Protocol

Cell experiment:

The NSC34 cells are seeded at a density of 7000 cells per well into 96-well plates with D-MEM and transfected using Lipofectamine 2000 mixed with 2 μg /mL of plasmid vector in D-MEM for 6 h. After 6 h, the cell-culture medium is replaced with fresh D-MEM and culture and allowed to proceed for a further 42 h. The cells are then transferred to serum-free D-MEM and immediately treated with Cutamesine at a final concentration of 1, 3, or 10 nM[2].

Animal experiment:

Mice: Transgenic female mice overexpressing mutated human SOD1G93A are used in the study. Cutamesine is dissolved in saline and subcutaneously administered at a dose of 1 mg/kg once daily to 5-week-old SOD1G93A mice to the time of death. In a control group, vehicle (saline) is subcutaneously administered at 10 ml/kg[2].

Background

Cutamesine dihydrochloride (SA4503 dihydrochloride; AGY94806 dihydrochloride) is a potent Sigma 1 receptor agonist with an IC50 of 17.4 nM in guinea pig brain membranes.

The sigma receptor might be involved in several diseases in the central nervous system. Cutamesine, a potent σ1receptor agonist, has 103-fold higher affinity for σ1 (IC50=17.4 nM) than σ2 (IC50=1,784 nM) sites in guinea pig brain membranes. Cutamesine is 14-fold selective for σ1 (Ki=4.6 nM) over σ2 (Ki=63.1 nM) sites in guinea pig brain homogenates[1]. Cutamesine protects motor neuron NSC34 cells against superoxide dismutase 1 and serum free neurotoxicity. It upregulates the phosphorylation levels of Akt and extracellular signal-regulated kinase (ERK) 1/2[2]. Cutamesine reduces the activation of the MAPK/ERK pathway and down-regulated the ionotropic glutamate receptor, GluR1[3].

Cutamesine extends the survival time in the SOD1G93A mice[2].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
