hCYP3A4 Fluorogenic substrate 1, a phthalimide derivative, exhibits low activity against COX.

MMTr-Cy3-OH is a Cy3-derived dye. The MMTr protecting group ensures stability of the intermediate product, while the hydroxyl group facilitates subsequent reactions. Cy3 (Sulfo-Cyanine 3) is an amine-reactive cyanine orange dye with excitation/emission wavelengths of 550/570 nm, commonly employed for fluorescent labelling of proteins and nucleic acids.

Lumogallion (4-Chloro-3-(2,4-dihydroxyphenylazo)-2-hydroxybenzene-1-sulfonic acid) is an azo reagent used in the determination of metal ions, such as the research of V, Fe, and Al.

cis-Parinaric acid is a naturally occurring polyunsaturated fatty acid containing an unusual conjugated (Z,E,E,Z) tetraene. This chromophore provides for a natural fluorescence at 432 nm with an excitation wavelength at 320 nm. cis-Parinaric acid occurs naturally in the seeds of the Makita tree, a tropical rainforest tree indigenous to Fiji. Makita seeds are inedible, and this toxicity may be due at least in part to the unstable conjugated fatty acids, including cis-parinaric acid, contained within the seed. cis-Parinaric acid has been used for the measurement of phospholipase activity, lipase activity, and as an indicator of lipid peroxidation.[1][2][3][4]

STY-BODIPY (Styrene-BODIPY) is a styrene-conjugated fluorescent probe enabling calculation of radical trapping antioxidant (RTA) activity by monitoring absorbance loss at 571 nm.

bis-ANS is a high-affinity non-covalent extrinsic fluorescent dye used to analyze protein conformation.[1] Its predominant interaction with proteins is through its hydrophobic phenyl and naphthyl rings.[2] bis-ANS has an excitation maxima of 390 nm.[3] It has an emission maximum of 523 nm when free in solution but undergoes a blue shift with an increase in fluorescence intensity when bound to protein; for example, when bound to intestinal fatty acid binding protein (FAPB2) it has emission maxima of 484-496 nm. bis-ANS has been used to label mechanically damaged neurons in acute brain slices.4 It also potently inhibits microtubule assembly.[5],[6]

Biotin-11-dUTP [tetra(triethylammonium) salt] [(2S,3S,4R,5R,6R)-5-(2,4-dioxopyrimidin-1-yl)-4-hydroxy-6-(hydroxymethyl)-2-[(3aR,4S,6R,6aS)-2-oxohexahydro-2H-thieno[3,4-d]imidazol-4-yl]-tetrahydro-2H-furo[3,2-d][1,3,2]dioxaphosphorin-3-yl]phosphonate] is used as a fluorescent substitute for dTTP.

4-Methylumbelliferyl phosphate disodium (4-MUP), an anionic organophosphate, serves as a fluorogenic substrate for acid and alkaline phosphatases. Additionally, this compound acts as a simulant for nerve agents [1] [2] [3].

Bromocresol Green, a triphenylmethane dye, serves primarily as a pH indicator transitioning from yellow (λmax=435 nm, protonated form) at pH 4.15 to blue (λmax=615 nm, deprotonated form) in alkaline environments. Utilized in biochemical analysis, it quantifies serum protein and albumin, assesses creatinine concentration, and evaluates cell viability [1] [2] [3] [4]. The dye exhibits a bio-based, yellow-green to blue-green hue.

Dibenzylfluorescein (DBF), a fluorogenic probe (Fluorescent dye), serves as a substrate for various cytochrome P450 (CYP) isoforms, such as CYP3A4, CYP2C8, CYP2C9, CYP2C19, and aromatase (CYP19). It is commonly utilized at its K_m value range of 0.87-1.9 µM (Ex=485nm, Em=535nm) to monitor alterations in CYP enzymatic activity attributable to pharmaceutical interventions or pathophysiological conditions [1] [2] [3] [4].

4-(2-Carboxyphenyl)-7-diethylamino-2-(7-diethylamino-2-oxochroman-3-yl)-chromylium perchlorate is an organic fluorescent dye that features a carboxyl functional group, with an excitation wavelength (λ ex) of approximately 650 nm and an emission wavelength (λ em) of around 690 nm [1].

4-Amino-3-hydroxynaphthalene-1-sulfonic acid serves as a fluorescent dye and is employed in the formation of polypyrrole (PPy) conducting films with pyrrole for use in electrochemie [1] [2].

Compound 3, formally known as ethyl benzo[6,7]-4-oxo-4H-quinolizine-3-carboxlate, serves as a Mg 2+ selective fluorescent indicator [1].

CelRed nucleic acid gel stain 10,000× concentrate in water is a fluorescent dye used for nucleic acid staining, suitable for staining and detecting dsDNA, ssDNA, or RNA in agarose gels or polyacrylamide gels.

1) Non-toxicity: belong to flower-stem dye, easy to biodegrade, no carcinogenic toxicity. 2) High sensitivity: at least 100pg ssDNA or RNA can be detected, which is 25 ~ 100 times higher than EB staining. 3) High SIGNal-to-noise ratio: the sample fluorescence signal is strong, while the background signal is low. 4) Simple operation: like EB, the dye does not degrade in the prefabricated gel and electrophoresis process;The dyeing process after electrophoresis takes only 30 minutes without decoloring or washing, and can be observed directly with ultraviolet gel transmission or visible light transmission.
