MCE 国际站:3-Methyltoxoflavin
产品活性:3-Methyltoxoflavin 是蛋白质二硫键异构酶 (PDI) 的有效抑制剂,其 IC50 值为 170 nM。
研究领域:Cell Cycle/DNA Damage | Metabolic Enzyme/Protease
作用靶点:PDI
In Vitro: 3-Methyltoxoflavin is a potent Protein disulfide isomerase (PDI) inhibitor, with an IC50 of 170 nM. 3-Methyltoxoflavin is toxic in a panel of human glioblastoma cell lines. From the screen, 3-Methyltoxoflavin emerges as the most cytotoxic inhibitor of PDI. Bromouridine labeling and sequencing (Bru-seq) of nascent RNA reveals that 3-Methyltoxoflavin induces Nrf2 antioxidant response, ER stress response, and autophagy. Specifically, 3-Methyltoxoflavin upregulates heme oxygenase 1 and SLC7A11 transcription and protein expression and represses PDI target genes such as TXNIP and EGR1. Interestingly, 3-Methyltoxoflavin-induced cell death does not proceed via apoptosis or necrosis, but by a mixture of autophagy and ferroptosis.
