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.

Method and device for detection of surface discontinuities or defects [PDF]

, 1974
Surface discontinuities of defects such as cracks and orifices are detected by applying a penetrating fluid, preferably a liquid, to a test surface so as to cause the liquid to penetrate any minute cracks or opening in the surface, removing the excess ...

Design, Synthesis, and Biological Evaluation of Novel Triazine‐Based Dual Histone Deacetylase/phosphatidylinositol 3‐kinase Inhibitors for Breast Cancer Therapy

ChemMedChem, Volume 21, Issue 8, 28 April 2026.
Breast cancer is the most frequently diagnosed malignancy and a leading cause of cancer‐related mortality among women worldwide. Triple‐negative breast cancer (TNBC) poses a major clinical challenge due to its aggressive nature, limited therapeutic options, and high propensity for drug resistance.

Fair and Square: Design, Synthesis and Biological Evaluations of Squaric Acid Derivatives as Novel HDAC8 Inhibitors

ChemMedChem, Volume 21, Issue 8, 28 April 2026.
Histone deacetylase 8 (HDAC8) is a clinically validated target in neuroblastoma, where isoform selective inhibition offers a strategy to suppress tumour growth while limiting off‐target toxicity. Hydroxamic acids remain the dominant zinc‐binding group (ZBG) in HDAC inhibitors but are also associated with metabolic instability, suboptimal ...

Regiodivergent C3 and C4 Amination of Quinolines via Radical and Ionic Pathways

Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.
A regiodivergent strategy converts a single N‐aminoquinolinium precursor into either C3‐ or C4‐aminated quinolines. Nucleophile‐induced dearomatization diverges into light‐driven N‐centered radical capture (C3) or base‐promoted SNAr (C4), enabling rapid assembly of aminoquinoline libraries and late‐stage diversification.

A Sustainable Borrowing Hydrogen Strategy in Natural Deep Eutectic Solvents for the N‐Alkylation of Amines From Alcohols

European Journal of Organic Chemistry, Volume 29, Issue 16, 25 April 2026.
A sustainable, ligand‐free Pd‐catalyzed borrowing hydrogen protocol in a biodegradable hydrophobic natural deep eutectic solvent (NADES) (thymol/DL‐menthol) enables the N‐alkylation of primary amines with benzylic alcohols under mild, aerobic conditions, allowing efficient reuse of both catalyst and solvent for seven consecutive cycles. The hydrophobic
