G 5555 is a high affinity group 1 PAK (pan-PAK1, 2 and 3) inhibitor (Ki = 3.7 nM; pMEK IC50 = 69 nM). Of 235 kinases tested, other than PAK1, eight (PAK2, PAK3, KHS1, Lck, MST3, MST4, SIK2, and YSK1) were inhibited >70%. Exhibits low hERG channel activity (<50% inhibition at 10 μM). Orally bioavailable.
