A new spirocyclic proline-based lactam as efficient type II′ β-turn inducing peptidomimetic
摘要:
A new proline-based spirotricyclic lactam is reported as an efficient type II' beta-turn inducing peptidomimetic. After investigations of the reverse turn properties by Computational techniques, the scaffold has been synthesized by a straightforward sequence relying on a key RCM reaction for the construction Of the spirocyclic lactams ring. For its conformational properties, the scaffold can be considered a privileged Structure to be employed as a mimic of the beta-turn motif of the potent antibiotic Gramicidin S. (C) 2008 Elsevier Ltd.

A sequential electrochemical amide oxidation - ring closing olefin metathesis sequence has been used to overcome problems associated with the synthesis of seven-membered ring lactam containing bicyclic peptidomimetics. The synthesis of several previously unavailable bicyclic lactam building blocks for constructing constrained thyroliberin analogs is described.

Hydrophobically tagged prolyl peptides were synthesized using an electrochemically modified prolyl moiety. The hydrophobic tag served a useful handle for the repetitive reaction/separation steps during solution-phase peptide synthesis. Furthermore, the tag was also effective as an anchor on solid phases for the evaluation of activity of immobilized peptides. (C) 2009 Published by Elsevier Ltd.
