Various action pathways of dimebolin affecting memory
Pathway | Dose/concentration of dimebolin used | Study |

Mechanism involving H1 blockade | Data not available | Mateeva et al. 1983 |
Inhibitory effect on the deamination in basal ganglia and hypothalamus | 100 μM in vitro | Shadurskaia et al. 1986 |
Inhibits neurotoxin (AF64A)‐ induced neurodegeneration | 1mg/kg body weight injected intraperitoneally | Lermontova et al. 2000 |
Protected cerebellar neurons against the action of β‐amyloid, anticholinestrase activity, NMDA blocking activity, inhibition of potential‐dependent Ca2+ uptake | 25 μM concentration in cultured neurons; IC50 = 57 μM for effect on Ca2+ uptake; IC50 = 7.9 μM; and 42 μM for butyrylcholine esterase and acetylcholine esterase, respectively; NMDA blocking activity at EC50 = 42 ± 6 mg/kg intraperitoneal | Bachurin et al. 2001 Lermontova et al. 2001 |

NMDA receptor antagonist at high concentrations, and at low dose acts as positive modulator of AMPA receptors | Above 6 μM, blocked NMDA‐ induced currents, above 0.2 μM for AMPA‐modulating effect | Grigorev et al. 2003 |
NMDA blocking and protective effects against glutamate‐induced apoptosis | IC 50 = 10 μM for NMDA blocking effects; and higher concentration of 50 μM for protection against glutamate‐induced | Wu et al. 2008 |
Activity on 5‐HT6 receptors may affect short‐term memory | K(i) = 26.0+/−2.5nM (IC50 = 0.89 μM) | Schaffhauser et al. 2009, Ivachtchenko et al. 2009 |
Increased expression of β‐amyloid excretion | Intraperitoneal injection 3.5 mg/kg, Extracellular concentration of 1–10 μM | Cirrito et al. 2009; Gandy et al. 2009 |
