STAT3/NF-κB-IN-3 is an orally active STAT3/NF-κB inhibitor with anti-inflammatory and antioxidant activities, which specifically blocks the phosphorylation of NF-κB and STAT3 proteins. STAT3/NF-κB-IN-3 downregulates the expression of iNOS and NOX-2 in macrophages, reduces intracellular levels of ROS and MDA, and upregulates the expression of antioxidant genes at the same time. In a mouse model of acute liver failure induced by LPS/D-GalN, STAT3/NF-κB-IN-3 alleviates liver necrosis and inflammatory cell infiltration, and reduces the release of pro-inflammatory cytokines such as IL-6 and IL-12 via the TLR4 pathway. STAT3/NF-κB-IN-3 can be used in studies related to acute liver failure .

BG-PEG-NH2 (SNAP-PEG-NH2) is an amino-terminal fluorescent probe building block and a precursor for site-specific labeling of SNAP-tag fusion proteins. BG-PEG-NH2 undergoes one-step coupling with activated carboxyl esters to form customized SNAP-tag substrates, which covalently bind to SNAP tags via a thioether bond formed at the Cys145 site. After coupling with a caged carboxyfluorescein, BG-PEG-NH2 forms a probe with Ex/Em = 500/524 nm following ultraviolet uncaging. Coupling of BG-PEG-NH2 with SeTau-647-NHS enables visualization of GPCR signal transduction.
