Substituted imidazo[1,2-a]pyridines as ?-strand peptidomimetics.


ABSTRACT: New conformationally extended dipeptide surrogates based on an imidazo[1,2-a]pyridine scaffold are described. Efficient synthesis and incorporation into host peptides affords structures with native side-chain functionality and hydrogen bonding elements on one face of the backbone. Structural analysis by NMR suggests that model peptidomimetics adopt a ?-strand-like conformation in solution.
