Abstract
Oxidative stress, glutamate excitotoxicity, and inflammation are the important pathological mechanisms in neurodegenerative diseases. Recently, we reported that 2-cyclopropylimino-3-methyl-1,3-thiazoline hydrochloride protects rat glial cells against glutamate-induced excitotoxicity. In this study, we report the effects of 2-cyclopropylimino-3-methyl-1,3-thiazoline hydrochloride on primary cultured cortical astrocytes after exposure to hydrogen peroxide (H2O2). Pretreatment of cells with 2-cyclopropylimino-3-methyl-1,3-thiazoline hydrochloride prior to H2O2 exposure attenuated the H2O2-induced reductions in cell survival and superoxide dismutase, catalase, glutathione, and glutathione peroxidase activities. It also reduced H2O2-induced increases in reactive oxygen species levels, malondialdehyde content, and production of nitric oxide. These effects were all concentration-dependent. Our results suggest that 2-cyclopropylimino-3-methyl-1,3-thiazoline hydrochloride protects against oxidative stress.
