Synthetic Strategies to Derivatizable Triphenylamines Displaying High Two-Photon Absorption
摘要:
[Graphics]A versatile synthetic strategy to access a set of highly fluorescent g-conjugated triphenylamines bearing a functional linker at various positions on one phenyl ring is described. These compounds were designed for large two-photon absorption (2PA) and in particular for labeling of biomolecules. The monoderivatized trisformylated or trisiodinated intermediates described herein allow introduction of a large variety of electron-withdrawing groups required for large 2PA as well as a panel of chemical functions suitable for coupling to biomolecules. The monoderivatized three-branched compounds and in particular the benzothiazole JP-3Bz) series show remarkable linear (high extinction coefficients and high quantum yield) and nonlinear (high 2-photon cross sections) optical properties. Interestingly the presence of functional side chains does not disturb the two-photon absorption. Finally, monoderivatized two-branched derivatives also appear to be valuable candidates. Altogether the good optical properties of the new derivatizable pi-conjugated TPA combined with their small size and their compatibility with bioconjugation protocols suggest that they represent a new chemical class of labels potentially applicable for the tracking of biomolecules using two-photon scanning microscopy.

[EN] The invention relates to novel triphenylamine derivatives for use as fluorophores, in particular for two-photon microscopy in biology. It also relates to compositions containing these derivatives, to the use of these compositions and also the derivatives themselves for labelling biological molecules (or 'biomolecules') such as nucleic acids, oligonucleotides, proteins, polypeptides, plasmids, etc., with a view to observing them in particular by two-photon microscopy, and to biomolecules labelled with said derivatives. Applications: biological and medical imaging (fundamental research for the structural or functional study of biological systems, applied research for clinical or therapeutic purposes, diagnosis and medical screening, etc.). [FR] L'invention se rapporte à de nouveaux dérivés de la triphénylamine utiles comme fluorophores, notamment pour la microscopie biphotonique en biologie. Elle se rapporte également à des compositions contenant ces dérivés, à l'utilisation de ces compositions ainsi que des dérivés eux-mêmes pour le marquage de molécules biologiques (ou "biomolécules") telles que les acides nucléiques, les oligonucléotides, les protéines, les polypeptides, les plasmides, etc, en vue de leur observation notamment par microscopie biphotonique, et à des biomolécules marquées par lesdits dérivés. Applications: imagerie biologique et médicale (recherche fondamentale pour l'étude structurelle ou fonctionnelle des systèmes biologiques, recherche appliquée à visée clinique ou thérapeutique, diagnostic et dépistage médical,...).
