Parkinson's disease is a neurodegenerative disease caused by the loss of dopaminergic neurons in the
substantia nigra pars compacta region. An important mechanism contributing to its development is oxidative
stress, induced by the imbalance between the endogenous antioxidant defenses and free radicals production. Naturally
occurring bioactive compounds exhibit high antioxidant capacity that may help reducing oxidative stress and
even reverse the damage induced by ROS. Fruits are particularly rich in phytochemicals with antioxidant effect,
and their properties against the development of neurodegenerative diseases are of great interest. This review discusses
how the fruits bioactive compounds and synthetic analogs have been assessed for their ability to regulate
molecular pathways involved in neuronal survival such as MAPK, Nrf2, and NF-κB, thus elucidating the possible
therapeutic and neuroprotective actions of these compounds.
Keywords: Parkinson's Disease, phytochemicals, neuroprotective fruits, signaling pathways, transcription factors, dopaminergic neurons.
