PDE10-IN-1 is primarily utilized in research and development within the pharmaceutical and biochemical fields. Its main application lies in its role as a selective inhibitor of phosphodiesterase 10 (PDE10), an enzyme that plays a significant role in regulating intracellular signaling pathways. By inhibiting PDE10, this compound helps in studying the enzyme's function and its impact on various physiological processes, particularly in the central nervous system. Researchers employ PDE10-IN-1 to explore potential therapeutic strategies for neurological and psychiatric disorders, such as schizophrenia, Huntington's disease, and Parkinson's disease. Additionally, it is used in preclinical studies to understand the mechanisms of PDE10 inhibition and to evaluate the efficacy and safety of new drug candidates targeting this enzyme. Its application extends to the development of biomarkers and diagnostic tools for diseases associated with PDE10 dysregulation.
