Abstract

Flexibility in rigid structures: The ability of nature to synthesize constrained disulfide-bonded cyclic molecules which adopt well-defined multiple conformational states is highlighted. Aromatic/proline interactions modulate cis–trans equilibria about Xxx–Pro bonds in the 23-membered heterocyclic ring of the contryphans isolated from cone snail venom.
