Pseudosaccharin amine derivatives: Synthesis and elastase inhibitory activity

Pseudosaccharin amines were synthesized from saccharin either by the reaction of pseudosaccharin chloride with amines, or via thiosaccharin which was treated with amines yielding thiosaccharinates, and their reaction with glacial acetic acid. This route gave lower yields than the first way. The synthesis of alkyl [(1,1-dioxo-benzo[d]isothiazol-3-yl)amino]alkanoates as possible Human Leukocyte Elastase (HLE) inhibitors was realized by the reaction between amino acid esters and pseudosaccharin chloride. Hydrolysis of the esters was possible under aqueous basic conditions. Selected compounds were screened for elastase inhibitory activity. Compounds 4k and 4m were found to be reversible inhibitors of HLE with Ki values of 45 muM and 60 muM.

Unusual coordination in a silver thionate complex. Synthesis, structural characterization and theoretical calculations of dinuclear and polynuclear silver(I) thiosaccharinates with pyridine and 1,10-phenanthroline

Treatment of Ag6(tsac)6 (tsac = thiosaccharinate anion) with pyridine (py) and 1,10-phenanthroline (o-phen) each affords two novel silver(I)-thiosaccharinate complexes: dinuclear [Ag2(tsac)2py] (1) and polynuclear [Ag(tsac)(o-phen)]n (2). Both crystal structures have been determined by X-ray diffraction and spectroscopic structural analysis (IR and Raman, UV-Vis, 1H and 13C NMR) have also been made for both compounds. Thermal stability analysis (TGA and DTA) of complex 1 are used to confirm the strength of the pyridine coordination to the silver ion. The molecular structure of complex 1 shows some astonishing characteristics. The two silver atoms are in different environments: one of them is surrounded by two S atoms, while the other completes its coordination sphere by three N atoms, two from the thiosaccharinate anions and the third from a pyridine molecule. The short Ag(1)-Ag(2) contact distance, 2.9681(8) A, indicates an interaction between the two silver metal atoms exists. Complex 2 shows a thiosaccharinate molecule bridging two silver atoms through the exocyclic S atom while the o-phenanthroline ligand is coordinated as a bidentate N,N chelate, forming a polynuclear chain. Quantum chemical calculations confirm the argentophilic character of the Ag-Ag interaction in complex 1, and its structure and vibrational assignments were correlated and confirmed theoretically.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: isothiazole, you can also check out more blogs about27148-03-4

Reactions of [Ru3(CO)12] with thiosaccharin: Synthesis and structure of di-, tri-, tetra- and penta-ruthenium complexes containing a thiosaccharinate ligand(s)

Reactions of [Ru3(CO)12] with thiosaccharin (tsacH) at different temperatures have been investigated. At 40 C, the diruthenium complex [Ru2(CO)6(mu-N,S-tsac)2] (1) is produced and whose ruthenium atoms are bridged by two tsac ligands that are oriented in a head-to-tail fashion. When this reaction is carried out at 66 C, the tri-, tetra- and penta-ruthenium complexes [H2Ru3(CO)7(mu-N,S-tsac)(mu-C,N?C6H4CNSO2)(mu3-S)] (2), [Ru4(CO)12(mu-N,S-tsac)2(mu4-S)] (3) and [H2Ru5(CO)13(mu-N,S-tsac)(mu-C,N?C6H4CNSO2)(mu3-S)(mu4-S)] (4), respectively, are also isolated in addition to 1. The triruthenium complex 2 exhibits an arachno SRu3 polyhedron containing edge-bridging tsac and C6H4CNSO2 ligands. The tetraruthenium complex 3 consists of two [Ru2(CO)6(mu-N,S-tsac)] fragments linked via a mu4-S ligand, while the pentaruthenium complex 4 is composed of individual Ru3 and Ru2 units linked via a mu4-S ligand. At 81 C, the same reaction furnishes the pentaruthenium complex [HRu5(CO)15(mu-N,S-tsac)(mu5-S)] (5) containing tsac and mu5-S bridging ligands. The molecular structures of the new complexes have been determined by single-crystal X-ray diffraction analyses, and the bonding in each product has been examined by DFT.

Vibrational analysis of thiosaccharin and thiosaccharinate anion. A gradient-corrected density functional and experimental study

A gradient-corrected density functional (DFT) study of thiosaccharin molecule and of the corresponding nitranion was carried out using various combinations of exchange and correlation functionals, with a special emphasis on the vibrational analysis of the studied species. The employed DFT methodologies included the B3LYP, mPW1PW91, HCTH and the OLYP combinations of functionals, using the 6-31+G(d,p) basis set for orbital expansion in solving the Kohn-Sham SCF equations. Full geometry optimizations of thiosaccharin molecule and the corresponding nitranion were carried out employing Schlegel’s gradient optimization algorithm. Subsequently, harmonic vibrational analyses were carried out for the minima located on the corresponding molecular/ionic potential energy hypersurfaces. Also, Fourier transform infrared (FT IR) spectra of thiosaccharin and a series of metal thiosaccharinates (those of Na, K, Mg, Mn, Co, Ni, Cu, Zn, Cd, Hg and Pb) were recorded at room and liquid nitrogen boiling temperature. Experimental FT IR vibrational spectra of the studied systems were analyzed in the light of the computed density functional harmonic force fields for free thiosaccharin molecule and its nitranion. The performances of various DFT methodologies employed were compared.
