Scientific Reports, 2015 Cereulide and isocereulides A-G are biosynthesized as emetic toxins by Bacillus cereus via a non-ribosomal peptide synthetase (NRPS) called Ces. Although a thiotemplate mechanisms involving cyclo-trimerization of ready-made D-O-Leu-D-Ala-L-O-Val-L-Val ...

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 ...

, 2006 Generally, histone deacetylase (HDAC) inhibitor-induced p21(Waf1/Cip1) expression is thought to be p53 independent. Here we found that an inhibitor of HDAC, depsipeptide (FR901228), but not trichostatin A (TSA), induces p21(Waf1/Cip1) expression through ...

Histone Modifications in Cardiovascular Disease: Mechanisms and Therapeutic Opportunities
MedComm, Volume 7, Issue 5, May 2026.This graphical abstract summarizes how classical and emerging histone posttranslational modifications (PTMs), together with their chromatin regulators (writers, erasers, and readers), govern major pathobiological programs in cardiovascular disease.

Concise and Stereospecific Total Synthesis of Arenastatin A and Its Segment B Analogs
MoleculesA novel and concise synthetic method for arenastatin A, a cytotoxic cyclic depsipeptide of marine origin, was developed in this study. The convergent assembly of the four segments, including the cross-metathesis reaction, gave a cyclization precursor ...

Total Synthesis of the Antifungal Depsipeptide Petriellin A
, 2016 We report the solid-phase total synthesis of the antifungal highly modified cyclic depsipeptide petriellin A. The synthesis confirms earlier reports on the absolute configuration of the natural product.

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 ...
