Simultaneous Multi-Harmonic Imaging of Nanoparticles in Tissues for Increased Selectivity

Sandrine Gerber, Luigi Bonacina, Solène Marcelle Françoise Marie Passemard, Davide Städler, Sébastien Courvoisier

We investigate the use of Bismuth Ferrite (BFO) nanoparticles for tumor tissue labelling in combination with infrared multi-photon excitation at 1250 nm. We report the efficient and simultaneous generation of second and third harmonic by the nanoparticles. ...

Surface Functionalisation of Alumina Ceramic Foams with Organic Ligands

Sandrine Gerber, Vincent Laporte, Pascal Miéville, Françoise Borcard, Marc Anthony Caporini

Different anchoring groups have been studied with the aim of covalently binding organic linkers to the surface of alumina ceramic foams. The results suggested that a higher degree of functionalisation was achieved with a pyrogallol derivative - as compared ...

Studies toward new anti-cancer strategies based on alpha-mannosidase inhibition

Sandrine Gerber

Changes in the glycosylation pattern of cellular glycoproteins constitute a hallmark in human cancer and influence tumour progression, suggesting that inhibitors of selected glycosidases may control cancer invasion. Following the studies on swainsonine, a ...

Pyrrolidine derivatives as new inhibitors of alpha-mannosidases and growth inhibitors of human cancer cells

Pierre Vogel, Sandrine Gerber, Hélène Fiaux

New pyrrolidine-3,4-diol derivatives were prepared from D-(-)- and L(+)-phenylglycinol and tested for their ability to inhibit 25 commercial glycosidases. The influence of the substitution of the lateral side chain and of the pyrrolidine ring on the enzyme ...

Noniterative approach to the total asymmetric synthesis of 15-carbon polyketides and analogs with high stereodiversity

Pierre Vogel, Sandrine Gerber, Marc-Etienne Schwenter, Kai Torsten Meilert

Starting from inexpensive furan and furfuryl alcohol, a noniterative approach to the synthesis of pentadeca-1,3,5,7,9,11,13,15-octols and their derivatives has been developed. The method relies upon the double [4+3]-cycloaddition of 1,1,3-trichloro-2-oxyla ...
