一般說明

Cyclohexylaminoethanesulfonic acid (CHES) is a buffering agent. Its structure contains a hydrophilic taurine (2-aminoethanesulfonic acid) moiety and a hydrophobic cyclohexyl group. CHES binds to the active site of several enzymes and inhibits substrate binding and enzymatic activity. Therefore, CHES may be used as a scaffold for new drug development for regulating enzyme activity.[1]

應用

2-(Cyclohexylamino)ethanesulfonic acid (CHES) has been used in the preparation of dimethyl trisulfide- polysorbate 80 (DMTS-PS80) formulation.[2]

其他說明

Buffer for studying pH-dependent processes in enzymology; Has a high affinity for the iodoacetate binding site of liver alcohol dehydrogenase.

Stability Characterization of a Polysorbate 80-Dimethyl Trisulfide Formulation, a Cyanide Antidote Candidate.

Craig M Bartling et al.

Drugs in R&D, 16(1), 109-127 (2016-02-11)

Novel cyanide countermeasures are needed for cases of a mass-exposure cyanide emergency. A lead candidate compound is dimethyl trisulfide (DMTS), which acts as a sulfur donor for rhodanese, thereby assisting the conversion of cyanide into thiocyanate. DMTS is a safe

Crystal structure of the catalytic domain of Clostridium perfringens neuraminidase in complex with a non-carbohydrate-based inhibitor, 2-(cyclohexylamino)ethanesulfonic acid.

Youngjin Lee et al.

Biochemical and biophysical research communications, 486(2), 470-475 (2017-03-21)

Anti-bacterial and anti-viral neuraminidase agents inhibit neuraminidase activity catalyzing the hydrolysis of terminal N-acetylneuraminic acid (Neu5Ac) from glycoconjugates and help to prevent the host pathogenesis that lead to fatal infectious diseases including influenza, bacteremia, sepsis, and cholera. Emerging antibiotic and

Affinity labelling of liver alcohol dehydrogenase. Effects of pH and buffers on affinity labelling with iodoacetic acid and (R, S)-2-bromo-3-(5-imidazolyl)propionic acid.

C Syvertsen et al.

European journal of biochemistry, 117(1), 165-170 (1981-06-01)

Both iodoacetic acid and (R,S)-2-bromo-3-(5-imidazolyl)propionic acid (BrImPpOH) react with liver alcohol dehydrogenase in an affinity labelling mechanism between pH 6.1 and 10.5. The buffer-independent dissociation constants and the first-order rate constants have been determined as a function of pH. With

Preparation and electrophoretic separation of Bodipy-Fl-labeled glycosphingolipids.

Scott A Sarver et al.

Journal of chromatography. A, 1229, 268-273 (2012-02-11)

Several glycosphingolipids were labeled with the fluorphore Bodipy-Fl and analyzed using capillary electrophoresis with laser-induced fluorescence detection. GM1-, LacCer-, and Cer-Bodipy-Fl were prepared through acylation using the N-hydroxysuccinimide ester of Bodipy-Fl. Several other glycosphingolipids including GT1a-, GD1a-, GM2-, GM3-, GD3-
