A2AAR/hMAO-B-IN-1 (compoudn 17) is a non-xanthine dual-target inhibitor targeting the A2A adenosine receptor (A2AAR) (IC50: 34.9 nM) andMAO-B (Ki: 39.5 nM, human) . A2AAR/hMAO-B-IN-1 inhibits A2AAR-induced cAMP accumulation and exhibits competitive, reversible inhibition of MAO-B. A2AAR/hMAO-B-IN-1 can be used in the study of neurodegenerative diseases such as Parkinson's disease (PD) [1].
