a novel class of utrophin modulators using an improved phenotypic screen, where reporter expression is derived from the full genomic context of the utrophin promoter. We further demonstrate through target deconvolution studies, including expression analysis and chemical proteomics, that this compound series operates via a novel mechanism of action, distinct from that of ezutromid.
Duchenne 型肌营养不良症是一种无法治愈的致命疾病,由缺乏细胞骨架蛋白肌营养不良蛋白引起。utrophin 的上调,一种抗肌萎缩蛋白旁系物,提供了一种独立于突变类型的潜在疗法。一流的 utrophin 调节剂 ezutromid/SMT C1100 在 II 期临床试验中失败,需要开发具有更好功效、理化和 ADME 特性和/或补充机制的化合物。我们已经发现并使用改进的表型筛选对一类新型 utrophin 调节剂进行了初步优化,其中报告基因表达来自 utrophin 启动子的完整基因组背景。我们通过目标去卷积研究进一步证明,包括表达分析和化学蛋白质组学,
