Acute myeloid leukemia (AML) is the most aggressive type of blood cancer, and there is a continued need for new treatments that are well tolerated and improve long-term survival rates in patients. Induction of differentiation has emerged as a promising alternative to conventional cytotoxic chemotherapy, but known agents lack efficacy in genetically distinct patient populations. Previously, we established a phenotypic screen to identify small molecules that could stimulate differentiation in a range of AML cell lines. Utilising this strategy, a 1,5-dihydrobenzo[e][1,4]oxazepin-2(3H)-one hit compound was identified. Herein, we report the hit validation in vitro, structure-activity relationship (SAR) studies and the pharmacokinetic profiles for selected compounds.
急性髓系白血病(AML)是最具侵略性的血液癌症类型,目前仍然需要新的治疗方法,这些方法应具有良好的耐受性,并能提高患者的长期生存率。诱导分化已经成为一种有希望替代传统细胞毒性化疗的方法,但已知的药物在遗传上不同的患者群体中缺乏疗效。之前,我们建立了一种表型筛选方法,用以识别能够在一系列AML细胞系中刺激分化的 small molecules(小分子)。利用这种策略,我们识别出了一种1,5-二氢苯并[e][1,4]恶嗪-2(3H)-酮的击中化合物。本文中,我们报告了该击中化合物的体外验证、结构-活性关系(SAR)研究以及选定化合物的药代动力学特征。
