The water-insoluble and water-soluble organotin(IV)porphinate complexes based on the tris-(4-pyridinyl)porphyrin and tris(N-methyl-4-pyridiniumyl)porphyrin moieties were synthesized and characterized by elemental analysis, (1)H NMR, IR and electrospray ionization mass spectra. The in vitro activity of the compounds against P388 leukemia and A-549 was determined. The results show that the anti-t...

ESI-MS based methodology for the rapid reactivity screening of [PW(11)O(39)RhCl](5-) and [PW(11)O(39)Ir(H(2)O)](4-) toward various metalation-intended substrates (reagents with an activated C-H bond, boronic acids and organotin compounds) is presented. Formation of a series of new organometallic POM derivatives with Rh-R (R = malonate, phenylacetate, CH(3), Ph, ferrocenyl) and Ir-R (R = CH(3)) ...

Some pesticide chemicals are based on inorganic elements such as sulfur, copper (i.e. copper sulfate ‘Bordeaux mixture’, copper hydroxide, and copper oxychloride), and arsenic salts (i.e. lead arsenate, calcium arsenate, sodium arsenite), or they contain an inorganic element in their chemical structure such as the organometallic pesticides based on manganese dithiocarbamate (maneb), manganese a...

Introduction: In modern medical chemistry, much attention is paid to the search for new antimetastatic agents based on metal compounds. Organotin compounds promise be good candidates as treatment of malignant neoplasms. order reduce a possible nonspecific toxic effect tin and expand intended therapeutic use, paper presents hybrid (IV) complexes with Sn-S bond containing fragment 2,6-di-tert-but...

Five new organotin(IV) complexes of ortho-vanillin2-hydrazinopyridine hydrazone with formula [RnSnCl4–n(VHP)] [R = Me2, n = 2 (2); R = Ph2, n = 2 (3); R= nBu2, n = 2 (4); R = nBu, n = 2 (5) and R = 1, n = 0 (6)] have been synthesized by direct reaction of orthovanillin-2-hydrazinopyridine hydrazone [(VHP), (1)], base and organotin(IV) chloride(s) in absolute methanol. The hydrazone ligand [(VHP...
