Emodin

A cell-permeable, reversible, substrate competitive and potent p56^lck tyrosine kinase inhibitor (IC₅₀ = 18.5 µM). Selectively blocks the growth of v-ras transformed human bronchial epithelial cells (IC₅₀ = 14.8 µM) without affecting normal human bronchial epithelial cells, even at a concentration of 370 mM. Reported to act as an inhibitor of Tau aggregation and aid in the disassembly of PHF in vitro and in vivo.

Cell permeable: yes

Primary Target
p56^lck tyrosine kinase

Product does not compete with ATP.

Reversible: yes

Target IC₅₀: 18.5 µM against p56lck tyrosine kinase
