The Anticancer Activity of Organotelluranes: Potential Role in Integrin Inactivation
Silberman, Alon,Kalechman, Yona,Hirsch, Shira,Erlich, Ziv,Sredni, Benjamin,Albeck, Amnon

Organic TeIV compounds (organotelluranes) differing in their labile ligands exhibited anti-integrin activities in vitro and anti-metastatic properties in vivo. They underwent ligand substitution with l-cysteine, as a thiol model compound. Unlike inorganic TeIV compounds, the organotelluranes did not form a stable complex with cysteine, but rather immediately oxidized it. The organotelluranes inhibited integrin functions, such as adhesion, migration, and metalloproteinase secretion mediation in B16F10 murine melanoma cells. In comparison, a reduced derivative with no labile ligand inhibited adhesion of B16F10 cells to a significantly lower extent, thus pointing to the importance of the labile ligands of the TeIV atom. One of the organotelluranes inhibited circulating cancer cells in vivo, possibly by integrin inhibition. Our results extend the current knowledge on the reactivity and mechanism of organotelluranes with different labile ligands and highlight their clinical potential.
Studies on the pyrazine complexes of some diaryltellurium dihalides

Nine new Pyrazine Complexes of diaryltelluriumdihalides, R 2TeX2.Pyz (R =p-methoxyphenyl, p-hydroxyphenyl and 3-methyl- 4-hydroxy phenyl; X=Cl, Br, I; Pyz = pyrazine) have been prepared by reactions of diaryltelluriumdihalides with pyrazine in 1:1 molar ratio. These complexes have been characterized by elemental analysis, conductance and cryoscopic measurements, infrared and proton magnetic resonance spectral studies. Conductance studies in nitrobenzene, acetone and acetonitrile predict their non-electrolyte type behaviour in these solvents, which is well supported by cryoscopic data in nitrobenzene. IR and 1H NMR studies suggest the unidentate nature of pyrazine in these complexes, involving only one nitrogen atom in coordination. Thus, tellurium in R2TeX2.Pyz complexes attains a coordination number of five probably in a square pyramidal.

SYNTHESIS AND STRUCTURES OF AROMATIC AND HETEROCYCLIC TELLURIUM COMPOUNDS. XXXI. REACTIONS OF ARYLTELLURIUM OXOCHLORIDES
Rivkin, B. B.,Maksimenko, A. A.,Sadekov, I. D.
, p. 1049 - 1055 (2007/10/02)
The reactions of aryltellurium oxochlorides with the lowest aliphatic acid anhydrides lead to diaryltellurium dichlorides, Te, and CO2 through the intermediate formation of diaryltellurium chloride diacylates.Aryltellurium trichlorides and carboxylic acid anhydrides are formed in the reaction with acyl chlorides.The chlorine atom in the tellurium oxochlorides is replaced by a phenyl group on reaction with phenyllithium.The reaction with dimedone in the presence of triethylamine leads to diaryl ditellurides and a product of trimerization of a carbene, viz., a dimedone derivative that is formed in the thermal decomposition of the intermediate ylid.
