Description

GRK5-IN-3 is a covalent inhibitor of GRK5 (G Protein-Coupled Receptor Kinase 5). GRK5-IN-3 shows potent inhibitory effect to GRK5 and GRK6 with IC50s of 0.22 μM and 0.41 μM, respectively[1].

IC50 & Target

IC50: 0.22 μM (GRK5), 0.41 μM (GRK6)[1]

In Vitro

GRK5 can be used to cancer, neurodegeneration, type 2 diabetes, heart failure and cardiovascular (CVD) research[1].
GRK5-IN-3 (Compound 5) (0-333 μM; 0-4 h) inhibits GRK5 in a time-dependent manner with IC50s of 59 μM (0 h), 11.3 μM (0.5 h), 6.2 μM (1 h), and 0.22 μM (4 h), respectively[1].
GRK5-IN-3 (0-333 μM; 0-4 h) also shows selectivity to human GRK5 over bovine GRK2 and bovine GRK1, with IC50s >100 μM (GRK1/2), respectively[1].
GRK5-IN-3 (0-333 μM; 0-4 h) exerts inhibition against GRK5, while light activated ROS as substrate, with IC50s of >100 μM (0 h), 4.2 μM (0.5 h), 3.4 μM (1 h), and 0.9 μM (4 h), respectively[1].
GRK5-IN-3 (0-333 μM; 4 h) shows no inhibitory effect on mutant GRK5 (GRK5-C474S, Cys474 mutated to serine), with IC50 values >100 μM[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
