摘要：
The synthesis, preliminary evaluation and structure-activity relationship (SAR) of a series of 1-aryl-4-methyl[1,2,4]triazolo[4,3-a]quinoxalines as dual phosphodiesterase 2/phosphodiesterase 10 (PDE2/PDE10) inhibitors are described. From this investigation compound 31 was identified, showing good combined potency, acceptable brain uptake and high selectivity for both PDE2 and PDE10 enzymes. Compound 31 was subjected to a microdosing experiment in rats, showing preferential distribution in brain areas where both PDE2 and PDE10 are highly expressed. These promising results may drive the further development of highly potent combined PDE2/PDE10 inhibitors, or even of selective inhibitors of PDE2 and/or PDE10. (c) 2012 Elsevier Ltd.
