Effect of C5-Methylation of Cytosine on the UV-Induced Reactivity of Duplex DNA: Conformational and Electronic Factors [PDF]

, 2016
International audienceC5-methylation of cytosines is strongly correlated with UV-induced mutations detected in skin cancers. Mutational hot-spots appearing at TCG sites are due to the formation of pyrimidine cyclobutane dimers (CPDs).

Biological Pesticides as Viable Alternative to Synthetic Pesticides for Sustainable Agriculture and Nutrition: A Systematic Review

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT The overuse of synthetic pesticides in agriculture has raised significant environmental and health concerns. Biopesticides have emerged as viable, environmentally compatible alternatives. However, recent comprehensive reviews integrating all biopesticide categories and emphasizing their contribution to synthetic‐pesticide‐free and health‐safe ...

Reversible Dihydrogen Splitting and Diradical Reactivity of 1,4‐Digermabenzene‐1,4‐diide

ChemistryEurope, Volume 4, Issue 5, May 2026.
The diradical reactivity of the 1,4‐digermabenzene‐1,4‐diide, [(ADC)Ge]2, has been demonstrated with a range of substrates. Notably, it undergoes reversible dihydrogen splitting and radical coupling with TEMPO (2,2,6,6‐tetramethylpiperidinyloxyl = RO), forming [(ADC)GeH]2 and [(ADC)Ge(OR)]2, respectively.

GC × GC‐TOF MS and Sensory Profiling of Aroma Compounds in Magnolia Species: Effects of Processing Methods on Volatile Retention in M. wufengensis

Flavour and Fragrance Journal, Volume 41, Issue 3, Page 487-503, May 2026.
The first comparative analysis of Magnolia scents reveals that M. wufengensis is characterised by a high aldehyde content, exhibiting a fresh, sweet, and fruity fragrance profile. Furthermore, freeze‐drying preserves 6.7 times more 2‐nonenal compared to shade‐drying, highlighting its superior efficacy in retaining key volatile compounds.

High Strain-Rate Response of Spiropyran Mechanophores in PMMA [PDF]

, 2014
We report the high strain-rate response of a spiropyran (SP) mechanophore in poly(methylmethacrylate). Previous work on this system has demonstrated a reversible bond scission in the SP under local tensile force, converting it to a fluorescent ...

Carbohydrate‐Based Drug Discovery: Synthetic Strategies and Clinical Applications

Israel Journal of Chemistry, Volume 66, Issue 3, May 2026.
The picture depicts the molecules discussed in the review. On the left side, the general scaffold of sugars is shown. Next to it are four carbohydrate‐based molecules, including remdesivir, islatravir, empagliflozin, and Globo‐H. Remdesivir and islatravir contain a substituted ribose ring attached to a modified nucleobase.

Unprecedented visible light-initiated topochemical [2 + 2] cycloaddition in a functionalized bimane dye

Beilstein Journal of Organic Chemistry
Bimanes, a class of molecules based on the 1H,7H-pyrazolo[1,2-a]pyrazole-1,7-dione scaffold, were first introduced by E. M. Kosower in 1978. In this study, we report the topochemical cycloaddition of diethyl 2,6-dichloro-1,7-dioxo-1H,7H-pyrazolo[1,2-a ...

RNA Modifications: Current Understandings and Future Perspectives

MedComm, Volume 7, Issue 5, May 2026.
Types of RNA modification. We have summarized the currently common types of RNA modifications, including ac4C, m6A, m1A, m5C, m3C, m7G, and ψ, and visually characterized their features through structural formulas. The characteristic structures are marked with a background color different from the background color.
