The invention provides an improved method of macrocyclization of peptidomimetics, as measured by isolated yields and product distribution, which comprises substitution of one or more of the backbone amide C=O bonds with a turn-inducing motif. The method is general with enhancements seen across a range of ring sizes (e.g. tri-, tetra-, penta- and hexapeptides). Specifically, the invention provides a peptidomimetic macrocycle comprising a carbonyl bioisosteric turn-inducing element having the structure: (I) wherein X is a heteroatom; and wherein R1 to R6 are each independently selected from alkyl, aryl, heteroaryl and H.

A new class of peptidomimetic is reported in which one of the amide CO bonds of the peptide backbone is replaced by an oxetane ring. They are synthesised by conjugate addition of various α-amino esters to a 3-(nitromethylene)oxetane, reduction of the nitro group and further coupling with N–Z protected amino acids to grow the peptide chain. Structural insights are provided by X-ray diffraction and molecular dynamics simulations.
