Nitrocefin is a highly activated, chromogenic cephalosporin derivative. Nitrocefin is a chromogenic β-lactamase substrate. Nitrocefin undergoes a distinctive color change from yellow to red as the amide bond in the β-lactam ring is hydrolyzed by β-lactamase. Nitrocefin is used in competitive inhibition studies in developmental work on β-lactamase-resistant antibiotics .

Chlorophenol red-β-D-galactopyranoside (CPRG) is an efficient and sensitive chromogenic substrate for β-galactosidase (HY-P2869), widely used in colorimetric assays. Chlorophenol red-β-D-galactopyranoside itself appears pale yellow. When it is specifically hydrolyzed by β-galactosidase, it releases chlorophenol red. The released chlorophenol red turns purple-red under alkaline or neutral pH conditions. This color change from yellow to red can be quantitatively detected at wavelengths of 540-572 nm using visible spectrophotometry .

CAS No.: 2635-84-9
4-Nitrophenyl butyrate consists of butyric acid chains esterified with 4-nitrophenol groups, thus giving it a yellow color. This compound is commonly used as a substrate in enzyme assays to measure esterase and lipase activity. When these enzymes cleave the ester bond, the nitrophenol group is released and the color changes from yellow to orange. Thus, the rate of color change can be used to determine enzyme activity. In addition, 4-Nitrophenyl butyrate can also be used as organic synthesis reagent and dye intermediate.

3-Methyl-2-nitrophenol is a UDP-glucuronyltransferase (EC 2.4.1.17) acceptor substrate that can be confirmed to undergo glucuronidation catalyzed by the enzyme to form a glucuronide conjugate. 3-Methyl-2-nitrophenol functions as a substrate for conjugation, with glucuronidation forming a glucuronide conjugate that eliminates the parent compound’s characteristic yellow color. 3-Methyl-2-nitrophenol has higher lipid solubility that contributes to high glucuronidation conversion rate, and exhibits lower absorbance at 340 nm to act as a less interfering substrate for the NADH-NAD +-linked UDP-glucuronyltransferase assay .

HMRef-αMan is a substrate-based green fluorescent probe (Ex/Em=465 nm/515 nm) targeting MAN2C1 (α-mannosidase). HMRef-αMan can be specifically cleaved by MAN2C1 to generate a highly fluorescent product, which thus gets activated to produce green fluorescence in malignant breast tissues, benign lesions and living cancer cells. The signal intensity of HMRef-αMan is directly correlated with MAN2C1 activity, and it can effectively detect tiny breast cancer lesions with a diameter of less than 1 mm. When used in combination with the red-emitting γ-glutamyl transpeptidase (GGT) probe gGlu-2OMe SiR600 (HY-D3188), HMRef-αMan enables precise optical differentiation of breast tissue types via a dual-color imaging strategy. HMRef-αMan has been widely used in the research of breast diseases such as breast cancer, fibroadenoma, phyllodes tumor and various types of papilloma .
