生物活性
ONO-AE3-208 is an orally active prostaglandin E2 receptor 4 (EP4)-selective antagonist (Ki in nM = 1.3/EP4, 30/EP3, 790/FP and 2400/TP; Ki >10 μM for prostanoid receptors DP, EP1, EP2, IP). Both EP4-/- mice and ONO-AE3-208-treated wild-type mice (10 mg/kg/day in drinking water) are shown to develop severe symptoms (diarrhea, hemoccult, weight loss) in a murine model of DSS-induced colitis. ONO-AE3-208 is also reported to promote ductus arteriosus constriction among fetal and neonatal ratsin vivo(10 mg/kg administered orogastrically). In addition, ONO-AE3-208 is demonstrated to effectively inhibit 1 ng/mL IL-1β-induced HUVEC migration in vitro (53% and 75% inhibition by 1 or 10 μM AE3-208, repectively) and block IL-1β (30 ng/Hydron pellet implant)-induced angionesis in mouse corneasin vivo(1 mg/kg/day p.o.).

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
