Abstract
In the past, aminocyclohexanol rings have been successfully utilized as pH-triggered molecular switches in various trans-2-aminocyclohexanol derivatives. By changing the groups on the amine nitrogen, these models provided a wide pH range in which a switch can occur. The pH-induced switch of conformation was monitored by 1H-NMR spectroscopy. The models were also incorporated into the bilayer membrane of liposome structures and tested for their ability to disrupt their membrane upon their conformational flip induced by a decrease in pH.
In this work, the amide bond has been studied as a molecular switch and various amide derivatives have been tested for their potential as lipid-like compounds that also exhibit a pH-sensitive conformational flip. The conformational analysis of these compounds was achieved by various NMR techniques and NMR acid-base titration studies were utilized to estimate the pKa of a number of the compounds described.
