collagenase tyrosinase

Etarotene (Arotinoid ethyl sulphone) is an ethylsulfonyl derivative of aloe acid with differentiation-inducing and potentially antitumor activity.Etarotene is a collagenase inhibitor and can be used to study psoriasis.

Taxifolin (Dihydroquercetin) is a flavonoid in many plants such as Taxus chinensis, Siberian larch, Cedrus deodara and so on.

(-)-Taxifolin, the less active enantiomer of Taxifolin, demonstrates vital anti-tyrosinase activity and notable inhibition against collagenase [IC50 = 193.3 μM], and is valued as an essential natural compound with antifibrotic potential, acting as a capable free radical scavenger with antioxidant capacity.

(±)-Taxifolin ((±)-Dihydroquercetin) is the racemate of Taxifolin, a flavonoid with anti-tyrosinase and anti-fibrotic activity, commonly found in onion, silymarin, French maritime pine bark, and Douglas fir bark. It inhibits collagenase with an IC50 value of 193.3 μM and acts as a free radical scavenger with antioxidant capacity.
