GTP-14564 is a novel tyrosine kinase inhibitor that also inhibits wt-FLT3 and ITD-FLT3.

(±)-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.

Tyrosinase-IN-2 (compound 67) is a potent inhibitor of tyrosinase, a copper-containing metalloenzyme crucial for the rate-limiting step in melanin biosynthesis and enzymatic browning processes.
