GNF-6

GNF-6 (Compound 14), an ATP competitive inhibitor, inhibits the gatekeeper threonine residue mutation of BCR-ABL-T315I with IC50 values of 0.25 μM for c-ABL-T334I, 0.09 μM for BCR-ABL, and 0.590 μM for BCR-ABL-T315I variants. It disrupts the assembly of the hydrophobic spine (a network of hydrophobic interactions), locking the kinase in an inactive 'DFG-out' conformation [1].
