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.

The position of the N atom in the pentacyclic ring of heterocyclic molecules affects the excited-state decay: A case study of isothiazole and thiazole

The radiationless decay of the isothiazole and thiazole molecules in the gas phase is investigated by a combination of static MS-CASPT2 computations with dynamics simulations, and some deactivation pathways are identified leading from the lowest excited singlet (S1) state back to the electronic ground (S0) state. The dominant relaxation pathway of the excited isothiazole is found to involve out-of-plane ring deformation (ring puckering) at the C4=C5(H8)?S1 moiety, while the excited-state decay of thiazole can proceed through the ring puckering and S1?C2 bond cleavage pathways both of which happen at the S1?C2(H6) = N3 moiety. On the basis of the calculation results, we suggest that both ring-puckering and ring-opening routes should play rather important roles in the photophysics and photochemistry of heterocyclic molecules, and the position of the N atom in the heterocyclic ring has an effect on the excited state deactivation.

Release of volatile organic compounds by oxidative wear of automotive friction materials

Contribution of friction processes to the environmental pollution was proven in several studies, especially with respect to release of particulate emissions containing metals. Not too many researchers pay attention to volatile organic compounds formation during braking, although it is very relevant topic. When organic friction materials are used, the oxidative processes and thermal degradation always accompanies the friction processes during braking. A low-metallic, brake lining formulation was tested using the ISO 26867 friction evaluation standard procedure in an automotive full-scale brake dynamometer. Sampling of non-airborne debris, suspended airborne particles (PM10) and air was performed directly in the environmental chamber. Released volatiles and semi volatile organics were analyzed using GC/MS, Pyr/GC/MS, FTIR and carbon phase analysis. Occurrence of important groups of volatile organic compounds as PAHs and BTEXs with possible adverse effects on living organisms was confirmed.

Tert-Butyl 1,5-bis(4-(benzo[d]isothiazol-3-yl)piperazin-1-yl)-1,5- dioxopentan-2-ylcarbamate urea/thiourea derivatives as potent H +/K+-ATPase inhibitors

Amino acids are known to possess variable efficacy against ulceration. Considering the good antiulcer activity of amino acids, a series of urea/thiourea derivatives of glutamic acid conjugated benzisothiazole analogue 3a-u with various substituents on aryl ring were synthesized, spectroscopically characterized and evaluated for in vitro H+/K+-ATPase inhibition. Majority of the compounds possessed potency compared to that of omeprazole, a reference drug. In particular, methoxy derivatives 3p-u were the most active compounds possessing a significant 15-fold increase for para substituent thus, contributing positively to gastric H+/K +-ATPase inhibition.

Collection of ion-trap mass spectre of sulfonylurea pyrolysis products

The pyrograms of 14 sulfonylureas, i.e. herbicides characterized by high biological activity and low application dose are discussed and the mass spectra of over 30 relevant pyrolysis products as obtained with a heated filament pyrolyzer interfaced to a capillary gas chromatograph/ion-trap detector mass spectrometer are presented. Such a data compilation is useful for diagnostic purposes for both intact sulfonylureas and their metabolites after degradation in soil, because metabolites and pyrolysis products are often identical and most of their mass spectra are lacking in commercially available mass spectral libraries. The performance of the ion-trap detector based on the quality of the mass spectra is briefly discussed.

Continuation of structure?activity relationship study of novel benzamide derivatives as potential antipsychotics

A series of benzamide derivatives possessing potent dopamine D2, serotonin 5-HT1A, and 5-HT2A receptor properties were synthesized and evaluated as potential antipsychotics. Among them, 5-(4-(4-(benzo[d]isothiazol-3-yl)piperazin-1-yl)butoxy)-N-cyclopropyl-2-fluorobenzamide (4k) held the best pharmacological profile. It not only exhibited potent and balanced activities for the D2, 5-HT1A, and 5-HT2A receptors, but was also endowed with low to moderate activities for the 5-HT2C, H1, and M3 receptors, suggesting a low propensity for inducing weight gain or diabetes. In animal models, compound 4k reduced phencyclidine-induced hyperactivity with a high threshold for catalepsy or muscle relaxation induction. On the basis of its robust in vitro potency and in vivo efficacy in preclinical models of schizophrenia, 4k was selected as a candidate for further development.
