1. Certain of the alpha-mercapto soaps and alpha-disulfo soaps are powerful germicides. 2. In the alpha-mercapto series, those soaps with 12 and 14 carbon atoms are most germicidal. In the disulfo series, the dicaprate, dilaurate, and dimyristate are most germicidal. The optimum number of carbon atoms varies with the test organism used. 3. These soaps, like others previously studied, show a mar...

The title salt, [Ni(C3H2NS2)(C12H8N2)2]PF6·1.5C4H8O2, was the unexpected product on making an attempt to prepare an [Ni(2-mercapto-thia-zol-ate)(1,10-phenanthroline)]+ complex by reaction of [NiCl2(1,10-phen-an-throline)] with 2-mercapto-thia-zolate. In the resulting complex, the 2-mercapto-thia-zolate anion acts as a chelating ligand, which coordinates to the NiII ion with the thia-zolyl N and...

Some new 2-alkyl-5-mercapto-1,3,4-Oxadiazoles and 3-alkyl-5-mercapto-1,2,3-4H triazoles were synthesized from hydrazides of acid oil and oil recovered from spent bleaching earth. These newly synthesized compounds were characterized on the basis of elemental analysis and evaluated for biological properties. Certain derivatives exhibited fairly high antibacterial and antifungal activities when co...

Acylisothiocyanate (1) was allowed to react with benzylidene malononitrile producing oxazine derivative (2). Also, compound (1) was reacted with sodium azide followed by refluxing with sodium ethoxide affording thiazinotetrazole derivative (4). The reaction of acetylacetone with compound (1) gave pyridine derivative (5) by intramolecular cycloaddition while it was reacted with N-methyl aniline ...

Surface reactive nanostructures were fabricated using stimulated emission depletion (STED) lithography. The functionalization of the nanostructures was realized by copolymerization of a bifunctional metal oxo cluster in the presence of a triacrylate monomer. Ligands of the cluster surface cross-link to the monomer during the lithographic process, whereas unreacted mercapto functionalized ligand...

Polyfunctional thiols are known to have a strong impact on the overall aroma of many fermented foods. Surprisingly, very little data is available on their occurrence in beer. A specific extraction with p-hydroxymercuribenzoic acid was performed on four different fresh light-protected lager beers. gas chromatography-olfactometry, gas chromatography-mass spectrometry, and gas chromatography-pulse...

In order to determine how functionalized gold nanoparticles (AuNPs) interact in a near-physiological environment, we performed all-atom molecular dynamics simulations on the icosahedral Au144 nanoparticles each coated with a homogeneous set of 60 thiolates selected from one of these five (5) types: 11-mercapto-1-undecanesulfonate -SC11H22(SO3(-)), 5-mercapto-1-pentanesulfonate -SC5H10(SO3(-)), ...

Current assays of phospholipase A1 (EC 3.1.1.32) and monoacylglycerol lipase (EC 3.1.1.23) activities in tissues are discontinuous, laborious, and expensive. Some spectrophotometric substrates were synthesized to alleviate this problem. Thioester analogs of phosphatidylcholine and phosphatidylethanolamine. rac-1,2-S,O-didecanoyl-3-phosphocholine-1-mercapto-2,3-propanediol and rac-1,2-S,O-dideca...

In this research, mercapto-silica coated magnetite (Fe3O4-SiO2-SH) has been prepared in aqueous solution through a simple approach so called a one-pot process. The Fe3O4-SiO2-SH was prepared in nitrogen condition by mixing magnetite, 3-mercaptopropyltrimethoxysilane (MPTMS), and sodium silicate (Na2SiO3) solution extracted from rice hull ash, and adjusting the pH of 7.0 using hydrochloric acid....
