GNF-7 shows potent antiproliferative activity against wild-type and mutant Bcr-Abl Ba/F3 cells with IC50 less than 11 nM. In human colon cancer cells (Colo205 and SW620), GNF-7 also displays excellent growth inhibitory activity with IC50 of 5 nM and 1 nM, respectively. GNF-7, potently and selectively inhibits NRAS-dependent acute myelogenous leukemia and acute lymphoblastic leukemia cells through combined inhibition of ACK1/AKT and GCK.
In vivo
GNF-7 exhibits excellent pharmacokinetic parameters in mice. In a bioluminescent xenograft mouse model using a transformed T315I-Bcr-Abl-Ba/F3 cell line, GNF-7 (10 mg/kg, p.o.) effectively inhibits tumor growth. In NSG mice bearing human mutant NRAS-expressing MOLT-3-luc+ tumors, GNF-7 (15 mg/kg, p.o.) significantly decreases disease burden, prolongs overall survival, and causes strong suppression of phospho-AKT and phospho-RPS6.
