The use of the new anticancer tyrosine kinase inhibitors (TKI) has revolutionized the treatment of certain cancers. However, the use of some of these results in cardiotoxicity. Large-scale profiling data recently made available for the binding of 7 of the 9 FDA-approved tyrosine kinase inhibitors to a panel of 317 kinases has allowed us to correlate kinase inhibitor binding selectivity scores with TKI-induced damage to neonatal rat cardiac myocytes. The tyrosine kinase selectivity scores, but not the serine-threonine kinase scores, were highly correlated with the myocyte damaging effects of the TKIs. Additionally, we showed that damage to myocytes gave a good rank order correlation with clinical cardiotoxicity. Finally, strength of TKI binding to colony-stimulating factor 1 receptor (CSF1R) was highly correlated with myocyte damage, thus possibly implicating this kinase in contributing to TKI-induced cardiotoxicity.
