3-Chlorotyrosine a specific marker of myeloperoxidase-catalyzed oxidation is markedly elevated in low-density lipoprotein isolated from human atherosclerotic intima. In particular myeloperoxidase halogenates tyrosine residues in plasma proteins and generates 3-chlorotyrosine (CY).

N-Aminofluorescein is a highly selective and sensitive fluorescent probe for Cu2+ and can be used to detect Cu2+ in biological systems (λex/em=495/516 nm).

(±)-Jasmonic acid methyl ester induces the synthesis of proteinase inhibitors in plant leaves. In cancer cells it suppresses proliferation and induces apoptosis.
