Fluorogenic Sydnones for Bioorthogonal Labeling of DNA

open access: yesChemistry – A European Journal, EarlyView.
Conjugates of sydnones with cyanine‐styryl dyes combine bioorthogonal reactivity with fluorogenicity. The reactivity with bicyclo[6.1.0]non‐4‐yne (BCN)‐modified DNA showed second‐order rate constants of up to k2 = 2,300 M−1s−1 and fluorescence turn‐on by one magnitude of order.

Synthesis and Reactivity of a Cerium(III) Scorpionate Complex Containing a Redox Non-Innocent 2,2′-Bipyridine Ligand

open access: yesInorganics, 2015
The Ce(III) hydrotris(3,5-dimethylpyrazolyl)borate complex [Ce(TpMe2)2(κ2-dmpz)] (1) (TpMe2 = {HB(dmpz)3}−; dmpz = 3,5-dimethylpyrazolide) was isolated in fair yield from the reaction of [Ce(I)3(THF)4] with two equivalents of [K(TpMe2)] via the facile ...

A Unified Approach for the Synthesis of Conformationally Locked and sp2‐sp3 Fused Hybrids

open access: yesChemistry – A European Journal, EarlyView.
This study presents a systematic platform to build rigid sp2–sp3 hybrids via benzyne cycloadditions. Arene‑fused bicyclic oxa‐, aza‐, and carbocycles are converted into medicinally relevant amino acids and applied to Enalapril analogues synthesis. The hybrids combine aromatic interactions with 3D rigidity, tuning lipophilicity, pKa, and solubility ...

A Simple Regeneration Process Using a CO2‐Switchable‐Polarity Solvent for Cellulose Hydrogels

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The effect of transformation of the anion chemical structure on cellulose solubility by flowing CO2 gas into aqueous pyrrolidinium hydroxide solutions was investigated. The changes in anion structure allowed for the modulation of cellulose solubility in aqueous pyrrolidinium hydroxide solutions, thus establishing a simple and safe cellulose ...

Recent Advances (2023–2025) of Capillary Electrophoresis‐Mass Spectrometry (CE‐MS) for Top‐Down Proteomics

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Top‐down proteomics (TDP) characterizes proteoforms in cells, tissues, and biofluids, in discovery mode and on a global scale, requiring analytical tools with high peak capacity for proteoform separation and high sensitivity for proteoform detection, given the extremely high proteoform complexity and wide proteoform concentration dynamic range.

Transition metal complexes of 5-bromosalicylidene-4-amino-3-mercapto-1,2,4-triazine-5-one: Synthesis, characterization, catalytic and antibacterial studies [PDF]

open access: yesJournal of the Serbian Chemical Society, 2011
Transition metal complexes of 5-bromosalicylidene-4-amino-3-mercapto-1,2,4-triazine-5-one with metal precursors, such as Cu(II), Ni(II), Co(II) and Pd(II), were synthesized and characterized by physico–chemical and spectroscopic techniques.

Bio‐active designed peptide for hair keratin strengthening

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Bioactive tripeptides through in silico screening revealed KCV (Tripeptide‐132) as the most promising keratin‐targeting candidate. Experimental studies confirmed its superior hair‐strengthening performance with 44% tensile strength enhancement, 50% breakage reduction, improved surface integrity and fibre penetration.

Effects of Pretreatment of Single and Mixed Lignocellulosic Substrates on Production of Endoglucanase by Bacillus aerius S5.2

open access: yesBioResources, 2016
A mixed substrate (MS) comprising oil palm empty fruit bunch (EFB), oil palm frond (OPF), and rice husk (RH) was evaluated for endoglucanase production by Bacillus aerius S5.2. Effects of sulphuric acid, sodium hydroxide, N-methylmorpholine-N-oxide (NMMO)

DNA–Peptide Crosslinks Placed at Codon 249 of the p53 Tumor Suppressor Gene Induce G to A Transitions in Human Cells

open access: yesChemBioChem, Volume 27, Issue 16, 27 August 2026.
DNA‐peptide cross‐links (DpCs) are ubiquitous DNA lesions that form when cellular proteins become covalently trapped on DNA strands and are processed by proteases. DpCs are hypothesized to play a role in antitumor activity of chemotherapeutic drugs and to contribute to aging.
