Chronic Unpredictable Mild Stress (CUMS) is a well-established model for inducing behavioral, cognitive, neurochemical, and metabolic impairments associated with neurobehavioral alterations. This study assessed the neuroprotective, antidepressant, and metabolic regulatory effects of Lonafarnib, a selective farnesyltransferase inhibitor, in mice subjected to chronic unpredictable mild stress (CUMS) for 28 days. The in silico docking analysis revealed encouraging binding energies of Lonafarnib with AChE (- 11.58 kcal/mol), CRF1 (- 10.94 kcal/mol), BDNF (- 5.99 kcal/mol), 5HT1A (- 10.48 kcal/mol), and 5HT2A (- 10.77 kcal/mol). This suggests a potential structural compatibility with cholinergic, serotonergic, neurotrophic, and stress-related proteins as preliminary results which requires experimental validation. The in -vivo study of Lonafarnib (20 or 40 mg/kg, i.p.) were effective in preventing the neurobehavioral alterations in CUMS mice. As, the behavioral evaluations demonstrated that CUMS resulted in anxiety-like behaviors, depressive-like behaviors, and cognitive impairments (p < 0.0001), all of which were significantly alleviated by Lonafarnib, particularly at a dosage of 40 mg/kg. The administration of Lonafarnib resulted in significant improvements in behavioral performance, a reduction in oxidative and inflammatory markers (IL-6, TNF-α), stabilization of HPA-axis related parameters, normalization of corticosterone, glucose, and lipid profiles, along with an increase in BDNF levels. Histological findings also indicated the preservation of neuronal structure within the hippocampus. In conclusion, these findings suggest that Lonafarnib may offer protective advantages against neurobehavioral and metabolic dysfunction caused by CUMS. However, a comprehensive mechanistic validation of prenylation-dependent signaling pathways is essential for further investigation.
