Myricetin

A cell-permeable flavanoid that displays anti-inflammatory, anti-diabetic and anti-cancer properties. Acts as a non-ATP competitive MEK1 inhibitor (IC₅₀<3 µM), and ATP-competitive inhibitors of CKI, CKII, IR, MLCK, PKA and PKC (K_i = 9.0 µM, 0.6 µM, 2.6 µM, 1.7 µM, 27.5 µM and 12.1 µM, respectively) and PI 3-Kα and PIM-1 (IC₅₀ = 1.8 µM and 0.78 µM). Reported to inhibit the activities of phosphodiesterase 1-4 (IC₅₀<40 µM) and MMP-2 (IC₅₀<24 µM in several colorectal carcinoma cells), and block TNFα-mediated NF-κB signaling (at 50 µM in ECV304 cells) and insulin-stimulated glucose transport (K_i = ~ 33.5 µM in rat adipocytes). Further, induce apoptosis in HL-60 leukemia cells with an IC₅₀ of 43 µM.
