Two New Cyclic Depsipeptides from the Endophytic Fungus sp

open access: yesNatural Product Communications, 2015
Two new cyclic depsipeptides, W493 C (1) and D (2), along with two known derivatives W493 A (3) and B (4) were obtained from the endophytic fungus Fusarium sp. isolated from the Mangrove plant Ceriops tagal.

Actinomycin Derivatives: Structural Diversification and Biological Activities

open access: yesChemMedChem, Volume 21, Issue 15, 14 August 2026.
Actinomycins are chromopeptide antibiotics exhibiting remarkable structural diversity and broad bioactivity. This review traces their development from naturally occurring D‐, X‐, A‐, G‐, Y‐, and Z‐type analogs to precursor‐directed, synthetic, and semisynthetic derivatives.

Structural Diversity and Biological Activities of Cyclic Depsipeptides from Fungi

open access: yesMolecules, 2018
Cyclic depsipeptides (CDPs) are cyclopeptides in which amide groups are replaced by corresponding lactone bonds due to the presence of a hydroxylated carboxylic acid in the peptide structure.

Heat Shock Protein 90: From Molecular Chaperone Function to Therapeutic Targeting in Malignancies

open access: yesAdvanced Science, Volume 13, Issue 38, 9 July 2026.
In this review, an integrated conceptual framework linking HSP90's molecular chaperone functions to its pathological roles in cancer is proposed. HSP90 serves as a central node that integrates oncogenic signaling, buffers proteotoxic stress, maintains cancer stem cell plasticity, and shapes tumor‐immune interactions, all of which converge to drive ...

mMass as a software tool for the annotation of cyclic peptide tandem mass spectra. [PDF]

open access: yesPLoS ONE, 2012
Natural or synthetic cyclic peptides often possess pronounced bioactivity. Their mass spectrometric characterization is difficult due to the predominant occurrence of non-proteinogenic monomers and the complex fragmentation patterns observed. Even though

From Prebiotic Catalysts to Modern Applications: How Early Catalysts Inspire Today's Innovations

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 4, July 2026.
Simple catalytic systems that may have operated under prebiotic conditions offer useful molecular principles for the design of modern functional materials. By examining how amino acids, peptide assemblies, and metal complexes achieve catalysis through simple chemical features, this review highlights how prebiotic chemistry can inspire new strategies ...

Chemical Ecology of Streptomyces albidoflavus Strain A10 Associated with Carpenter Ant Camponotus vagus

open access: yesMicroorganisms, 2020
Antibiotics produced by symbiotic microorganisms were previously shown to be of crucial importance for ecological communities, including ants. Previous works on ant–actinobacteria symbiosis are mainly focused on farming ants, which use antifungal ...

Extracellular matrix and proteolysis: mechanisms driving irreversible changes and shaping cell behavior

open access: yesThe FEBS Journal, Volume 293, Issue 13, Page 3788-3813, July 2026.
Irreversible ECM proteolysis by remodeling enzymes shapes development, homeostasis, and disease. ECM‐degrading proteases display cell specificity and are governed by shared mechanisms, exhibiting functional redundancy in generating matrikines, growth factors, and cytokines.
