Identification of Four New agr Quorum Sensing-Interfering Cyclodepsipeptides from a Marine Photobacterium

open access: yesMarine Drugs, 2013
During our search for new natural products from the marine environment, we discovered a wide range of cyclic peptides from a marine Photobacterium, closely related to P. halotolerans.

New clinical developments in histone deacetylase inhibitors for epigenetic therapy of cancer [PDF]

open access: yes, 2009
DNA methylation and histone acetylation are two well known epigenetic chromatin modifications. Epigenetic agents leading to DNA hypomethylation and histone hyperacetylation have been approved for treatment of hematological disorders.

Effective Synthesis and Antifouling Activity of Dolastatin 16 Derivatives

open access: yesMarine Drugs, 2022
Some derivatives of dolastatin 16, a depsipeptide natural product first obtained from the sea hare Dolabella auricularia, were synthesized through second-generation synthesis of two unusual amino acids, dolaphenvaline and dolamethylleuine.

Histone deacetylases as new therapy targets for platinum-resistant epithelial ovarian cancer [PDF]

open access: yes, 2016
Introduction: In developed countries, ovarian cancer is the fourth most common cancer in women. Due to the nonspecific symptomatology associated with the disease many patients with ovarian cancer are diagnosed late, which leads to significantly poorer ...

High‐Throughput Engineering and Modification of Non‐Ribosomal Peptide Synthetases Based on Golden Gate Assembly

open access: yesAngewandte Chemie, Volume 137, Issue 49, December 1, 2025.
A Golden Gate Assembly (GGA)‐based method was developed for the efficient assembly of natural and engineered non‐ribosomal peptide synthetases (NRPS). This method has enabled the creation of NRPS libraries to generate novel peptides in high‐throughput as well as the targeted derivatisation of natural products (NPs).

Tricholides A and B and Unnarmicin D: New Hybrid PKS-NRPS Macrocycles Isolated from an Environmental Collection of Trichodesmium thiebautii

open access: yesMarine Drugs, 2017
Bioassay-guided isolation of the lipophilic extract of Trichodesmium thiebautii bloom material led to the purification and structure characterization of two new hybrid polyketide-non-ribosomal peptide (PKS-NRPS) macrocyclic compounds, tricholides A and B
