Abstract

Drug repurposing has emerged as a promising strategy for expediting drug development by identifying new therapeutic applications for existing drugs. In this study employed in silico screening approach to explore the DrugBank database for potential phosphodiesterase 10 (PDE10) inhibitors with applications in neurological, psychiatric disorders and cancer treatment. PDE10 plays a crucial role in regulating cyclic nucleotide levels in the brain and has been implicated in various diseases, including schizophrenia, Parkinson’s, Huntington’s diseases, and certain types of cancer. Through molecular docking, we evaluated the interactions and energetics of 28 candidate inhibitors with PDE10. Notably, 17 candidates met all selection criteria, presenting excellent potential for further investigation. The theoretical inhibitors demonstrated favorable ADMETx properties, and their adverse effects were comparable or lower than controls. These findings indicate the viability of repurposing existing drugs, such as Nebivolol, Fluvastatin, Pioglitazone and others, for PDE10 inhibition in diverse pathologies. Validation of these candidates in preclinical studies may open new avenues for drug development and clinical applications, addressing unmet medical needs in various disorders and cancer treatment.
