  Investigation of 3-aryl-pyrimido[5,4-e][1,2,4]triazine-5,7-diones as small molecule antagonists of β-catenin/TCF transcription

  摘要：

  Nearly all colorectal cancers (CRCs) and varied subsets of other cancers have somatic mutations leading to beta-catenin stabilization and increased beta-catenin/TCF transcriptional activity. Inhibition of stabilized beta-catenin in CRC cell lines arrests their growth and highlights the potential of this mechanism for novel cancer therapeutics. We have pursued efforts to develop small molecules that inhibit beta-catenin/TCF transcriptional activity. We used xanthothricin, a known beta-catenin/TCF antagonist of microbial origin, as a lead compound to synthesize related analogues with drug-like features such as low molecular weight and good metabolic stability. We studied a panel of six candidate Wnt/beta-catenin/Tcf-regulated genes and found that two of them (Axin2, Lgr5) were reproducibly activated (9-10 fold) in rat intestinal epithelial cells (IEC-6) following beta-catenin stabilization by Wnt-3a ligand treatment. Two previously reported beta-catenin/TCF antagonists (calphostin C, xanthothricin) and XAV939 (tankyrase antagonist) inhibited Wnt-activated genes in a dose-dependent fashion. We found that four of our compounds also potently inhibited Wnt-mediated activation in the panel of target genes. We investigated the mechanism of action for one of these (8c) and demonstrated these novel small molecules inhibit beta-catenin transcriptional activity by degrading beta-catenin via a proteasome-dependent, but GSK3 beta-, APC-, AXIN2- and beta TrCP-independent, pathway. The data indicate the compounds act at the level of beta-catenin to inhibit Wnt/beta-catenin/TCF function and highlight a robust strategy for assessing the activity of beta-catenin/TCF antagonists.

  一类蛋白质二硫键异构酶抑制剂治疗胶质母细胞瘤的发现和机理研究

  摘要：

  蛋白质二硫键异构酶（PDI）在胶质母细胞瘤（脑癌的最具侵略性形式）中过表达，并且折叠负责该疾病进展和传播的新生蛋白质。在这里，我们描述了一种新型的纳摩尔PDI抑制剂，嘧啶三嗪二酮35G8，在一组人胶质母细胞瘤细胞系中具有毒性。我们对1 000 000种化合物的不同子集进行了中通量20000化合物筛查，以鉴定具有细胞毒性的小分子。对细胞毒性化合物进行了PDI抑制作用的筛选，并且从筛选物中发现35G8是PDI最具细胞毒性的抑制剂。新生RNA的溴尿苷标记和测序（Bru-seq）表明35G8诱导类似核因子2（Nrf2）的抗氧化反应，内质网（ER）应激反应和自噬。具体而言，35G8上调了血红素加氧酶1和溶质载体家族7成员11（SLC7A11）的转录和蛋白质表达，并抑制了PDI靶基因，如硫氧还蛋白相互作用蛋白1（TXNIP）和早期生长反应1（EGR1）。有趣的是，35G8诱导的细胞死亡不是通过细胞凋亡
