- Abstract
- This article focuses on reactions performed in nanostructured environments where the pair of complementary
nucleotides, 5¢-AMP and 5¢-UMP, are converted into their amphiphilic derivatives. The synthesis is carried out by
using the hydrophobic reactant dodecyl epoxide (DE) dispersed in a micellar solution based on the cationic surfactant
cetyltrimethylammoniumbromide (CTAB). Novel nucleo-lipids monomers and CTAB molecules give rise to the
spontaneous self-assembly of catanionic supramolecular structures in water, showing typical Maltese crosses in optical
microscopy. In the final colloidal suspensions, mono- and dichained derivatives have been identified in the system
incubated with 5¢-UMP through LC-QqTOF-MS analysis, whereas only mono-alkylated adducts are found in the
analogue reaction with 5¢-AMP. A new di-alkylated 5¢-UMP adduct is obtained from the 1:1 mixture of both
complementary nucleotides, in addition to the nucleo-lipids found in separate systems. Time-resolvedDLSmeasurements
reveal very different kinetic processes for aggregates' formation when 5¢-UMP, 5¢-AMP, or their equimolar combination
are used in the reaction mixture. This system as a whole represents a potential experimental model where the effect
of both intermolecular interactions and self-association processes can be investigated by tuning the type of nucleobases
in the reaction mixtures. (literal)
