viability does not decrease after exposure to Methyllycaconitine citrate (2.5, 5, 10, 20 μM). Aβ_25-35treatment increases LC3-II levels, which is inhibited by administration of Methyllycaconitine citrate. Methyllycaconitine citrate also inhibits Aβ-induced autophagosome accumulation in SH-SY5Y cells. Flow cytometry also demonstrates decreased MDC-labeled vacuoles with Methyllycaconitine citrate treatment^[1].

Methyllycaconitine citrate (MLA) (6 mg/kg) given alone intraperitoneally does not cause climbing behavior when compare with the saline group. Pretreatment with Methyllycaconitine citrate significantly inhibits methamphetamine (METH)-induced climbing behavior, by about 50%. Methyllycaconitine citrate does not modify either basal locomotor activity or METH-induced hyperlocomotion. The METH-induced depletion of dopamine neuron terminals is attenuated in mice pretreated with Methyllycaconitine citrate (250±43 fmol/mg, n=7). A direct effect of Methyllycaconitine citrate on body temperature is ruled out because Methyllycaconitine citrate does not affect basal body temperature (37.0±0.5℃, n=5) or reduce the METH-induced hyperthermia (38.2±0.4℃, n=6, MLA+METH group, n.s. versus METH group)^[1].
