A series of N-Substituted 2-(benzenosulfonyl)-1-carbotioamide derivatives (WZ1-WZ4) were synthesized and characterized using spectral methods. A comprehensive activity study was performed for each compound. All compounds were tested for antibacterial activity.

- A novel type of silver nanoparticles (AgNPs) measuring 24 nm was synthesized, showing good stability and a narrow size distribution through various analysis techniques like SEM and DLS.
- The AgNPs were combined with a nontoxic hydrogel under specific conditions, and thermal analyses indicated there are no significant interactions between the AgNPs and the hydrogel fibers.
- Both the AgNPs and the AgNPs-hydrogel composites demonstrated low biological activity against a range of living cells and could be useful as drug delivery systems in therapeutic applications.
The series of -symmetric biaryl core-based non-racemic bisphosphines possessing substituents of different electronic properties: both EDG and EWG were obtained in a short sequence of good yielding transformations, started from commercial 1,3-dimethyl-2-nitrobenzene. Several different approaches leading to the desirable ligands were practically evaluated. Notably, the synthesis of the entire series of ligands could be performed with the utilization of a single early-stage precursor DIDAB (6,6'-diiodo-2,2',4,4'-tetramethylbiphenyl-3,3'-diamine), which could be easily obtained in enantiomerically pure form.
