| Refractive Index | 1.608 |
| Use | A selective inhibitor of Cox-2 |
| In vitro study | Valdecoxib inhibited the production of PGE 2 in plasma induced by LPS, and the degree of COX-2 inhibition was evaluated, and the IC50 was 0.89 μm. Valdecoxib inhibited the production of TxB 2 in plasma, and the degree of inhibition of COX-1 was evaluated, and the IC50 was 25.4 μm. Valdecoxib binds to COX-2 with a Ka of 1.1 × 10 [the percentage of dissolved Valdecoxib is 10.5 for Valdecoxib at 15 minutes (DP 15) and for its hydrophilic derivative (vald-βcd, VALD-HPβCd and VALD-SBE7βCd complexes) were 50%,91% and 93%, respectively. |
| In vivo study | Oral administration of Valdecoxib inhibited carrageenan foot pad edema in rats with an ED50 of 10.2 mg/kg. The oral administration of Valdecoxib has chronic anti-inflammatory activity with an ED50 of 0.032 mg/kg/day in a rat model of nonspecific arthritis. In the rat carrageenan air sacculitis model, oral administration of Valdecoxib blocked prostaglandin production at the site of inflammation with an ED50 of 0.02 mg/kg. Valdecoxib showed significant efficacy in acute and chronic inflammatory rat models (air sacculitis ED50 = 0.06 mg/kg; Foot swelling ED50 = 5.9 mg/kg; non-specific arthritis ED50 = 0.03 mg/kg). Valdecoxib alone was slowly absorbed in vivo, with a maximum percent inhibition of edema of 16% after 3 hours. In contrast, the vald-βcd and VALD-SBE7βCd complexes have a high absorption rate in vivo and are able to inhibit edema by more than 50% within 1 hour, and after 3 hours, the maximum percentage of inhibition of edema is 66%. Valdecoxib (5 mg/kg, P. O.) resulted in plasma AUC of 3.58 μg * H/ml and 2.08 μg * H/ml in male and female rats, respectively. Valdecoxib (5 mg/kg, P. O.) resulted in au c of 12.1 μg * H/ml and 6.42 μg * H/ml in erythrocytes in male and female rats, respectively. |
