Bioactivity Comments
Compound 101 is selective for the GRK2 subfamily (GRK2 and GRK3) of G protein-coupled receptor kinases [3]. Subsequent profile screening (of 58 kinases representative of the entire kinome, excl. lipid kinases) identifies only 5 off-target kinases inhibited by compound 101 by >50% (@ 1μM): protein kinase C related protein kinase (PRK2), serum and glucocorticoid regulated kinase (SGK1), ribosomal protein S6 kinase, 90kDa, polypeptide 1 (RSK1) , ribosomal protein S6 kinase, 90kDa, polypeptide 5 (MSK1) and ribosomal protein S6 kinase, 70kDa, polypeptide 1 (S6K1) [2].
A role for these GPCR-related kinases in desensitisation of activated μ opioid receptors is identified by experiments showing that compound 101-induced inhibition of GRK2/3 partially reverses agonist-induced desensitisation of the μ opioid receptor [2].
