Biomimetic peptoid oligomers as dual-action antifreeze agents. Huang, M., L., Ehre, D., Jiang, Q., Hu, C., Kirshenbaum, K., & Ward, M., D. PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA, 109(49):19922-19927, NATL ACAD SCIENCES, 12, 2012. abstract bibtex The ability of natural peptides and proteins to influence the formation
of inorganic crystalline materials has prompted the design of synthetic
compounds for the regulation of crystal growth, including the freezing
of water and growth of ice crystals. Despite their versatility and ease
of structural modification, peptidomimetic oligomers have not yet been
explored extensively as crystallization modulators. This report
describes a library of synthetic N-substituted glycine peptoid oligomers
that possess ``dual-action'' antifreeze activity as exemplified by ice
crystal growth inhibition concomitant with melting temperature
reduction. We investigated the structural features responsible for these
phenomena and observed that peptoid antifreeze activities depend both on
oligomer backbone structure and side chain chemical composition. These
studies reveal the capability of peptoids to act as ice crystallization
regulators, enabling the discovery of a unique and diverse family of
synthetic oligomers with potential as antifreeze agents in food
production and biomedicine.
