“…However, to the best of our knowledge, no studies have been done for the selenium analogue, namely, selenoxopropanedinitrile (Se C(C N) 2 ), although the effect of sulfur and selenium for oxygen substitution has been investigated for other compounds [10][11][12]. This is also surprising because there are increasing possibilities for the synthesis of the sulfur, selenium, and even tellurium analogues of carbonyl compounds [13,14]. Very recently, Xu et al [15] reported the biosynthesis of selenocysteine on its tRNA in eukaryotes and the selenium-containing amino acid is recognized to be the 21st amino acid in the genetic code.…”

Inorganic Te(IV) compounds are important cysteine protease inhibitors and antimicrobial agents; AS-101 [ammonium trichloro (dioxoethylene-O,O′)tellurate] is the first compound of a family with formula NH 4 [C 2 H 4 Cl 3 O 2 Te], where a Te(IV) centre is bound to a chelate ethylene glycol, and showed several protective therapeutic applications. This compound is lacking in stability performance and is subjected to hydrolysis reaction with displacement of the diol ligand. In this paper, we report the stability trend of a series of analogues complexes of AS-101 with generic formula NH 4 [(RC 2 H 3 O 2)Cl 3 Te], where R is an alkyl group with different chain length and different electronic properties, in order to find a correlation between structure and stability in aqueous-physiological conditions. The stability was studied in solution via multinuclear NMR spectroscopy (1 H, 13 C, 125 Te) and computationally at the Density Functional Theory level with an explicit micro solvation model. The combined experimental and theoretical work highlights the essential role of the solvating environment and provides mechanistic insights into the complex decomposition reaction. Antimicrobial activity of the compounds was assessed against different bacterial strains. the molecular basis of the observed trend. The modelling of the reaction
