  • Fluorogenic/fluorescent probes derivative from sulfoxanthene, and use thereof
    Patent number: 9528990
    Abstract: The invention relates to fluorescent/fluorogenic probes of formula (I?) or (II?): wherein Z is chosen between: —NH2 and —OH, or in the fluorescence quencher group consisting of: —NO2; —N?N—R1; R1 being any organic group that does not obscure the corresponding azo bond; —NHCO-Pept.; Pept. being a peptide residue or any organic group that does not obscure the corresponding amide bond; —O-Glyc.; Glyc. being a oligoglycoside residue that does not obscure the corresponding glycosidic bond; —O—C(O)—R2; —O—P(O)(OR2)(OR2?) and —O—S(O)2—R2; R2 and R2? being independently a hydrogen atom or an organic group that does not obscure the corresponding ester bond; and ?Ra, Rb, Rc, Rd and Re being independently a hydrogen atom or any organic group that does not obscure the corresponding arylether bond so as not to prevent its possible cleavage by a myeloperoxidase activity.
