Abstract New platinum(IV)-complexes with S-alkyl derivatives of thiosalicylic acid (alkyl = benzyl-(L1), methyl-(L2), ethyl-(L3), propyl-(L4), butyl-(L5)) have been synthesized and characterized by microanalysis, infrared spectroscopy, and 1H and 13C NMR spectroscopy. Th e bidentate S,O ligand precursor, the S-butyl derivative of thiosalicylic acid (S-bu-thiosal), was prepared, and its crystal structure was determined. Single crystals suitable for X-ray measurements were obtained by slow crystallization from a DMSO-water system. S-bu-thiosal crystallized in a P21/c space group of a monoclinic crystal system with a = 8.0732 (3) Å, b = 19.6769 (4) Å, c = 8.2291 (3) Å and Z = 4. S-bu-thiosal also has a coplanar geometry.

Abstract New zinc(II)-complexes with S-alkyl derivatives of thiosalicylic acid (alkyl = benzyl-(L1), methyl-(L2), ethyl-(L3), propyl-(L4), butyl-(L5)) have been synthesized and characterized by elemental microanalysis, IR spectroscopy, and 1H and 13C NMR spectroscopy. The S-alkyl derivatives of thiosalicylic acid were prepared by alkylation of thiosalicylic acid by adding alkyl halides to an alkaline water-ethanol solution, while the corresponding zinc(II)-complexes were obtained via the direct reaction of ZnCl2 with S-alkyl derivatives of thiosalicylic acid in water. Based on the microanalysis results and the IR and NMR spectra of the S-alkyl derivatives of thiosalicylic acid and the corresponding zinc(II)-complexes, we concluded that the ligands are bidentately coordinated to the zinc(II)-ion.

Today 3,7,10-trioxo-2,4,6,8,9,11-hexaaaza[3.3.3]propellane (THAP) has not yet received widespread re-search attention due to the complexity of the synthesis. This work is devoted to the development of a method for the THAP derivatives synthesis, as well as to the study of their biological activity in comparison with al-kyl-substituted glycolurils (subject of comparison). ТНАРwas N-alkylated to furnish novel hexaalkyl deriva-tives of ТНАРwith methyl, ethyl and propyl substituents. The conditionsfor obtaining the maximum yield of the target productwere optimizedon the base of methyl derivative. The reaction proceeded in DMSO/КОНat 75–80ºC for 13hours in a moderate yield of 56%. The ethyl and propyl derivatives of ТНАРwere synthe-sized under the same conditions. The biological activity of the obtained ТНАРalkyl derivatives and glycoluril alkyl derivatives was evaluated against Sporosarcina ureae, Bacillus pumilus, Salmonella typhimurium and Staphylococcus aureus bacteria and influenza A virus. All the samples were found to exhib-it antibacterial activity against Staphylococcus aureus.It was shown that 2,4,6,8,9,11-hexapropyl-ТНАР, di-tert-butyl-diphenyl-, di-tert-butyl-dibenzyl-, di-tert-butyl-dimethyl-and di-isopropyl-dibenzylglycoluril, have exhibited also toxicity to living cells besides antiviral activity
