GNF-7, a multitargeted kinase inhibitor, served as a dual kinase inhibitor of ACK1 and GCK, which provided a novel therapeutic strategy for overriding AML expressing NRAS mutation. This SAR study with GNF-7 derivatives, designed to target NRAS mutant-driven AML, led to identification of the extremely potent inhibitors, 10d, 10g, and 11i, which possess single-digit nanomolar inhibitory activity against both ACK1 and GCK. These substances strongly suppress proliferation of mutant NRAS expressing AML cells via apoptosis and AKT/mTOR signaling blockade. Compound 11i is superior to GNF-7 in terms of kinase inhibitory activity, cellular activity, and differential cytotoxicity. Moreover, 10k possessing a favorable mouse pharmacokinetic profile prolonged life-span of Ba/F3-NRAS-G12D injected mice and significantly delayed tumor growth of OCI-AML3 xenograft model without causing the prominent level of toxicity found with GNF-7. Taken together, this study provides insight into the design of novel ACK1 and GCK dual inhibitors for overriding NRAS mutant-driven AML.

The present invention provides a therapeutic agent of acute myeloid leukemia containing a 1,3,7-trisubstituted 3,4-dihydropyrimido[4,5-d]pyrimidine-2(1H)-one compound as an active ingredient, which has proliferation inhibitory activity for a human acute myeloid leukemia cell line OCI-AML3 having a NRAS mutant gene while having low inhibitory activity for wild type NRAS and has activity of inhibiting GCK and ACK1 protein kinases at the same time.

The second generation of Bcr-Abl inhibitors nilotinib, dasatinib, and bosutinib developed to override imatinib resistance are not active against the T315I "gatekeeper" mutation. Here we describe a type-II T315I inhibitor 2 (GNF-7), based upon a 3,4-dihydr
