- Synthesis of new deuterated lipid probes for membrane fluidity measurements
-
New phosphatidylcholine analogs have been synthesized in order to be used as probes for membrane fluidity measurements in 2H-NMR experiments. A 1,3-asymmetrical diether glycerophosphatidylcholine pentadeuterated at the glycerol moiety is elaborated starting from propiolic acid in a 8-steps procedure whereas the corresponding monodeuterated compound is prepared from epibromohydrin.

- COMPOSITIONS AND METHODS FOR TREATMENT OF CENTRAL NERVOUS SYSTEM TUMORS
-
Compounds, pharmaceutical compositions, and methods for treating cancer, in particular brain cancer, are provided, including amphiphilic fatty acid/alcohol ethers (AIPs) comprising endocannabinoid and FABP motifs covalently linked to a beta-adrenoreceptor antagonist motif in one molecule. The invention includes methods for inhibiting growth of brain cancer cells by contacting the compound(s) with brain cancer cells. The invention provides a method for treating both brain cancer and brain cancer metastases, and for suppression of regrowth of brain cancer cells after radiation, surgical treatment, or chemotherapy of brain cancer. The invention also comprises an optimized chemical synthesis of the AIP compounds and methods of using the compounds, alone or in combination with another agent, for suppressing the growth of brain cancer cells, and enhancing survival of normal CNS cells, or improving recuperation from radiation, surgical or chemotherapy.

- Synthesis of natural 1- O -alkylglycerols: A study on the chemoselective opening of the epoxide ring by onium quaternary salts (N and P) and ionic liquids
-
A chemoselective route for the synthesis of 1-O-alkylglycerols chimyl (1), batyl (2), and selachyl (3) is reported. These compounds can be naturally isolated from shark liver oil and the skin of animals such as stingrays and chimeras and exhibit potential anti-fouling activity. The synthetic approach developed in this work included two distinct methods of preparation. The first was based on solvent-free reactions catalyzed by onium quaternary salts (N and P) and ionic liquids; the second methodology was based on a series of one-pot reactions.

- DIETHER BASED BIODEGRADABLE CATIONIC LIPIDS FOR siRNA DELIVERY
-
Disclosed herein are novel cationic lipids that can be used in combination with other lipid components such as cholesterol and PEG-lipids to form lipid nanoparticles with oligonucleotides. The cationic lipids can demonstrate enhanced efficacy along with lower liver toxicity as a result of lower lipid levels in the liver. The present invention employs low molecular weight cationic lipids with one short lipid chain coupled with inclusion of hydrolysable functionality in the lipid chains to enhance the efficiency and tolerability of in vivo delivery of siRNA.

- Synthesis of new fluidity-enhanced amphiphilic compounds for soluble protein two-dimensional crystallization purpose
-
The synthesis of new amphiphilic compounds is described. The structures are rationally designed for soluble protein two-dimensional (2D) crystallization purpose. Special attention is devoted to fluidity properties expected of resulting monolayers. A series of 13 compounds was prepared containing unsaturated, branched or fluorinated alkyl chains. Structures are either symmetrical or dissymmetrical and present a hydroxyl group as polar head, eventually complemented with two other 'secondary' hydrophilic functions.
