Origin and characterization of cyclodepsipeptides: Comprehensive structural approaches with focus on mass spectrometry analysis of alkali‐cationized molecular species

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract Cyclodepsipeptides (CDPs) represent a huge family of chemically and structurally diverse molecules with a wide ability for molecular interactions. CDPs are cyclic peptide‐related natural products made up of both proteinogenic and nonproteinogenic amino acids linked by amide and ester bonds.

Direct Ambient Mass Spectrometry for Food, Beverage, and Agricultural Sample Analysis and Research

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Ambient and direct mass spectrometry (MS) methods are becoming increasingly used for the rapid analysis of food, beverage and agricultural samples. Novel ionization approaches combined with targeted, or untargeted workflows provide analytical outcomes within a greatly reduced time period compared to traditional separation science coupled with ...

Simultaneous T1, T2, and T1ρ mapping of the myocardium using cardiac MR fingerprinting with a deep image prior reconstruction

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose To develop a cardiac MR fingerprinting (cMRF) approach using deep image prior reconstruction (DIP) to simultaneously map T1, T2, and T1ρ, and assess T1ρ in healthy subjects and patients with areas of enhancement on late gadolinium enhancement.

Efficient Synthesis of 1‐Chloroimidazo[1,2‐a:4,5‐c']dipyridines, Versatile Synthons for Position‐1 Functionalisation with Various Reagents

open access: yesChemistryOpen, EarlyView.
Imidazo[1,2‐a:4,5‐c']dipyridines are remarkable skeletons in the field of medicinal chemistry. This article presents the synthesis of 1‐chloroimidazo[1,2‐a:4,5‐c']dipyridines, versatile synthons to functionalize at position‐1. Several examples of further reactions are presented, including Suzuki–Miyaura and Sonogashira cross‐couplings, nucleophilic ...

Controlling Drug Release From Supramolecular Polymer Surfaces by a Click‐To‐Release Reaction

open access: yesJournal of Polymer Science, EarlyView.
We present a strategy combining reactive supramolecular additives with a covalent click‐to‐release reaction for localized drug delivery. A trans‐cyclooctene additive releases a cytotoxic drug upon tetrazine administration. Fluorescent monitoring confirms release, and cytotoxic tests show effective cancer cell death.

Late Bowel Symptoms in Long‐Term Survivors of Prostate Cancer Following Radiotherapy

open access: yesThe Prostate, EarlyView.
ABSTRACT Background Despite advances in radiotherapy planning, some long‐term prostate cancer survivors experience persistent symptoms. Although overall quality of life appears comparable between patients treated with definitive and salvage radiotherapy and aligns with normative data, prostate‐specific deficits—particularly bowel symptoms—may persist ...
