Biological Activity

[Description]:

4'-Hydroxy diclofenac is an orally active metabolite of Diclofenac (HY-15036) by cytochrome P450 2C9 (CYP2C9). 4'-Hydroxy diclofenac has anti-inflammatory and analgesic properties[1][2].

Research Areas >> Neurological Disease

[In Vivo]

A single oral administration of Diclofenac to humanized mice, the unchanged drug in plasma peaks at 0.25 hour and then declines with a half-life (t1/2) of 2.4 hours. 4'-Hydroxy diclofenac also peaks at 0.25 hour and is undetectable within 24 hours. The plasma concentration of unchanged 4'-Hydroxy diclofenac peaks at 0.25 hour and declines rapidly in Humanized chimeric mice received of 4'-Hydroxy diclofenac (10 mg/kg; a single oral)[2].
