Ruxoprubart (NM8074) is an inhibitor of complement factor B (Bb subunit). Ruxoprubart selectively binds to active Bb to inhibit the alternative complement pathway without affecting the classical complement pathway. By blocking the activities of AP C3 and C5 convertases, Ruxoprubart effectively inhibits red blood cell hemolysis and reduces C3b deposition, thereby preventing intravascular and extravascular hemolysis. Ruxoprubart can be used in research related to paroxysmal nocturnal hemoglobinuria, atypical hemolytic uremic syndrome, C3 glomerulopathy, and IgA nephropathy .

Bathophenanthrolinedisulfonic acid disodium is an iron ion chelator that serves as a colorimetric reagent for iron ion detection. Bathophenanthrolinedisulfonic acid disodium forms stable, strong complexes with Fe 2+ and Fe 3+, and each complex exhibits reversible redox behavior. Bathophenanthrolinedisulfonic acid disodium can act as a ligand to form water-soluble ruthenium catalysts, which promote the hydrogenation of the ketone group in levulinic acid to produce γ-valerolactone. When Bathophenanthrolinedisulfonic acid disodium and its iron complex are incorporated into a polymer-modified electrode, rapid color change from red to transparent occurs during potential cycling .

Synonyms: mPEG5000-Maleimide
mPEG5000-Mal (mPEG5000-Maleimide) is a PEG-derived selective covalent binding agent for sulfhydryl groups (RSGs), which can form irreversible thioether bonds with sulfhydryl groups under near-neutral conditions via the maleimide group. The mechanism of action of mPEG5000-Mal can be divided into two categories: firstly, as an enzyme modifier, it binds to target proteins through hydrophobic interactions, hydrogen bonds, and van der Waals forces, altering the protein's secondary structure; secondly, as a nanoparticle surface modifier, it covalently binds to sulfhydryl groups on the surface of red blood cells, changing the surface properties and morphology of the red blood cells, leading to their phagocytosis by macrophages of the reticuloendothelial system. mPEG5000-Mal can react with free cysteine in proteins, increasing the apparent molecular weight of the modified protein by 10-15 kDa for detection purposes. mPEG5000-Mal can enhance the thermal stability and catalytic activity of enzymes, and improve the macrophage targeting of nanoparticles, enabling targeted drug delivery. mPEG5000-Mal can be applied in enzyme engineering research in the food industry and in oncology, assisting radiotherapy by inhibiting tumor-associated macrophage infiltration and enhancing anti-tumor immune responses .

DC271 is a RAR agonist and synthetic retinoid that binds to the retinoid-binding site of cellular retinoic acid-binding protein II (CRBP-II). DC271 exhibits solvatochromic fluorescence properties: it produces intense blue-shifted emission in nonpolar environments and weak red-shifted emission in polar environments, and its severe fluorescence quenching in aqueous solutions can be reversed by embedding in the hydrophobic retinoid-binding protein pocket. DC271 enables direct detection of the binding between unlabeled compounds and related retinoid-binding proteins via fluorescence competition assays (Ex/Em = 355 nm/460 nm) .

HMBI is a fluorescent probe that enables dual-color visualization of both the nucleus and mitochondria and monitors apoptosis. HMBI emits green fluorescence in the nucleus with Ex/Em=405/510-560 nm, and red fluorescence in mitochondria with Ex/Em=543/560-660 nm. The localization and emission properties of HMBI depend on subcellular pH and mitochondrial membrane potential. HMBI can serve as a feed additive for in vitro rumen fermentation; it is partially degraded, absorbed or converted into HMB by microorganisms in the system, so as to support microbial protein synthesis, alter the concentration of rumen metabolites and adjust the composition of bacterial communities .
