Amounting evidences demonstrated that Rho/Rho-associated kinase (ROCK) might be a novel target for the therapy of Parkinson's disease (PD). Recently, we synthesized L-F001 and revealed it was a potent ROCK inhibitor with multifunctional effects. Here we investigated the effects of L-F001 in PD models. We found that L-F001 potently attenuated 6-OHDA-induced cytotoxicity in PC12 cells and significantly decreased intracellular reactive oxygen species (ROS), prevented the 6-OHDA-induced decline of mitochondrial membrane potential and intracellular GSH levels. In addition, L-F001 increased Akt and GSK-3beta phosphorylation and induced the nuclear Nrf2 and HO-1 expression in a time- and concentration-dependent manner. Moreover, L-F001 restored the levels of p-Akt and p-GSK-3beta (Ser9) as well as HO-1 expression reduced by 6-OHDA. Those effects were blocked by the specific PI3K inhibitor, LY294002, indicating the involvement of Akt/GSK-3beta pathway in the neuroprotective effect of L-F001. In addition, L-F001 significantly attenuated the tyrosinehydroxylase immunoreactive cell loss in 1-methyl-4-phenyl-1,2,3,6 tetrahydropyridine (MPTP)-induced mice PD model. Together, our findings suggest that L-F001 prevents 6-OHDA-induced cell death through activating Akt/GSK-3beta and Nrf2/HO-1 signaling pathway and attenuates MPTP-induced dopaminergic neuron toxicity in mice. L-F001 might be a promising drug candidate for PD.
