Abstract

The inhibition of FLT-3 activity is an interesting target for the treatment of acute myeloid leukemia (AML). The serendipitous identification of FLT-3 inhibitors from a CK1/γ-secretase programme provided compounds with dual inhibitory activity. We analyzed the structure– activity relationship of these inhibitors and derivatized them to arrive at compounds with reduced impact on γ-secretase activity and enhanced FLT-3 inhibition.
