Novel 8-Hydroxyquinoline-Derived V(IV)O, Ni(II), and Fe(III) Complexes: Synthesis, Characterization, and In Vitro Cytotoxicity Against Tumor Cells

Inorganics
We report the synthesis and characterization of five novel metal complexes. Three of them are vanadium complexes with the general formula [VO(Ln)2], where Ln are Schiff bases derived from the condensation of 2-carbaldehyde-8-hydroxyquinoline with either ...

A One-Pot Biginelli Synthesis and Characterization of Novel Dihydropyrimidinone Derivatives Containing Piperazine/Morpholine Moiety

Molecules, 2018
Enaminones, 4-methyl-1-[4-(piperazin/morpholin-1-yl) phenyl] pent-2-en-1-one (IIa–b) were synthesized by refluxing 1-[4-(piperazin/morpholin-1-yl) phenyl] ethan-1-one (Ia–b) with dimethylformamide dimethylacetal (DMF–DMA) without any ...

A new method to measure EC50 reveals cultivar‐specific fungicide resistance and very high diversity within experimental field populations of Zymoseptoria tritici

Pest Management Science, EarlyView.
We isolated Zymoseptoria tritici strains from a diverse wheat field and quantified fungicide resistance using a novel plate assay. We found high diversity in fungicide sensitivity and host–fungicide–pathogen interactions. Abstract BACKGROUND Zymoseptoria tritici causes Septoria tritici blotch (STB), the most damaging wheat disease in Europe. In Europe,

Chronic morpholine exposure of rats

Fundamental and Applied Toxicology, 1989
The chronic toxicity and carcinogenic potential of morpholine were evaluated in 60 Sprague-Dawley rats/sex/group receiving morpholine at mean inhalation exposure concentrations of 0, 10, 50 and 150 ppm for 6 hr/day, 5 days/week, for 104 weeks. Survival, body weight gains, organ weights, hematology, and clinical chemistries were normal in exposed groups

From plant to fabric: Environmental opportunities associated with annatto dye for sustainable development in the textile industry

Coloration Technology, EarlyView.
Abstract Natural dyes are compounds that occur naturally in several organisms and are classified based on chemical structure and application method. The literature cites several natural dyes used in industrial transformation processes. Annatto dye is used in the food industry, and its biological pigment is extracted from the annatto seed. However, this

Bifunctional Aziridines from Photochemically Generated FSO2NH2 for SuFEx Diversification of Alkenes

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Photochemically generated FSO2NH2 serves as a safe, practical nitrene precursor for Rh‐catalyzed aziridination of alkenes, granting access to previously inaccessible fluorosulfonyl aziridines. These bifunctional electrophiles merge aziridine ring strain with SuFEx reactivity to provide a modular platform toward aliphatic sulfamoyl fluoride derivatives ...

Turn‐Induction in Peptides Incorporating Novel Cyrene‐Derived α,α‐Disubstituted Amino Acid

Journal of Peptide Science, Volume 32, Issue 3, March 2026.
Novel chiral cyrene‐derived Cyr residues were incorporated into peptides. The α,α‐disubstituted amino acid residue was introduced using the Ugi reaction. X‐ray crystallographic analysis of R‐ and S‐Cyr residues indicated preference to adopt left‐ and right‐handed α‐helical conformations, respectively.
