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 ...

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.

Ratchet analysis of structures under a generalised cyclic load history [PDF]

open access: yes, 2014
This paper introduces a new approach based upon the Linear Matching Method in order to obtain the ratchet limit of structures subjected to an arbitrary thermo-mechanical load history. This method varies from the traditional Linear Matching Method ratchet

Cyclic AMP Receptor Protein from Yeast Mitochondria [PDF]

open access: yes, 1985
We have identified and characterized a cyclic AMP receptor protein in mitochondria of the yeast Saccharomyces cerevisiae. The binding is specific for cyclic nucleotides, particularly for cyclic AMP which is bound with high affinity (Kd of 10(-9) M) at 1 ...

Linear matching method on the evaluation of cyclic behaviour with creep effect [PDF]

open access: yes, 2012
This paper describes a new Linear Matching Method (LMM) technique for the direct evaluation of cyclic behaviour with creep effects of structures subjected to a general load condition in the steady cyclic state.

Anthraquinones From Epicoccum sp., a Fungus Isolated From Gut of Dione juno That Feeds on Passifloras

open access: yesChemistry &Biodiversity, Volume 23, Issue 6, June 2026.
An Epicoccum fungus was isolated from gut of larvae of the butterfly Dione juno juno that feeds intensively on leaves of Passifloras. This fungus produces hydroxyanthraquinones that moderately inhibits growth of some Bacillus that coexist with the fungus in the insect gut, suggesting that it is probably important for microbial embalance in gut flora ...

Vacuolization as a Novel Approach to Cancer Therapy

open access: yesJournal of Biochemical and Molecular Toxicology, Volume 40, Issue 6, June 2026.
This review discusses the novel strategy of inducing vacuole formation in cancer cells using small molecules, that induce nonapoptotic cell death mechanisms, such as paraptosis, oncosis, autophagy, and methuosis, and its potential in overcoming resistance to apoptosis‐based cancer therapies.

Conformational studies of free and Li+ complexed jasplakinolide, a cyclic depsipeptide from the Fijian marine sponge Jaspis splendens

open access: yes, 2005
The complexation of Li+ to jasplakinolide, a marine sponge derived cyclic depsipeptide showed preferential binding to two out of four carbonyl oxygens (C-10, C-14) and the electrons of the aromatic system of the β-tyrosine amino acid residue.

Cyclic peptides and depsipeptides from cyanobacteria: A review

open access: yesJournal of Industrial Microbiology, 1996
An elaborate array of structurally-novel and biologically-active cyclic peptides and depsipeptides are found in blue-green algae (cyanobacteria). Several of these compounds possess structures that are similar to those of natural products from marine invertebrates.
