providing insights into the contributions of the two aryl ring systems and highlighting a potent derivative, 3-(5-methoxy, 2-methyl-1H-indol-3-yl)-1-(4-pyridinyl)-2-propen-1-one (i.e., MOMIPP) that can induce methuosis at low micromolar concentrations. We have also generated biologically active azide derivatives that may be useful for future studies aimed at identifying the protein targets of MOMIPP
Methuosis 是一种新的不依赖于半胱天冬酶的细胞死亡形式,其中来自巨松质体的液泡的大量积累最终导致细胞从基质上分离并破裂。我们最近描述了一种查尔酮类化合物,3-(2-methyl-1 H -indol-3-yl)-1-(4-pyridinyl)-2-propen-1-one(即 MIPP),它可以诱导胶质母细胞瘤和其他类型的癌细胞中的甲基化。在此,我们描述了相关化合物定向库的合成和结构-活性关系,提供了对两个芳环系统贡献的见解,并突出了一种有效的衍生物,3-(5-甲氧基,2-甲基-1 H-indol-3-yl)-1-(4-pyridinyl)-2-propen-1-one(即 MOMIPP),可在低微摩尔浓度下诱导甲基化。我们还生成了具有生物活性的叠氮化物衍生物,这些衍生物可能对未来旨在通过光亲和标记技术识别 MOMIPP 的蛋白质靶标的研究有用。MOMIPP 可有效降低替莫唑胺耐药
