  Discovery of novel N-(5-(tert-butyl)isoxazol-3-yl)-N′-phenylurea analogs as potent FLT3 inhibitors and evaluation of their activity against acute myeloid leukemia in vitro and in vivo

  摘要：

  FLT3 inhibitors have been explored as a viable therapy for acute myeloid leukemia (AML). However, the clinical outcomes of these FLT3 inhibitors were underwhelming except AC220. Therefore, the development of novel FLT3 inhibitors with high potency against both FLT3-WT and FLT3-ITD mutants are strongly demanded at the present time. In this study, we designed and synthesized a series of novel N-(5-(tert-butyl) isoxazol-3-yl)-N'-phenylurea derivatives as FLT3 inhibitors. SAR studies focused on the fused rings led to the discovery of a series of compounds with high potency against FLT3-ITD-bearing MV4-11 cells and significantly inhibitory activity toward FLT3. Among these compounds, N-(5-(tert-butyl) isoxazol-3-yl)-N'-(4-(7-methoxyimidazo[1,2-a]pyridin-2-yl)phenyl) urea (16i), displayed acceptable aqueous solubility, desirable pharmacokinetic profile and high cytotoxicity selectivity against MV4-11 cells. This compound can inhibit phosphorylation of FLT3 and induce apoptosis in a concentration-dependent manner. Further in vivo antitumor studies showed that 16i led to complete tumor regression in the MV4-11 xenograft model at a dose of 60 mg/kg/d while without observable body weight loss. This study had provided us a new chemotype of FLT3 inhibitors as novel therapic candidates for AML. (C) 2015 Published by Elsevier Ltd.

Most examples have acetamido, bromo, cyano, or formyl substituents at the 4′-position. Analogous imidazo-[2,1-b]fhiazoles and imidazo[1,2-a]pyrimidines have also been prepared. Another

  Wnt/β-catenin signaling plays an important role in the regulation of embryonic development and tumorigenesis. Since its deregulation results in severe human diseases, especially cancer, the Wnt signaling pathway constitutes a promising platform for pharmacological targeting of cancer. In this study we synthesized a series of imidazo[1,2-a]pyrimidines and imidazo[1,2-a]pyridines and identified some derivatives that were able to inhibit the Wnt/β-catenin signaling pathway in a luciferase reporter assay and cell proliferation in selected cancer cell lines, endowed with APC or β-catenin gene mutations. The most active compounds significantly downregulate the expression of Wnt target genes such as c-myc and cyclin D1. Further studies indicated that these compounds function independently of GSK-3β activity. More importantly, in vivo experiments, carried out on a Wnt-reporter zebrafish model indicate, in particular for compounds 4c and 4i as the most active compounds, an activity comparable to that of the reference compound IWR1, suggesting their potential use not only as small molecule inhibitors of the Wnt/β-catenin signal in Wnt driven cancers, but also in other Wnt-related diseases.
