Toward developing nanostructures for single molecule detection, we report the synthesis of new derivatives of artificial devices that possess ion channel activity. The membrane stability and the ion transport ability of these multiple crown α-helical peptides have been optimized by modulating the polarity of N- and C-terminal groups with incorporation of hydrophilic non-ionic units. Circular dichroism and ATR studies confirmed the α-helical conformation and membrane incorporation of new nanostructures while 23Na NMR assays shown a significant increase of their ion transport ability.

The present invention provides organic compounds which are capable of releasing carbon monoxide under physiological conditions or pH trigger, and to the use of such compounds for conditioning a cell, tissue or organ, for example, to protect against ischaemic injury during a transplant event.
This invention relates to cationic lipids. More particularly the invention relates to biodegradable cationic lipids having a plurality of cationic headgroups and one or more lipophilic tail groups. The lipids are of utility in various applications, and in particular in permitting transfection of molecules, and in particular DNA and RNA, into cells. As such the lipids have specific utility in the field of gene therapy as well as other applications such as delivery of small molecules into cells, detergents, and metal ion complexation for medical or industrial applications.

The invention features polynucleotide constructs containing one or more components (i) containing a disulfide linkage, where each of the one or more components is attached to an internudeotide bridging group or a terminal group of the polynucleotide construct, and each of the one or more components (i) contains one or more bulky groups proximal to the disulfide group. The invention also features polynucleotide constructs containing one or more components (i) containing a disulfide linkage, where each of the one or more components (i) is attached to an internudeotide bridging group or a terminal group of the polynucleotide construct, and each of the one or more components (i) contains at least 4 atoms in a chain between the disulfide linkage and the phosphorus atom of the internudeotide bridging group or the terminal group; and where the chain does not contain a phosphate, an amide, an ester, or an alkenylene. The invention also features methods of delivering a polynucleotide to a cell using the polynucleotide constructs of the invention.
