Targeting autophagy is a promising therapeutic strategy for cancer treatment. As a result, the identification of novel autophagy inhibitors is an emerging field of research. Herein, we report the development of a novel AlphaScreen HTS assay that combined with a MS-based assay and a structure-based high-throughput virtual screening have enabled the identification of benzo[cd]indol-2(1H)-one as a novel
靶向自噬是一种有前途的癌症治疗策略。结果,新型自噬抑制剂的鉴定是一个新兴的研究领域。在本文中,我们报告了结合基于MS的检测和基于结构的高通量虚拟筛选的新型AlphaScreen HTS检测的开发,该检测已将苯并[ cd ] indol-2(1 H)-作为一种靶向Atg4B的新型支架。因此,最初的筛选活动导致鉴定了带有氯醇部分的NSC126353和NSC611216。初始命中的结构-活性关系分析提供了带有7-氨基苯并[ cd]的优化铅化合物33] indol-2- [ 1H ]-一个支架和一个丙基取代氯。还通过测量LC3-II和p62蛋白水平来研究细胞中自噬的抑制作用。此外,33与奥沙利铂联合的协同作用导致人结肠直肠腺癌细胞系HT-29的细胞死亡增加。我们相信,开发的基于AlphaScreen和MS的检测方法可以成为实现高通量鉴定新型Atg4B抑制剂的关键工具。而且,氨基苯并[ cd ]吲哚-2-

A concise and efficientone‐potsynthesis of multi‐halogen pyrazino[1,2‐a]indole‐1,8(2H,5aH)‐dione (MHPID) derivatives by the reaction of an enamino ester with multi‐halogen benzoquinone derivatives is described. MHPIDs 3a–3d were obtained with good yields (78–83%) by refluxing enamino esters 1a and 1b and tetrahalogen‐1,4‐benzoquinones 2a and 2b for 24 h without the use of catalysts. Compounds 3e–3p
