Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease, selectively involving the upper and lower motor neurons. Glutamate excitotoxicity and oxidative stress are important mechanisms for the pathogenesis of ALS. Nuclear-factor erythroid 2-related factor 2 (Nrf2) is a master transcriptional regulator of many cytoprotective genes. Nrf2 signal pathway could induce a series of antioxidant enzyme, anti-inflammatory and antitoxic protein. The expression of these antioxidant enzymes and antioxidant proteins in nervous system exhibited broad neuroprotection against injury by glutamate. Diallyl trisulfide (DATS) was previously shown to induce many Nrf2 target genes in non-nervous cells. Our studies have shown that DATS at 50 microM caused activation of Nrf2 and Nrf2 target gene in rat spinal cord explants. DATS also protected motor neurons against glutamate-induced excitotoxicity. These have identified DATS as a promising neuroprotective agent and suggest that the activation of Nrf2 signal pathway may be a new strategy in neurodegeneration disease.

Diallyl trisulfide (DATS) is one of the major constituents in garlic oil and has been documented to transcriptionally activate phase II enzymes. The purpose of this study is to evaluate the effects of DATS in prolonging disease duration and survival in a transgenic mouse model of amyotrophic lateral sclerosis (ALS). SOD1-G93A transgenic mice were randomly divided into DATS-treated group (80mg/kg/d, p.o.) and vehicle-treated group at disease onset stage. Oral administration of DATS beginning at clinical onset stage significantly prolonged disease duration and extended life span for about one week. DATS treatment induced HO-1 and reduced GFAP expression in the lumbar spinal cord of SOD1-G93A transgenic mice. This study indicates that DATS has multifunctional neuroprotective effects in SOD1-G93A transgenic mice.
