Exposure to aluminum chloride (AlCl3) induces progressive multiregional neurodegeneration in animal models by promoting oxidative stress and neuroinflammation. The current study was designed to assess the potential efficacy of the natural antioxidants celastrol and thymoquinone (TQ) for alleviating AlCl3-induced psychomotor abnormalities and oxidative-inflammatory burden in male albino rats. Four treatment groups were compared: (i) a vehicle control group, (ii) a AlCL3 group receiving daily intraperitoneal (i.p.) injection of AlCl3 (10 mg/kg) for 6 weeks, (iii) a AlCl3 plus TQ (10 mg/kg, i.p.) cotreatment group, and (iv) a AlCl3 plus celastrol (1 mg/kg, i.p.) cotreatment group. Open-field, rotarod, and forced swimming tests were conducted to assess locomotor activity, motor coordination, anxiety-like behavior, and depressive-like behavior. Acetylcholine (ACh), dopamine, and serotonin levels were measured in brain homogenates. Malondialdehyde (MDA), total antioxidant capacity (TAC), and catalase activity were measured as oxidative stress markers, while tumor necrosis factor-α (TNF-α) and interlukin-6 (IL-6) expression levels were measured as inflammatory markers. Brain derived neurotrophic factor (BDNF) mRNA was measured as an index for the endogenous neuroprotective response. Daily AlCl3 injection reduced free ambulation, impaired motor coordination, promoted anxiety- and depression-like behaviors, reduced whole-brain ACh, dopamine, and serotonin concentrations, increased MDA accumulation, reduced TAC, elevated TNF-α and IL-6, and suppressed BDNF mRNA expression. All of these effects were significantly reversed by TQ or celastrol cotreatment. Thus, TQ and celastrol may be promising treatments for AlCl3-induced neurotoxicity as well as neurodegenerative diseases involving oxidative stress and neuroinflammation. Display omitted •AlCl3 produces psychomotor disturbances and muscle incoordination in male rats.•AlCl3 reduces brain neurotransmitters (Acetylcholine, dopamine and serotonin).•AlCl3 increases brain oxido-inflammatory burden and reduces expression of BDNF.•Thymoquinone ameliorated the behaviors, BDNF expression and biochemical deficits.•Celastrol improved the behaviors and downregulated the oxido-inflammatory burden.
