摘要:
The present invention relates to novel fluorinated 3,6-diaminoxanthene compounds derived from the basic structural formula (I) and to their uses as photostable fluorescent dyes, e.g. for immunostainings and spectroscopic and microscopic applications, in particular in conventional microscopy, stimulated emission depletion (STED) reversible saturable optically linear fluorescent transitions (RESOLFT) microscopy, and fluorescence correlation spectroscopy. The claimed compounds are also useful as molecular probes in various spectroscopic applications.

The invention relates to novel fluorescent dyes with phosphorylated hydroxymethyl groups, a method for preparing the same as well as to their use in imaging techniques. The fluorescent dyes are coumarin, rhodamine or BODIPY dyes having of one of the following general formulae I-III: wherein W=OP(O)Y1Y2 or P(O)Y1Y2, where Y1 and Y2 independently denote any of the following residues: OH, O(−), ORa and ORb, NHRa and NHRb, NRaRb and NRcRd, ORa and NHRb, ORa and NRbRc, NHRa and NRbRc; and any salt thereof.
摘要:
The present invention relates to novel photoactivable rhodamine or carbopyronine derivatives of the following general formulae G1-G4 (I), G1: A1 = O, A2 = N, A3 = C; G2: A1 = S, A2 = N, A3 = C; G3: A1 = O, A2 = O, A3 = N; G4: A1 = S, A2 = O, A3 = N; comprising UV light absorbing chromophores which after photolysis by irradiation at 254-490 nm (preferably at 375-420 nm) generate fluorescent rhodamine or carbopyronine derivatives and small non-toxic fragments such as N 2 or N 2 O. The invention also relates to methods for preparing such compounds and to the use of these compounds for optical microscopy and imaging techniques.
