It is now commonly accepted that thiol activated creatine kinase (CK) assay systems measure CK activity more accurately and more reproducibly than non-activated systems. However, some differences have arisen in the literature in regards to the nature and course of CK activation. Some thiol compounds have been reported to yield higher enzyme activities than others. Dalal et al. (1) reported that...

In this work 3-chloro-2-chlorocarbonylbenzo[b]thiophene (1) was prepared from cinnamic acid and then converted into the acid hydrazide 2. The azomethines 3a-e were prepared from the corresponding aryl aldehydes and the acid hydrazide 2. Treatment of compound 2 with formic acid gave the N-formyl acid hydrazide 4, which upon refluxing with phosphorous pentoxide or phosphorous pentasulphide in xyl...

High Energy Materials is a term that is used for explosives, propellants and pyrotechnics. Explosives are used for military applications. 5-Picrylamino-1,2,3,4-tetrazole(PAT) is an explosive substance. In this study the reactions of the 5-Picrylamino-1,2,3,4-tetrazole(PAT) with nanostructures of fullerene and boron nitride nano-cages in different conditions of temperature, with density function...

Protein arginine deiminases (PADs) catalyze the post-translational hydrolysis of arginine residues to form citrulline. This once obscure modification is now known to play a key role in the etiology of multiple autoimmune diseases (e.g., rheumatoid arthritis, multiple sclerosis, lupus, and ulcerative colitis) and in some forms of cancer. Among the five human PADs (PAD1, -2, -3, -4, and -6), it i...

The multifunctional ‘insect kinins’ share the evolutionarily conserved C-terminal pentapeptide motif Phe-X-X-Trp-Gly-NH2, where X 1 = His, Asn, Ser, or Tyr and X = Ser, Pro, or Ala; and are associated with the regulation of diuresis in a variety of species of insects. We previously reported the functional expression of a southern cattle tick (Boophilus microplus) G protein-coupled receptor that...

In attempt to find new pharmacologically active molecules, we report here the synthesis and in vitro anti-inflammatory activity of various 1-[5-(substituted phenyl)-1-phenyl-4,5dihydro-1H-pyrazol-3-yl]-5-phenyl-1H-tetrazole (IV a-h).The anti-inflammatory activity of title compounds were examined by denaturation of proteins method. All the compounds exhibited weak to potent anti-inflammatory act...

[reaction: see text] A practical and environmentally friendly organocatalytic strategy designed to mimic the DHAP aldolases has been developed and shown to be effective in the preparation of carbohydrates and aminosugars. (S)-Proline and (S)-2-pyrrolidine-tetrazole catalyzed the aldol reaction between dihydroxy acetone variants such as 1,3-dioxan-5-one and 2,2-dimethyl-1,3-dioxan-5-one with ald...
