Hello Bio announces launch of Cmpd101

Today Hello Bio announced the launch of a novel, potent and selective G-protein coupled receptor kinase 2 and 3 (GRK2/3) inhibitor, Cmpd101.

GRKs are key regulators of GPCR dependent and independent signalling pathways and play a crucial role in GPCR desensitization – the deactivation of GPCR elicited signalling. Hypo/hyper activity of GRKs have been linked to many pathophysiologies.

A recent Molecular Pharmacology paper by Lowe et al shows Cmpd101 to be a potent and selective GRK2/GRK3 inhibitor (IC50 values are 35, 290 nM and 125 μM at GRK2, GRK3 and GRK5 respectively). It is cell permeable and can be used to study the roles of GRK2/3 in GPCR desensitization and other functions.

“Our team are particularly excited by this new GRK inhibitor- until now there haven't been many commercially available tools to selectively modulate GRK2 and 3 - so the launch of Cmpd101 should really help researchers investigate this key kinase.” Steve Roome, co-founder and Managing Director of Hello Bio

Hello Bio is the first life science supplier to offer Cmpd101 and it joins the company’s fast- growing range of affordable tools, which include opioid receptor tools such as DAMGO, Naloxone and Endomorphin-1 as well as many signalling and receptor tools: PD 98059, Y-27632, D-AP5, NBQX disodium salt and more.
