要旨

Murepavadin (POL7080) in phase III clinical trials, a backbone-cyclized polypeptide composed of 14 amino acids, has a novel mode of action and shows a specific and efficient bactericidal effect against multidrug-resistant Pseudomonas aeruginosa. It is a potential candidate to treat severe P. aeruginosa infections in the future and still has significant commercial value for further research and development. In this paper, we report a liquid-phase peptide synthetic route for this valuable candidate polypeptide assisted by hydrophobic-support materials (tags), which overcomes the difficulties of high cost and poor yield in the traditional solid-phase synthesis of macrocyclic peptides. Through the careful optimization of reaction conditions and the innovative strategy of synthetic post-treatment, we established a simple and efficient liquid-phase synthetic route suitable for POL7080 and other similar structures, with satisfactory yield, high purity and a production process not being controlled by scale.

Organic & Biomolecular Chemistry (OBC) publishes original and high impact research and reviews in organic chemistry. We welcome research that shows new or significantly improved protocols or methodologies in total synthesis, synthetic methodology or physical and theoretical organic chemistry as well as research that shows a significant advance in the organic chemistry or molecular design aspects of chemical biology, catalysis, supramolecular and macromolecular chemistry, theoretical chemistry, mechanism-oriented physical organic chemistry, medicinal chemistry or natural products. Articles published in the journal should report new work which makes a highly-significant impact in the field. Routine and incremental work is generally not suitable for publication in the journal. More details about key areas of our scope are below. In all cases authors should include in their article clear rationale for why their research has been carried out.
