Tetrahedron

Chemical environment-dependent supramolecular assembly of 11-helical α,β2,3-hybrid peptide which give hexagonal or rod-like microcrystalline structures is demonstrated. Apart from the modulatory role by P123, sequential use of organic co-solvents during the initiation and propagation phases is shown to contribute to the size and shape regulation during molecular organization. Comparison of powder XRD data and thermal analysis results suggested that the molecular arrangement in these aggregates is similar to that in their crystals. © 2012 The Royal Society of Chemistry.

Chemical environment as control element in the evolution of shapes-'hexagons and rods' from an 11-helical α,β2,3- hybrid peptide

Variations in the lattice arrangement and the tendency toward isomorphic behavior in a group of trans-β2,3 amino acid derivatives with Boc and oxazolidinone moieties at the N- and C-terminals are discussed. The substitution pattern at the α- and β positions in these systems was found to give different torsional preferences and hence different molecular organizations in their crystals. Analysis of such preferences in their azide analogs has unraveled the involvement of a relatively uncommon carbonyl-azide dipolar interaction in lattice stabilization. © 2010 American Chemical Society.
