Aminoindan (1 μM) | 34 | 33 | 30 | 156 |

Neuroprotective effect of MAO B inhibitors, rasagiline, and selegiline, as compared to 1-R-aminoindan (a major metabolite of rasagiline) on the inhibition of MAO B and the survival of a GAPDH-overexpressed cell line (U-118 MG) in ethanol-induced cell death (75 mM; 48 h for mRNA level or 72 h for catalytic activity, H2O2 generation and cell viability analysis). Controls were values obtained from Fig. 4, lane 7 (without drug treatment) which were taken as 100. Data represent the average of three independent experiments.
