Abstract

Purpose: This study examined the effects of ${\alpha}$-lipoic acid in diluted solvents on cell growth in 3T3-L1 cells according to the treated concentration and times. Methods: Adipocyte 3T3-L1 cell were cultured. Confluent cells underwent starvation with SFM for 1 day and then were cultured in a medium containing various concentrations 0, 100, 200, and $400{\mu}mol/L$ of ${\alpha}$-lipoic acid. The cell viability was measured using the EZ Cytox assay kit. In addition, the effect of ${\alpha}$-lipoic acid of diluted solvents on the cell growth in 3T3-L1cells was examined according to the treated concentration and times. Results: The ${\alpha}$-lipoic acid diluted ethanol inhibited cell proliferation in a dose and time dependent manner. The ${\alpha}$-lipoic acid diluted ethanol induced adipocyte 3T3-L1 cells proliferation with an adipocyte inducer. In addition, ${\alpha}$-lipoic acid inhibited adipocyte 3T3-L1 growth in a dose and time dependent manner (p<0.05). Conclusion: This study showed that a treatment with ${\alpha}$-lipoic acid diluted ethanol inhibits cell growth of, adipocyte 3T3-L1 cells induced with an adipocyte inducer, ($200{\mu}mol/L$ of ${\alpha}$-lipoic acid) treated for 48 hr.
