Morpholines, V

Zeitschrift für Naturforschung B, 1972
A new synthesis has been developed for the hitherto unreported 2-substituted-3-oxo-4H-1,4-oxazines 3b-3j via the cyclodehydrohalogenation of N-aryl-N-dichloroacetyl-2-amino-4′-nitroacetophenones in dimethyl sulfoxide with potassium t-butoxide. The structures of all the oxazine derivatives have been verified by IR and NMR spectroscopy and correlations ...

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

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, Volume 82, Issue 4, Page 3613-3624, April 2026.
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,

Combination of a UPO‐Based Epoxidation With a Subsequent Ring‐Opening Reaction for the Synthesis of Amino Alcohols

ChemBioChem, Volume 27, Issue 5, 13 March 2026.
The synthesis of aromatic amino alcohols via a combination of an unspecific peroxygenase‐catalysed reaction, oxyfunctionalization, and addition of selected nucleophiles and electrophiles in a highly atom‐efficient manner was investigated. This study presents the design to aim for an atom‐efficient chemo‐enzymatic synthesis route towards aromatic amino ...

Exploration of morpholine-thiophene hybrid thiosemicarbazones for the treatment of ureolytic bacterial infections via targeting urease enzyme: Synthesis, biochemical screening and computational analysis

Frontiers in Chemistry
An important component of the pathogenicity of potentially pathogenic bacteria in humans is the urease enzyme. In order to avoid the detrimental impact of ureolytic bacterial infections, the inhibition of urease enzyme appears to be an appealing approach.

Unexpected Discovery of Structure‐dependent Aggregation of N‐Oxide Enables Novel Heme‐detecting Probes

Aggregate, Volume 7, Issue 3, March 2026.
N‐oxide is a polar and multifunctional group. Herein, we report a new property of this versatile group that is structure‐dependent aggregation. The first‐generation application of this new finding is to design novel heme‐detecting probes. ABSTRACT N‐oxides, characterized by a highly polar N+–O− bond, have recently demonstrated rapidly growing ...

The Contribution of Cholesterol and Squalene Synthase in Cancer: Molecular Mechanisms, Lipid Rafts and Therapeutic Approaches

Medicinal Research Reviews, Volume 46, Issue 2, Page 352-381, March 2026.
ABSTRACT A plethora of cellular signaling pathways are dysregulated in cancer cells, promoting carcinogenesis and migration. Cholesterol has recently been linked to cancer by several subcellular mechanisms, especially by its involvement in the formation of lipid rafts, which promote oncogenic signaling and cancer cell invasion. Squalene synthase (SQS),
