Secondary mutations of FLT3 have become the main mechanism of FLT3 inhibitor resistance that presents a significant clinical challenge. Herein, a series of pyrazole-3-amine derivatives were synthesized and optimized to overcome the common secondary resistance mutations of FLT3. The structure-activity relationship and molecular dynamics simulation studies illustrated that the ribose region of FLT3 could be occupied to help address the obstacle of secondary mutations. Among those derivatives, compound 67 exhibited potent and selective inhibitory activities against FLT3-ITD-positive acute myeloid leukemia (AML) cells and possessed equivalent potency against transformed BaF3 cells with a variety of secondary mutations. Besides, cellular mechanism assays demonstrated that 67 strongly inhibited phosphorylation of FLT3 and its downstream signaling factors, as well as induced cell cycle arrest and apoptosis in MV4-11 cells. In the MV4-11 xenograft models, 67 exhibited potent antitumor potency without obvious toxicity. Taken together, these results demonstrated that 67 might be a drug candidate for the treatment of FLT3-ITD-positive AML.

, p. 591 - 594 (2007/10/03)
The synthesis of benzimidazole 1 using a liquid phase approach is described. Aromatic substitution of immobilized o-fluoronitrobenzene 2 with various amines to o-nitroaniline derivatives 3 is carried out in methylene chloride. Reduction of the aromatic nitro group, followed by subsequent cyclization/elimination gives the benzimidazole skeleton. The crude library members obtained are of high yields and chemical purities after cleavage.
