BackgroundParkinson's disease (PD) is an irreversible, progressive disorder that profoundly impacts both motor and non-motor functions, thereby significantly diminishing the individual's quality of life. Dihydrosinularin (DHS), a natural bioactive molecule derived from soft corals, exhibits low cytotoxicity and anti-inflammatory properties. However, the therapeutic effects of DHS on neurotoxins and PD are currently unknown.ObjectiveThis study investigated whether DHS could mitigate 6-hydroxydopamine (6- OHDA)-induced neurotoxicity and explored the role of neuroprotective PI3K downstream signaling pathways, including that of AKT, ERK, JNK, BCL2, and NFκB, in DHS- mediated neuroprotection.MethodsWe treated the human neuroblastoma cell line, SH-SY5Y, with the neurotoxin 6-OHDA to establish a cellular model of PD. Meanwhile, we assessed the anti-apoptotic and neuroprotective properties of DHS through cell viability, apoptosis, and immunostaining assays. Furthermore, we utilized the PI3K inhibitor LY294002 to validate the therapeutic target of DHS.ResultsBased on the physicochemical properties of DHS, it can be inferred that it has promising oral bioavailability and permeability across the blood-brain barrier (BBB). It was demonstrated that DHS upregulates phosphorylated AKT and ERK while downregulating phosphorylated JNK. Consequently, this enhances the expression of BCL2, which exerts a protective effect on neuronal cells by inhibiting caspase activity and preventing cell apoptosis. The inhibition of PI3K significantly reduced the relative protective activity of DHS in 6-OHDA-induced neurotoxicity, suggesting that the neuroprotective effects of DHS are mediated through the activation of PI3K signaling.ConclusionBy investigating the mechanisms involved in 6-OHDA-induced neurotoxicity, we provided evidence concerning the therapeutic potential of DHS in neuroprotection. Further research into DHS and its mechanisms of action holds promise for developing novel therapeutic strategies for PD.
