| abstract |
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. |
