Design, Synthesis, and Biological Evaluation of New Diaminoquinazolines as β-Catenin/Tcf4 Pathway Inhibitors
摘要:
More than 50 new diaminoquinazoline derivatives have been synthesized and evaluated in a colon carcinoma cell growth inhibition assay using HCT116 and SW480 cells. Twenty compounds with good cell growth inhibitory activities (<4 mu M) were tested as inhibitors of the beta-catenin/T cell transcription factor 4 (Tcf4) signaling pathway using a HCT116 cell-based luciferase reporter assay. Results from the biological activities as well as the comparative molecular field analysis (CoMFA) of the properties of the molecules yielded a preliminary structure-activity relationship (SAR). Three potent compounds, 74, 78, and 86, showed IC50 values <1 mu M for growth inhibition of HCT116 cells and similar to 1 mu M for SW480 cells, as well as IC50 values of 1.5-2.5 mu M for HCT116 cells with the luciferase reporter assay.

A method to assemble (hetero)aryl sulfonamides via the reductive coupling of aryl sulfinates and nitroarenes is reported. Various reducing conditions with sodium bisulfite and with or without tin(II) chloride in DMSO were developed using an ultrasound bath to improve reaction homogeneity and mixing. A range of (hetero)aryl sulfonamides bearing a selection of functional groups were prepared, and the
报道了一种通过芳基亚磺酸盐和硝基芳烃的还原偶联组装(杂)芳基磺酰胺的方法。使用超声波浴开发了在 DMSO 中使用亚硫酸氢钠以及含或不含氯化锡 (II) 的各种还原条件,以改善反应均匀性和混合。制备了一系列带有精选官能团的(杂)芳基磺酰胺,并研究了转化机制。这些研究使我们提出了亚硝基芳烃中间体的形成,这是通过独立的分子偶联策略建立的。
