Isatin (indol-2,3-dione) is an endogenous regulator found in humans and animals. It interacts with numerous target proteins and exhibits a wide range of biological activities, including neuroprotective action in animal models of Parkinson's disease (PD) induced by administration of neurotoxins MPTP (1-methyl-4-phenyl-1,2,3,6- tetrahydropyridine) or rotenone. An antipsychotic drug haloperidol, which impairs neurotransmitter balance in the nigrostriatal pathway, models dopamine deficiency and promotes the development of motor disorders characteristic of PD. In this work, the effect of two doses of isatin (10 mg/kg and 80 mg/kg) on the haloperidol catalepsy and on the proteomic profile of mice brain was investigated. The pretreatment of animals with isatin (1 h before haloperidol administration) reduced the occurrence of haloperidol catalepsy. The administration of haloperidol and also isatin with haloperidol influenced the relative content of a number of proteins associated with PD and other neurodegenerative diseases.
