Cyclic Peptide Conformational Landscapes Through the Lens of Mass Spectrometry and Orthogonal Spectroscopy

Journal of Mass Spectrometry, Volume 61, Issue 5, May 2026.
ABSTRACT Cyclic peptides occupy a structurally dynamic region of chemical space, where function often arises from ensembles rather than a single dominant fold. Closed backbones, frequent N‐methylation, heteroatoms, unnatural amino acids, and a strong propensity for metal coordination create dense conformational and coordination landscapes that ...

Regulation of cyclic lipopeptide biosynthesis in Pseudomonas fluorescens by the ClpP protease

, 2009
Cyclic lipopeptides produced by Pseudomonas species exhibit potent surfactant and broad-spectrum antibiotic properties. Their biosynthesis is governed by large multimodular nonribosomal peptide synthetases, but little is known about the genetic ...

Characterization of the Ohmyungsamycin Biosynthetic Pathway and Generation of Derivatives with Improved Antituberculosis Activity

Biomolecules, 2019
The cyclic depsipeptides ohmyungsamycin (OMS) A (1) and B (2), isolated from the marine-derived Streptomyces sp. SNJ042, contain two non-proteinogenic amino acid residues, β-hydroxy-l-phenylalanine (β-hydroxy-l-Phe) and 4-methoxy-l-tryptophan ...

Synthesis of a Carbon‐Linked Acyldepsipeptide Derivative

European Journal of Organic Chemistry, Volume 29, Issue 15, 22 April 2026.
The synthesis of a methylene‐linked acyldepsipeptide (ADEP) is reported. Success relied upon an improve method to generate a versatile vinyl glycine methyl ester synthon and a rationally optimized Grubb’s metathesis. NMR and in silico studies revealed an unusual trans–trans proline orientation for this new unnatural ADEP analog, advancing the ...

Prebiotic Organic Chemistry of Diketopiperazines

Asian Journal of Organic Chemistry, Volume 15, Issue 4, April 2026.
Diketopiperazines (DKPs) are considered essential in many life forms, but their prebiotic importance has not been fully understood. This review aims to discuss prebiotic organic chemistry for experimentally and computationally simulated reactions involving DKPs. ABSTRACT Even though the significance of amino acids and polypeptides is well recognized in

Cytotoxic Cyclic Depsipeptides from the Australian Marine Sponge Neamphius huxleyi

, 2016
Three new cyclic depsipeptides, neamphamides B (2), C (3), and D (4), were isolated from the Australian sponge Neamphius huxleyi. The planar structural characterization of these molecules was elucidated using 2D NMR experiments and ESI-FTICR-MSn.

SB-224289 Antagonizes the Antifungal Mechanism of the Marine Depsipeptide Papuamide A.

PLoS ONE, 2016
In order to expand the repertoire of antifungal compounds a novel, high-throughput phenotypic drug screen targeting fungal phosphatidylserine (PS) synthase (Cho1p) was developed based on antagonism of the toxin papuamide A (Pap-A).
