摘要:
The invention relates to compounds of formula (I) : the groups A and B represent independently from each other -CH=CH-, or -C≡C-, the terms t, u, v, w represent, independently from each other, values ranging from 0 to 9, the groups Y 1 and Y 2 can represent independently from each other an alkyl group (linear, branched or substituted) carrying from 1 to 9 carbon atoms, the groups Z 1 , Z 2 , Z 3 , and Z 4 can represent independently from each other a chemically reactive group W, such as OH, NH 2 , SH, the groups Z 5 and Z 6 represent independently from each other a hydrogen atom, silica nanoparticles functionalized by these compounds, and their use as drugs.
摘要:
The invention relates to nanovectors of formula (I) that can be used simultaneously for the targeting, imaging and treatment, by means of photodynamic therapy, of cancer cells, and to biodegradable silicon nanoparticles containing a variety of photosensitizing molecules, in particular porphyrins, capable of targeting diseased cells and inducing cell death by means of excitation in the near-infrared region (> 600 nm) in monophotonic and biphotonic modes. According to the invention, in formula (I), (AA) is a porous silicon nanoparticle.
