Target	COX-2:26 nM (IC50)
In Vitro	SC57666 inhibits COX2 with an IC50 of 3.2±0.8 nM in CHO cells stably transfected with human COX isozymes, with 1000 fold or more selectivity over COX1 (IC50=6000±1900 nM)[2].
In Vivo	SC57666 has been shown to be orally active (ED50=1.7 mpk) in the adjuvant-induced arthritis model. No gastric lesions are observed in mice after 5 h when SC57666 is administered intragastrically at 600 mpk. No intestinal damage is observed in rats after 72 h when SC57666 is administered intragastrically at 200 mpk[1].
