Biological Activity
Tazarotene is transformed to tazarotenic acid with the help of esterases. Tazarotenic acid regulates the pathogenic aspects of psoriasis through normalizing abnormal keratinocyte differentiation. It possesses strong anti-hyperproliferative effects in skin and reduces inflammation.', 'Tazarotenic acid, an active metabolite of tazarotene, is a potent and selective agonist of the retinoid receptor (RAR) th at binds to RARα, RARβ, and RARγ. Tazarotenic acid relatively selective activates RARβ and RARγ. Tazarotenic acid is a first xenobiotic substrate of human retinoic acid hydroxylase CYP26A1 and CYP26B1.
