Article Description

Non-motor alterations such as anxiety and memory deficit may represent early indications of Parkinson’s disease (PD), and therapeutic strategies that reduce non-motor alterations are promising alternatives for the treatment. Therefore, the search for natural compounds that act on motor and non-motor complications is highly relevant. In this sense, we demonstrated the role of hesperidin (Hsd) as a citrus flavonoid and its pharmacological properties as an antioxidant and neuroprotective agent. Our objective was to evaluate Hsd in developing motor and non-motor alterations in a Drosophila melanogaster model of Parkinson-like disease induced by iron (Fe) exposure. The flies were divided into six groups: control, Hsd (10 µM), L -dopa (positive control, 1 mM), Fe (1 mM), Fe + Hsd, and Fe +  L -dopa. Motor coordination tests, memory assessment through aversive phototaxy, and anxiety-like behaviors characterized in flies, such as grooming and aggressiveness, were performed. The Hsd attenuated motor and non-motor alterations, such as motor coordination, memory deficits and anxiety-like behaviors, attenuated monoaminergic deficits, and lowered Fe levels in the head of flies. In addition, Hsd prolonged the life of the flies, thereby standing out from the L -dopa-treated group. Thus, Hsd can protect the dopaminergic system from insults caused by Fe, preventing non-motor alterations in PD; Hsd also reduced Fe levels in the flies’ heads, suggesting that iron chelation may represent an important mechanism of action, in addition to its antioxidant action.
