LDK-378 dihydrochloride Usage And Synthesis

Biological Activity

ldk378 is a highly potent inhibitor of anaplastic lymphoma kinase (alk), which is a receptor tyrosine kinase belonging to the superfamily of insulin receptor, with half maximal inhibitory concentration ic50 of 200 pm. ldk378 also exhibits modest to high inhibition against a panel of other kinases, in which only three kinases with ic50 below 100 nm includes igf-1r (8 nm), insr (7 nm) and stk22d (23 nm). in previous studies, ldk378 has been found to inhibit the proliferation of ba/f3 cells transfected with the npm-alk fusion gene and karpas 299 human non-hodgkin’s ki-positivr large cell lymphoma harboring the npm-alk fusion gene with ic50 of 22.8 nm and 26 nm.
