Abstract Background Caffeine is a natural alkaloid present in a variety of highly consumed popular drinks such as coffee, tea and soft drinks as well as chocolate. Its consumption elicits beneficiary psychostimulant that has been linked to a reduced risk of developing Parkinson’s disease (PD). The aim of the present study is to investigate the possible synergistic neuroprotective effects of co-administration of caffeine (CAF) or coffee (COF) with rasagiline (R) or l-dopa against paraquat (PQ)-induced neurochemical and motor behavior impairments in mice. Results In behavioral tests, R + COF increased the locomotor activity in rotarod test compared to l-dopa + COF. l-Dopa combinations decreased the immobility time in FST compared to rasagiline combinations; l-dopa + CAF provided a similar increase in locomotor activity compared to R + CAF. Combination of CAF or COF with l-dopa or rasagiline resulted in a substantial improvement in brain neurotransmitter and antioxidant levels as they significantly increased dopamine and super oxide dismutase but significantly decreased nitric oxide levels as compared to l-dopa or rasagiline, respectively. Furthermore, they also exerted a protective effect against the neurodegenerative histopathological changes induced by PQ. Conclusions Our findings demonstrated co-administration of COF or CAF, adenosine 2A receptor antagonists, along with l-dopa or rasagiline possesses a new therapeutic strategy for the management of PD neurochemical disturbances and motor behavior impairments through preservation of the brain dopamine and serotonin content, antioxidants level and histological features.
