Chlorobenzothiazolinone inhibits recombinant human chymase using bis(succinoyl-L-alanyl-L-prolyl-L-phenylalanylamide) as substrate after 1 hr by fluorescence assay with activity value of 90 μM.

Acridine is a classic fluorescent pH indicator that combines stability and fluorescence properties. Its tricyclic conjugated molecular structure can achieve pH response. In different pH environments, Acridine molecules undergo protonation or deprotonation transformations, and this structural change significantly alters their fluorescence properties.

Tetracycline hydrochloride (NCI-c55561) is the hydrochloride salt of the tetracycline, a broad-spectrum naphthacene antibiotic produced semisynthetically from chlortetracycline, an antibiotic isolated from the bacterium Streptomyces aureofaciens. In bacteria, tetracycline blocks binding of aminoacyl-tRNA to the mRNA-ribosome complex, thereby inhibiting protein synthesis and bacterial cell growth. Because naturally, fluorescing tetracycline binds to a newly formed bone at the bone/osteoid interface, tetracycline-labeling of bone and fluorescence microscopy may be used to perform bone histomorphometry.

Anthracene is a polycyclic aromatic hydrocarbon (PAH) consisting of three fused benzene rings that presents as a colorless, solid, crystalline substance derived primarily from coal tar, known for its characteristic blue fluorescence under ultraviolet light and its extensive use as a fundamental raw material for producing anthraquinone dyes, synthetic fibers, and various other organic compounds. While Anthracene serves as a component in some wood preservatives and asphalt products, Anthracene is also a recognized environmental pollutant and is classified as a potential occupational carcinogen by some regulatory bodies.
