摘要: The ATP-competitive inhibitors dasatinib and nilotinib, which bind to catalytically different conformations of the Abl kinase domain, have recently been approved for treatment imatinib-resistant CML. These two new drugs, albeit very efficient against most mutants Bcr-Abl, fail effectively suppress Bcr-Abl activity T315I (or gatekeeper) mutation. Generating ATP site-binding drugs that target in has hampered, amongst others, by selectivity, is frequently an issue when developing inhibitors. Recently, using unbiased cellular screening approach, GNF-2, a non-ATP-competitive inhibitor, identified demonstrates transformed cells. exquisite selectivity GNF-2 due finding it targets myristate binding site located near C-terminus as demonstrated genetic approaches, solution NMR X-ray crystallography. like myristate, able induce and/or stabilize clamped inactive conformation analogous SH2-Y527 interaction Src. molecular mechanism allosteric inhibition inhibitor class, combined effects with such nilotinib imatinib on wild-type mutants, particular gatekeeper mutant, are reviewed.
