SUPRAMOLECULAR CHEMISTRY, MOLECULAR SELF-ASSEMBLY, FUNCTIONAL NANOSTRUCTURES, TRANSMEMBRANE ION TRANSPORT
We are making functional supramolecular structures via self-assembly.
• Supramolecular Hydrogels from natural products have promise in drug delivery and tissue engineering. We have found that potassium borate templates self-assembly of guanosine into a supramolecular hydrogel. This guanosine-borate (GB) hydrogel is stable in salt water and absorbs cationic dyes and antiviral drugs. We are working to determine the mechanism of formation and the range of applications for these hydrogels (J. Am. Chem. Soc. 2014, 136, 12596 and J. Am. Chem. Soc. 2015, 137, 5819.
Proposed Self-Assembly Mechanism for Hydrogel Formation
• Synthetic Cl – Anion Membrane Transporters. Anion transport across membranes is critical to life. Chloride channels regulate salt and fluid balance in cells. Dysfunction in chloride channels can lead to disease. Cystic fibrosis (CF) is caused by a defect in the protein that moves Cl- out of the cell. Small molecules that facilitate transmembrane transport of Cl- are attractive targets for therapeutic intervention. We have discovered a series of synthetic compounds that function in phospholipid membranes to transport Cl- anion across the bilayer. Some of the compounds appear to function by a channel mechanism, whereas others seem to operate by a carrier mechanism.
