Cytotoxic and Antibacterial Cyclodepsipeptides from an Endophytic Fungus Fusarium avenaceum W8
MoleculesSeven cyclic depsipeptides, including two new cyclic pentadepsipeptides avenamides A (1) and B (2), were isolated from a plant-derived fungus Fusarium avenaceum W8 by using the bioassay-guided fractionation method.

Characterizing the Anti-HIV Activity of Papuamide A
Marine Drugs, 2008 Papuamide A is representative of a class of marine derived cyclic depsipeptides, reported to have cytoprotective activity against HIV-1 in vitro. We show here that papuamide A acts as an entry inhibitor, preventing human immunodeficiency virus infection ...

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

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