In this pilot study, a series of new 3,4-dihydroquinolin-2(1)-one derivatives as potential dopamine receptor D (DR) modulators were synthesized and evaluated in vitro. The preliminary structure-activity relationship disclosed that compound exhibited the highest DR affinity among the newly synthesized compounds. In addition, showed a very low cytotoxic profile and a high probability to cross the blood-brain barrier, which is important considering the observed affinity. However, molecular modelling simulation revealed completely different binding mode of compared to USC-D301, which might be the culprit of the reduced affinity of toward DR in comparison with USC-D301.
