Mitochondrial reprogramming in lung cancer: a therapeutic vulnerability and a strategy for reversing drug resistance

open access: yesThe Journal of Pathology, Volume 269, Issue 2, Page 149-163, June 2026.
Abstract The conceptualization of mitochondria, previously restricted to their function as cellular ‘powerhouses’, has evolved to recognize their function as central coordinating hubs for the orchestration of cancer cell metabolism, signaling, and fate determination.

Synthesis of cyclic depsipeptides and peptides via direct amide cyclization

open access: yes, 1997
The 2,2-disubstituted 2H-azirin-3-amines 7 (2,2-disubstituted 3-amino-2H-azirines) were used as amino-acid synthons in the preparation of medium-sized cyclic depsipeptides and peptides derived from salicylic acids 6 and anthranilic acid 19, respectively (

Biosynthesis of the 15-Membered Ring Depsipeptide Neoantimycin [PDF]

open access: yesACS Chemical Biology, 2018
Antimycins are a family of natural products possessing outstanding biological activities and unique structures, which have intrigued chemists for over a half century. Of particular interest are the ring-expanded antimycins that show promising anticancer potential and whose biosynthesis remains uncharacterized. Specifically, neoantimycin and its analogs

Neuroendocrine tumours through an epigenetic lens: Emerging insights for diagnosis and treatment

open access: yesJournal of Neuroendocrinology, Volume 38, Issue 6, June 2026.
Abstract Neuroendocrine tumours (NETs) are well‐differentiated epithelial neuroendocrine neoplasms that frequently develop in the small intestine, pancreas, and lungs. NETs originate from neuroendocrine cells specialized in hormone secretion implicated in a number of physiological processes.

Activating hidden signals by mimicking cryptic sites in a synthetic extracellular matrix

open access: yesNature Communications, 2023
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.

Multi‐Targeting Non‐Specific Genome Engineering in Bacteria

open access: yesAdvanced Science, Volume 13, Issue 25, 4 May 2026.
In this study, we provide the first case to use the multi‐targeting integrase (MTI) systems in bacteria and develop a host‐independent generalizable approach, MNGE (Multi‐targeting Non‐specific Genome Engineering), for multi‐copy and random integration of metabolic genes or pathways in both Gram‐positive and Gram‐negative bacteria, which will ...

Cyclic Peptide Conformational Landscapes Through the Lens of Mass Spectrometry and Orthogonal Spectroscopy

open access: yesJournal 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 ...

Macrocyclic Peptides: Chemistry and Biology of Stapled and Depsipeptides

open access: yes, 2023
Macrocyclic peptides have been identified as key backbones in several biologically active compounds. They have been considered as great inspiration in the development of novel cyclic scaffolds in medicinal chemistry, notably in the introduction of α ...
