(±)-Taxifolin-13C3

(±)-Taxifolin-13C3 ((±)-Dihydroquercetin-13C3) is a derivative of (±)-Taxifolin, labeled with 13C3. (±)-Taxifolin is the racemate of Taxifolin. Taxifolin exhibits important anti-tyrosinase activity. Taxifolin exhibits significant inhibitory activity against collagenase with an IC₅₀ value of 193.3 μM . Taxifolin is an important natural compound with antifibrotic activity. Taxifolin is a free radical scavenger with antioxidant capacity .

Nonanal-d2

Nonanal-d₂ is deuterated labeled Methyl cinnamate (HY-W017212). Methyl cinnamate (Methyl 3-phenylpropenoate), an active component of Zanthoxylum armatum, is a widely used natural flavor compound. Methyl cinnamate (Methyl 3-phenylpropenoate) possesses antimicrobial activity and is a tyrosinase inhibitor that can prevent food browning. Methyl cinnamate (Methyl 3-phenylpropenoate) has antiadipogenic activity through mechanisms mediated, in part, by the CaMKK2-AMPK signaling pathway .
