Definitions
- the present invention relates to novel triphenylamine derivatives useful as fluorophores in biology, especially for biphotonic microscopy.
- compositions comprising these derivatives, to the use of these compositions as well as derivatives themselves for the labeling of biological molecules (or "biomolecules") of the nucleic acid, oligonucleotide, protein, polypeptide type, plasmids, etc., for their observation in particular by two-photon microscopy, and to biomolecules labeled with said derivatives.
- biological molecules or "biomolecules”
- biomolecules of the nucleic acid, oligonucleotide, protein, polypeptide type, plasmids, etc.
- Fluorescence microscopy is a tool commonly used by biologists because of its ability to detect, quantify and provide images of both the natural components of biological systems and of elements unrelated to these systems.
- fluorophores have the particularity to bind specifically to biomolecules: for example, 4, 6-diaminido-2-phenylindole (or DAPI), which fluoresces in blue when excited by a violet light, is fixed specifically on DNA.
- Other fluorophores do not have this ability and need to be grafted on a molecule specific to that which one seeks to detect. This is the case, for example, with rhodamine and fluorescein that can be used either to detect an antigen, in which case they are grafted on an antibody specific for this antigen, or as tracers of cell lineage, in which case they are transplanted onto a molecule with good stability in biological media such as dextran.
- fluorescence microscopy has grown considerably thanks to the arrival of new optical technologies including confocal laser scanning microscopy and, more recently, two-photon excitation fluorescence microscopy, also called biphotonic microscopy.
- biphotonic microscopy is, of all fluorescence microscopy techniques, the one that develops most in the field of biology. Its principle is to simultaneously bring two photons of energy identical to a compound to produce an excitation equivalent to that which would have driven a single photon of high energy. For the process to be effective, it is necessary for the photons to reach the compound in a very short time interval, of about 10-15 seconds, which has been made possible by the use of laser light sources producing pulses. ultra-brief and very intense.
- Two-photon microscopy has many advantages. Indeed, the processes of photobleaching and phototoxicity, often limiting in single-photon microscopy, are here limited to the maximum. In addition, excitation photons, which are typically located in the near infrared
- excitation radiation is less destructive for biological samples and penetrates deeper into tissue up to about 0.5 mm.
- two-photon microscopy has a spatial resolution as good as that of confocal laser scanning microscopy, that is to say of the order of a micrometer.
- fluorophores used in two-photon microscopy are the same as those used in single-photon microscopy.
- these fluorophores have poor two-photon fluorescence properties, especially in terms of absorption cross-section, which limits the scope of applications of bi-photon microscopy in biology.
- the inventors have therefore set themselves the goal of developing fluorophores that are perfectly adapted to the use of two-photon fluorescence in the field of biology.
