IRL-1620 Chemical Properties,Uses,Production
Biological Activity
IRL-1620 is a potent and selective endorphin receptor (endothelin receptor) type B agonist with a Ki of 16 pM.
in vitro
IRL-1620 is the most potent and specific ligand for the ETB receptor (K i ETA/ K i ETB=120,000) as judged by the K i values for ETA (19 μM) and ETB (16 PM) receptors. IRL-1620 is 60 times more selective for the ETB receptor than ET-3 (K i ETA /K i ETB=1,900).
target
IC50: 16 pM (Endothelin receptor B), 19 μM (Endothelin receptor A)
storage
-20°C (desiccate)
