NIR-BG2 is a fluorescent indicator targeting senescence-associated β-galactosidase (SA-β-Gal). NIR-BG2 contains a hemicyanine fluorophore caged by SA-β-Gal; cleavage of its β-galactosyl group by SA-β-Gal generates an electrophilic quinone methide, which can form covalent bonds with adjacent proteins to achieve long-term signal retention. NIR-BG2 activates a near-infrared fluorescent signal upon recognition of SA-β-Gal. NIR-BG2 can be used for non-invasive in vivo imaging of cellular senescence in mouse xenograft models. The excitation/emission wavelengths are 675/708 nm .

Inflammation/Immunology

Biotin-(Oaa)3-epoxomicin is a biotin-labeled form of Epoxomicin (HY-13821), prepared by conjugating Epoxomicin with biotin via three hydrophilic oxaacetyl amino acid (Oaa) linkers. Biotin-(Oaa)3-epoxomicin is primarily used in proteomic studies for the capture, identification and target validation of proteasome complexes, to determine the intracellular targets of epoxomicin. Epoxomicin acts as a proteasome inhibitor and NF-κB inhibitor, which effectively blocks inflammatory responses in mouse ear edema assays. It inhibits proteasome activity via covalent binding to catalytic subunits including LMP7, X, MECL1 and Z, with the strongest inhibitory effect on chymotrypsin-like activity, and does not interfere with non-proteasomal proteases such as trypsin and papain .
