Parkinson's disease (PD) is an adult-onset neurodegenerative condition caused by oxidative stress and mitochondrial malfunction. In this study, the neuroprotective and neuritogenic activity of water fraction (Sw-fr) containing sorbicillin-like active metabolites of halotolerant P. flavigenum isolated from Salt Lake in Konya, Turkey were investigated on a 6-hydroxydopamine (6-OHDA)-induced PD in vitro PC-12 Adh cell model. Firstly, Sw-fr containing sorbicillin-like active metabolites were extracted from P. flavigenum and was compared with a sorbicillin standard by liquid chromatography-mass spectrometry (LC-MS). Then, the effects of non-cytotoxic concentrations of Sw-fr on the 6-OHDA-induced PD cell model were investigated via real-time cell proliferation analysis using the RTCA DP instrument. The effects of these concentrations on mitochondrial membrane integrity, caspase-3 were investigated by flow cytometry. Neurite outgrowth analysis and immunofluorescence staining were used to explore the neuritogenic effects of neuroprotective doses. By improving PC-12 Adh cell viability, decreasing reactive oxygen species production, and reducing apoptotic cell death, 1 and 10 mu g/mL Sw-fr and sorbicillin standard proved neuroprotective against 6-OHDA-induced neurotoxicity. Furthermore, 1 and 10 mu g/mL Sw-fr significantly induced neurite outgrowth. As a result, sorbicillin-like active metabolites containing Sw-fr were found to have neuroprotective and neuritogenic effects. Sorbicillin-like metabolites obtained from fungi may be novel natural medicines for neurodegenerative diseases.
