Organotin-drug interactions. Organotin adducts of tenoxicam: Synthesis and characterization of the first organotin complex of tenoxicam

, 2000
The synthesis and spectral characterization of the novel organotin complexes [SnBu2(ten)] (1) and [SnBu2(Hten)(2)] (2) or the potent and widely used anti-inflammatory drug tenoxicam (H(2)ten) are reported. A crystal-structure determination of 1 showed that, in this complex, the ligand is doubly deprotonated at the hydroxy O-atom and the amide N atom ...

Phosphoryl Halogen and Hydrogen Bonding Controls the Solid‐State Structures of Aryl Halide‐Containing Phosphonates

European Journal of Inorganic Chemistry, Volume 29, Issue 17, 17 June 2026.
Intramolecular (RO)2PO→Halogen interaction versus intermolecular (RO)2PO···HOH hydrogen bonds. Although the O···I distance is shorter than the sum of the van der Waals radii of the atoms involved, there is no covalency involved in this interaction.

Durable Biofouling‐Resistant Coated Fabric Based on Aerogel/Polyurethane for Marine Applications

Macromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.
A multilayer composite protective fabric (PUC‐CME/KF) is developed by integrating carboxymethyl chitosan/coral extract aerogel and capsaicin‐loaded polyurethane onto a knitted substrate. The material exhibits exceptional extensibility (1963% elongation at break) and sustained capsaicin release.

Surficial N+ Charge Density as Key Factor for Inhibition of Pseudomonas Biofilm Formation in Non‐Leaching Quaternary Ammonium‐Modified Polydimethylsiloxane Coatings

Chemistry – A European Journal, Volume 32, Issue 14, 15 April 2026.
Biological fouling threatens marine ecosystems and infrastructures, demanding sustainable solutions. We designed PDMS materials functionalized with quaternary ammonium‐based silanes that inhibit biofilm formation of a highly resilient Gram‐negative Pseudomonas strain.

Synthesis of Sulfur Heterocycles by Palladium‐Catalyzed Cyclization

European Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.
In spite of the well‐known palladium thiophilicity, sulfur‐containing acyclic substrates may efficiently undergo several different kinds of palladium‐catalyzed cyclization processes leading to highly important sulfur heterocycles in one synthetic step. Advances in this challenging and stimulating field of research are presented in this review.
