Activating hidden signals by mimicking cryptic sites in a synthetic extracellular matrix
Cryptic sites are short signaling peptides buried within the native extracellular matrix (ECM). Enzymatic cleavage of an ECM protein reveals these hidden peptide sequences, which interact with surface receptors to control cell behavior.

Actinomycin Derivatives: Structural Diversification and Biological Activities
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.

Synthetic Strategies for Activity‐Based Probes to Decode Ubiquitin‐Like Modifiers
ABSTRACT Ubiquitin‐like proteins (Ubls) such as SUMO, NEDD8, ISG15, URM1, UFM1, FAT10, ATG8/ATG12, and FUBI are essential regulators of cellular homeostasis, controlling processes from protein stability and trafficking to immune signaling and autophagy.

Bioprospecting Indoor Bacteria Producing Bioactive Metabolites
The indoor environments served as easily accessible habitats for bacteria producing mitochondrial toxins and ionophores, effects exhibited by known antiparasitic drugs and effects useful in mitochondrial research. This study describes the bacterial species and genera producing toxic peptide antibiotics and identifies some of their biological targets in

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