| Bioactivity | CMPD101 is a potent, highly selective and membrane-permeable small-molecule inhibitor of GRK2/3 with IC50 of 18 nM and 5.4 nM, respectively. CMPD101 exhibits less selectively against GRK1, GRK5, ROCK-2 and PKCα with IC50s of 3.1 μM , 2.3 μM, 1.4 μM and 8.1 μM, respectively. CMPD101 can be used for the study of heart failure[1]. | ||||||||||||
| Invitro | CMPD101 (100 μM; pre-20 mins) inhibit the internalization of β2AR, remarkably decreases the isoproterenol-induced formation of clathrin-coated vesicles and the β2AR-GFP fusion protein remained on the plasma membrane in HEK-B2 cell line[1].CMPD101 (3-30 μM; pre-30 minutes) produced a robust phosphorylation of Ser375, which is partially inhibited by pretreatment of cells for 30 minutes with 3 μM Cmpd101 and fully blocked by pretreatment with 30 μM Cmpd101. It also inhibits phosphorylation of MOPr at Thr370, Thr376, and Thr379 residues[2].CMPD101 (3-30 μM; pre-30 minutes) does not affect the DAMGO-induced increase in ERK1/2 and Elk-1 phosphorylation, at 30 μM, this compound produces a small increase in basal ERK1/2 phosphorylation in HEK 293 cells expressing HA-MOPrs[2].
