title: C-linked galactosyl serine AFGP analogues as potent recrystallization inhibitors.
abstract: [reaction: see text] A series of C-linked antifreeze glycoprotein analogues have been prepared to evaluate antifreeze activity as a function of distance between the carbohydrate moiety and polypeptide backbone. The building blocks for these analogues were prepared using either an olefin cross-metathesis or catalytic asymmetric hydrogenation. Analysis of antifreeze protein-specific activity revealed that only analogue 2a (n = 1) was a potent recrystallization inhibitor and thus has potential medical and industrial applications.
