A new series of amphiphilic cyclodextrins containing cationic groups at the 6-positions and alkyl or biolabile ester groups at the 2-positions has been synthesised. Selective 2-O-allylation followed by photochemical addition of lipophilic thiols made it possible to control lipophilicity in these mesomolecules and allow solubility and self-assembly in water. The cationic groups are cysteamine-derived, while the alkyl and ester groups are C 1-C16 and benzyl ester groups. This is a new general synthetic route to a potentially wide range of polycationic cyclodextrins capable of acting as gene delivery vectors by condensing DNA and forming liquid crystalline complexes with oligonucleotides.

Taking advantage of the high fidelity of thiol-ene and thiol-yne chemistries, we used mixtures of thiols to prepare degradable PEG-dendron amphiphiles functionalized with two different types of enzymatically cleavable end groups. By tuning the feed ratios of the two thiols, we achieved mixtures of hybrids with statistically different ratios of end groups. Studies of the disassembly of statistically mixed hybrids showed that these amphiphiles have higher degrees of response when incubated with each of the activating enzymes, whereas a greater degree of selectivity was observed for a control mixture of two distinct amphiphiles, which required the presence of both types of enzyme to undergo complete disassembly. The potential to introduce different end groups by using a mixture of thiols in an efficient single thiol-ene or thiol-yne step opens the way for simple modification of various ene- or yne-containing polymers and tailoring of their structural and functional properties.
