Potassium thiocyanate acts as an efficient sulfur surrogate in C-S cross-coupling reactions mediated by recyclable copper oxide nanoparticles under ligand free conditions. This protocol avoids foul smelling thiols, for the synthesis of a variety of symmetrical diaryl sulfides, via the cross-coupling of different aryl halides with potassium thiocyanate, affording corresponding products in modera...

Mice immunized with the potassium thiocyanate extract of Pasteurella haemolytica, serotype 1, were found to resist a challenge infection of P. multocida type A, thus demonstrating cross-protection. This finding was further supported by the finding that an antiserum directed against the potassium thiocyanate extract of P. haemolytica was bactericidal to P. multocida and vice versa.

To determine how a substitutionally inert metal can play a catalytic role in the metalloenzyme nitrile hydratase (NHase), a reactive five-coordinate Co(III) thiolate complex ([Co(III)(S(2)(Me2)N(3)(Pr,Pr))](PF(6)) (1)) that resembles the active site of cobalt containing nitrile hydratase (Co NHase) was prepared. This was screened for reactivity, by using low-temperature electronic absorption sp...

Abstract This work addresses the effect of chaotropic anions (thiocyanate and tosylate) on solubility glycine, L-leucine, L-phenylalanine, L-aspartic acid in aqueous solutions at 298.2 K. The salts used were NaSCN, KSCN, NH 4 SCN, NaC 7 H SO 3 (sodium tosylate), with salt concentrations ranging from 0 to 2 molal. pH saturated was registered, solid-phase studies also performed. All thiocyanate s...

In protein crystallography, spherulites are considered the result of a failed crystallization experiment. Understanding the formation of these structures may contribute to finding methods to prevent their formation. Here, we present an in situ study on lysozyme spherulites grown from sodium nitrate and sodium thiocyanate solutions, investigating their morphology and growth kinetics using optica...

We investigated the molecular basis of the activity of 4-phenoxyphenoxyethyl thiocyanate (WC-9) against Trypanosoma cruzi, the etiological agent of Chagas' disease. We found that growth inhibition of T. cruzi epimastigotes induced by this compound was associated with a reduction in the content of the parasite's endogenous sterols due to a specific blockade of their de novo synthesis at the leve...

A chemical test to distinguish smokers and nonsmokers is important in many epidemiologic studies. We have developed an automated method for determining serum thiocyanate by use of the reaction between thiocyanate and ferric ions to form a colored complex. Our data show that this method distinguishes cigarette smokers and nonsmokers: of 197 healthy individuals studied, 1.8% false-positive and 6....

We have designed and synthesized a new thiocyanate-free sensitizer coded as SPS-01 and used it as the sensitizer in a TiO(2) based nanocrystalline dye-sensitized solar cell (DSSC). SPS-01 exhibits strong visible absorption properties with maximum peak around at 532 nm. The overall power conversion efficiency (PCE) of a DSSC sensitized with SPS-01 (7.96%) is higher than that of N719 (7.30%) unde...
