Cilostamide is a selective inhibitor of type III phosphodiesterase (PDE3).

Coumarin is a secondary phytochemical isolated and purified from the herbs of Melilotus officinalis with hepatotoxic and carcinogenic properties.

7-Amino-4-methylcoumarin is a natural product isolated and purified from an endophytic Xylaria fungal species and exhibited strong antibacterial and antifungal activities in vitro against Aspergillus, Candida, Escherichia, Staphylococcus, Salmonella and Vibrio species, among others. It is also a reagent employed in the preparation of fluorogenic AMC-based substrates for the detection of proteolytic enzyme activity. AMC has been utilized as a fluorescent probe to analyze glycoproteins' monosaccharides and N-linked oligosaccharides via chromatography and has been used as a laser dye.

Ethyl 3-coumarincarboxylate is a coumarin derivative. Ethyl 3-coumarincarboxylate can be used as a pseudo-template to give a molecularly imprinted polymer (MIP) that has a fairly specific recognition capability for aflatoxins[1].

7-Amino-4-methyl-3-coumarinylacetic acid (AMCA) is fluorescent protein labeling agent.1 It contains an N-hydroxysuccinimide ester that reacts with lysine residues to form photostable amide links. Upon activation with UV light, AMCA displays emission maxima of 400-460 nm. It has commonly been used in multiplex immunophenotyping applications.

Coumarin 6 是一种荧光染料，常用于生物成像和细胞标记(λexc=450 nm，λem=505 nm)。Coumarin 6 能够标记细胞膜、细胞器或其他生物分子，用于细胞生物学和分子生物学实验中进行观察和分析。
