CAS#: 569-77-7

Description: Purpurogallin is a red, crystalline compound, and the aglycon of several glycosides from nutgalls and oak barks. It can inhibit hydroxyestradiol methylation by catechol-O-methyltransferase. It potently and specifically inhibits PLK, TLR1/TLR2 activation pathway. Purpurogallin showed antiplatelet and antithrombotic activities; anti‑inflammatory effects; antitumor activity, anti-oxidation activities; hepatoprotecting effects; antibacterial activity toward gram-positive bacteria.
