制备方法与用途

生物活性

3-甲基二硫代呋喃黄素是蛋白质二硫键异构酶 (PDI) 的有效抑制剂,其 IC50 值为 170 nM。

靶点

IC50: 170 nM (PDI)。

体外研究

3-甲基二硫代呋喃黄素是一种强效的蛋白质二硫键异构酶(PDI)抑制剂,其 IC50 值为 170 nM。在人胶质母细胞瘤细胞系中,3-甲基二硫代呋喃黄素表现出毒性作用,并且从筛选结果来看,它是 PDI 的最具有细胞毒性的抑制剂之一。

溴尿嘧啶标记和测序(Bru-seq)结果显示,3-甲基二硫代呋喃黄素可以诱导 Nrf2 抗氧化反应、内质网应激反应以及自噬。具体来说,该化合物上调了血红素加氧酶 1 和 SLC7A11 的转录和蛋白质表达,并抑制了 PDI 目标基因如 TXNIP 和 EGR1 的表达。

值得注意的是,3-甲基二硫代呋喃黄素诱导的细胞死亡并非通过凋亡或坏死途径,而是通过自噬和铁死亡混合的方式进行。

  • Discovery and Mechanistic Elucidation of a Class of Protein Disulfide Isomerase Inhibitors for the Treatment of Glioblastoma

    Protein disulfide isomerase (PDI) is overexpressed in glioblastoma, the most aggressive form of brain cancer, and folds nascent proteins responsible for the progression and spread of the disease. Herein we describe a novel nanomolar PDI inhibitor, pyrimidotriazinedione 35G8, that is toxic in a panel of human glioblastoma cell lines. We performed a medium‐throughput 20 000‐compound screen of a diverse

  • Toxoflavins and Deazaflavins as the First Reported Selective Small Molecule Inhibitors of Tyrosyl-DNA Phosphodiesterase II

    The recently discovered enzyme tyrosyl-DNA phosphodiesterase 2 (TDP2) has been implicated in the topoisomerase-mediated repair of DNA damage. In the clinical setting, it has been hypothesized that TDP2 may mediate drug resistance to topoisomerase II (topo II) inhibition by etoposide. Therefore, selective pharmacological inhibition of TDP2 is proposed as a novel approach to overcome intrinsic or acquired resistance to topo II-targeted drug therapy. Following a high-throughput screening (HTS) campaign, toxoflavins and deazaflavins were identified as the first reported sub-micromolar and selective inhibitors of this enzyme. Toxoflavin derivatives appeared to exhibit a clear structure-activity relationship (SAP.) for TDP2 enzymatic inhibition. However, we observed a key redox liability of this series, and this, alongside early in vitro drug metabolism and pharmacokinetics (DMPK) issues, precluded further exploration. The deazaflavins were developed from a singleton HTS hit. This series showed distinct SAR and did not display redox activity; however low cell permeability proved to be a challenge.
