NIBR189 is a small molecule antagonist of the Epstein-Barr virus-induced gene 2 (EBI2; GPR183) receptor with IC50 of 16 nM(Binding) and 11 nM (Functional).
NCRW0005-F05, first antagonist selective for GPR139 (IC50 value 0.21 uM); a useful tool to study GPR139 pharmacology, especially in combination with the GPR139 agonist JNJ 63533054.
ML401 is an antagonist of the EBI2 receptor with an IC50 of 1.03 nM. ML401 displays activity in a chemotaxis assay (IC50=6.24 nM). ML401 shows good stability and no toxicity.
ML 145 is a selective GPR35/CXCR8 antagonist with an IC50/EC50 of 20.1 nM, but not for the related GPR55 orphan receptor. GPR35 is expressed by various cells of the immune system and it may has potential as a therapeutic target in inflammatory disease.
ML 193 is a selective GPR55 antagonist (IC50 = 221 nM). Exhibits >27-, >145- and >145-fold selectivity for GPR55 over CB1, GPR35 and CB2, respectively. Inhibits ERK signaling in vitro.
