生物活性 | NE 52-QQ57 is a selective, and orally availableGPR4antagonist with anIC50of 70 nM. NE 52-QQ57 has anti-inflammatory activity[1]. |
IC50& Target | |
体外研究 (In Vitro) | NE 52-QQ57 effectively blocks GPR4-mediated cAMP accumulation (IC5026.8 nM in HEK293 cells)[2].
|
体内研究 (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[1].
Animal Model: | Female FVB mice (8-10 weeks)[1] | Dosage: | 30 mg/kg | Administration: | Oral, 4 days, bid | Result: | Treatment at 30 mg/kg p.o. bid starting on day 0, the day of the chamber implantation, showed a statistically significant reduction (46.8±10.6%) of tissue growth by day 4. The blood levels of 13 on day 4 at 2 and 16 h after compound application in this model were 9.03±2.87 and 0.09±0.06 μM[1]. |
Animal Model: | Male Wistar Han rats[1] | Dosage: | 3, 10, and 30 mg/kg | Administration: | Oral, 20 days, bid | Result: | Displayed not only higher exposures in the rat AIA but also lower plasma protein binding in rat (95%)[1]. |
