PDB Ligand
Compound class: Synthetic organic
Comment: FRAX486 is a brain penetrant and orally bioavailable inhibitor of group 1 p21 protein (Cdc42/Rac)-activated kinases (PAK1, PAK2 and PAK3; PAKA subfamily) [2]. Experimental evidence suggests inhibition of PAKs may offer neuroprotective [2-3] and anti-cancer potential.
