Mca-PLAC(p-OMeBz)-WAR(Dpa)-NH2 is a fluorogenic substrate for matrix metalloproteinase-14 (MMP-14). Upon cleavage by MMP-14, 7-methoxycoumarin-4-acetyl (Mca) is released and its fluorescence can be used to quantify MMP activity. Mca displays excitation/emission maxima of 328/420 nm, respectively.

Arg-Val-(Nle-p-nitro)-Phe-Glu-Ala-Nle-NH2 is a fluorogenic substrate used for assessing HIV-1 protease activity [1].

Mca-P-Cha-G-Nva-HA-Dap(DNP)-NH2 is a fluorogenic substrate used for quantifying the activity of matrix metalloproteinase-1 (MMP-1), MMP-3, and MMP-26, thus facilitating the measurement of these enzymes' activity [1] [2].

2-N-Ethyl-p-(6-methoxybenzothiazol-2-yl)azoanilinoethanol serves as a versatile dye utilized across various domains. Dyes play a crucial role in biological experiments, enabling researchers to investigate and discern cell structures, monitor biomolecules, assess cellular functions, differentiate cell types, examine tissue pathology, and track microorganisms. Their utility extends beyond fundamental scientific research to include a broad spectrum of clinical diagnostics. Additionally, dyes are integral to conventional applications like textile dyeing and in newer areas such as functional textile processing, food pigments, and dye-sensitized solar cells.

Mca-AVLQSGFR-K(Dnp)-K-NH2 serves as a fluorogenic substrate specifically designed for the main protease (Mpro) of the severe acute respiratory syndrome coronavirus (SARS-CoV), also referred to as 3C-like protease (3CLpro). This substrate, upon enzymatic cleavage by SARS-CoV Mpro, liberates 7-methoxycoumarin-4-acetyl (Mca) which emits fluorescence. This fluorescence emission, with excitation/emission peaks at 328/420 nm respectively, facilitates the quantification of SARS-CoV Mpro's catalytic activity.

Mca-SEVNLDAEFR-K(Dnp)-RR-NH2 is a fluorogenic substrate designed for the quantification of β-secretase (BACE) activity. When cleaved by BACE, it liberates 7-methoxycoumarin-4-acetyl (Mca), a compound whose fluorescence, with excitation and emission peaks at 328 nm and 420 nm respectively, serves as a measurable indicator of BACE enzymatic action.

Mca-SEVNLDAEFK(Dnp)-NH2 is a fluorogenic substrate featuring a 7-methoxycoumarin moiety whose fluorescence is quenched by the adjacent 2,4-dinitrophenyl group through resonance energy transfer. This compound serves as a probe for assessing peptidase activity; enzymatic cleavage of the amide bond separating the fluorophore and quencher results in increased fluorescence. It is particularly useful for quantifying the activity of BACE-1 [1].

Mca-PLGL-Dpa-AR-NH2 is a fluorescent peptide MMP substrate [1] .

Mca-KPLGL-Dap(Dnp)-AR-NH2 serves as a fluorogenic substrate specifically designed for matrix metalloproteinases (MMPs). This compound facilitates the quantification of MMP activity by releasing 7-methoxycoumarin-4-acetyl (Mca) upon enzymatic cleavage by MMPs, which exhibits fluorescence with excitation and emission maxima at 328 nm and 420 nm, respectively.

Mca-Lys-Pro-Leu-Gly-Leu-Dap(Dnp)-Ala-Arg-NH2 (FS-6) is a quenched, fluorescent MMP peptide substrate designed for real-time quantification of MMP enzymatic activity. As an extended variant of the MMP substrate (FS-1), it demonstrates increased specificity against collagenases (MMP-1, MMP-8, MMP-13) and MT1-MMP, with higher specificity constants (Ex Em=325 nm 400 nm).
