  Discovery of 6-phenylimidazo[2,1-b]thiazole derivatives as a new type of FLT3 inhibitors

  摘要：

  In this investigation, a series of 6-phenylimidazo[2,1-b] thiazole derivatives were synthesized. Structure-activity relationship (SAR) analysis of these compounds based on cellular assays led to the discovery of a number of compounds that showed potent activity against FLT3-dependent human acute myeloid leukemia (AML) cell line MV4-11, but very weak or no activity against FLT3-independent human cervical cancer cell line Hela. FLT3 kinase inhibition assays were then performed on the three most active compounds. Among these compounds, 6-(4-(3-(5-(tert-butyl)isoxazol- 3-yl)ureido)phenyl)-N-(3-(dimethylamino)propyl)imidazo[2,1-b]thiazole-3-carboxamide (19) exhibited the highest potency in both cellular (MV4-11, IC50: 0.002 mu M) and enzymatic (FLT3, IC50: 0.022 mu M) assays. Further in-depth in vitro anti-AML activity and mechanism of action studies were carried out on compound 19. (C) 2015 Elsevier Ltd. All rights reserved.
