BAY 11-7082<\/u><\/a>\u00a0(BAY 11-7821, M2040, AbMole) \u00a0is a widely used NF-\u03baB inhibitor applied in research on inflammatory responses, cancer, and immune regulation. BAY 11-7082 (CAS No.: 19542-67-7) selectively inhibits I\u03baB\u03b1 phosphorylation in the NF-\u03baB pathway, thereby blocking I\u03baB\u03b1 degradation and NF-\u03baB nuclear translocation, ultimately suppressing the transcription of NF-\u03baB-dependent genes[1]<\/sup>. In addition to this classical pathway, BAY 11-7082 also inhibits the ubiquitin-specific proteases USP7 and USP21 (IC50: 0.19 \u03bcM and 0.96 \u03bcM, respectively) and interferes with ubiquitin-conjugating enzyme E2 activity. In RAS-mutant tumor cells, BAY 11-7082 significantly suppresses the growth of NRAS-, KRAS-, and HRAS-mutant tumor cells, an effect validated both in vitro and in mouse xenograft models[1]<\/sup>. Its molecular mechanisms include inhibition of the PI3K-AKT signaling pathway, activation of apoptotic pathways, and downregulation of multiple pro-survival genes [1]<\/sup>. In liver fibrosis research, BAY 11-7082 is used to inhibit activated hepatic stellate cells [2]<\/sup>. BAY 11-7082 also exhibits multiple protective effects in animal models of neurological disorders. For example, it inhibits TNF-\u03b1-induced astrocyte dedifferentiation via the NF-\u03baB-Nanog-CD44\/Musashi-1 signaling axis[3]<\/sup>; alleviates neuropathy\u00a0<\/strong>and improves mitochondrial function in diabetic mouse models[4]<\/sup>; and in a postnatal rat model, it inhibits sevoflurane-induced hippocampal pyroptosis and neuroinflammation, preserving synaptic integrity and improving neurocognitive function[5]<\/sup>. In bone metabolism research, BAY 11-7082 is used to validate the regulatory role of the NF-\u03baB pathway in osteogenic differentiation[6].<\/sup>\u00a0Thus, BAY 11-7082 is not only an essential tool compound for studying the NF-\u03baB pathway but also demonstrates strong application potential in animal models of cancer, neurodegenerative diseases, fibrotic diseases, and metabolic diseases.<\/p>\n\n\n\n

Case Study<\/strong><\/strong><\/p>\n\n\n\n

J Inflamm Res. 2021 Mar 17;14:917-928.<\/strong><\/strong><\/p>\n\n\n\n

Researchers from the State Key Laboratory of Bioelectronics at Southeast University developed a high-throughput visual screening platform for NF-\u03baB inhibitors using three gene-edited tumor cell lines. Using TALEN and CRISPR technology, they edited five NF-\u03baB family genes (RELA, RELB, CREL, NF-\u03baB1, NF-\u03baB2) in three cell lines (293T, HepG2, and PANC1) to enable ZsGreen fusion expression. BAY 11-7082<\/u><\/a> (M2040, BAY 11-7821) provided by AbMole was used as an NF-\u03baB inhibitor to validate cellular responsiveness to NF-\u03baB inhibition. In 2014, two inhibitors from AbMole were used in <\/strong>in vivo<\/em><\/strong><\/em><\/strong> studies by the Spanish National Center for Cardiovascular Research (CNIC) and Columbia University, leading to <\/strong>publications <\/strong><\/u><\/strong><\/a>in <\/strong>Nature <\/em><\/strong><\/em><\/strong>and <\/strong>Nature Medicine<\/em><\/strong><\/em><\/strong>.<\/strong><\/strong><\/p>\n\n\n\n
