In Vitro:

NE 52-QQ57 effectively blocks GPR4-mediated cAMP accumulation (IC50 26.8 nM in HEK293 cells).

 

In Vivo:

NE 52-QQ57 (Compound 13) shows a significant anti-inflammatory effect in the rat antigen induced arthritis model after oral administration at 30 mg/kg bid for 20 days[1]. NE 52-QQ57 (30 mg/kg bid po for 4 days) also prevents angiogenesis in the mouse chamber model as well as pain as demonstrated in the rat complete Freund’s adjuvant model.
