Publication Abstract from PubMed
Many clinically validated kinases, such as BCR-ABL, c-Kit, PDGFR, and EGFR, become resistant to adenosine triphosphate-competitive inhibitors through mutation of the so-called gatekeeper amino acid from a threonine to a large hydrophobic amino acid, such as an isoleucine or methionine. We have developed a new class of adenosine triphosphate competitive inhibitors, exemplified by HG-7-85-01, which is capable of inhibiting T315I- BCR-ABL (clinically observed in chronic myeloid leukemia), T670I-c-Kit (clinically observed in gastrointestinal stromal tumors), and T674I/M-PDGFRalpha (clinically observed in hypereosinophilic syndrome). HG-7-85-01 is unique among all currently reported kinase inhibitors in having the ability to accommodate either a gatekeeper threonine, present in the wild-type forms of these kinases, or a large hydrophobic amino acid without becoming a promiscuous kinase inhibitor. The distinctive ability of HG-7-85-01 to simultaneously inhibit both wild-type and mutant forms of several kinases of clinical relevance is an important step in the development of the next generation of tyrosine kinase inhibitors.
