Description
Compound 101 (GRK2 inhibitor 101, Takeda compound 101, Cmpd101) is a novel membrane-permeable, small-molecule inhibitor of GRK2 and GRK3; inhibits the desensitization of the G protein-activated inwardly-rectifying potassium current evoked by receptor-saturating concentrations of Met-Enk, DAMGO, endomorphin-2, and morphine in rat and mouse locus coeruleus neurons; produces complete inhibition of DAMGO-induced MOPr phosphorylation at Ser (375), arrestin translocation, and MOPr internalization in HEK 293 cells
