E. coli C43(DE3)pNbzAHabA, expressing nitroreductase and mutase enzymes, converts 2-(4-carboxyphenyl)-6-nitrobenzothiazole to 4-(6-amino-5-hydroxybenzothiazol-2-yl)benzoic acid.

Protein Tyrosine Phosphatases (PTPs) that function as negative regulators of the insulin signaling cascade have been identified as novel targets for the therapeutic enhancement of insulin action in insulin resistant disease states. Reducing Protein Tyrosine Phosphatase1B (PTP1B) abundance not only enhances insulin sensitivity and improves glucose metabolism but also protects against obesity ind...

the interaction of p-sulphonatocalix [6] arene towards l-arginine and l-lysine has been studied inacidic aqueous solution (p1-1 2) using uv-vis spectrophotometric titration technique. the psulphonatocalix[6] arene was found to be able to form 1:1 complexe with amino acids in water.the values of the association constant were determined at different temperatures to evaluate thethermodynamic funct...

Emission color changes of 4-[bis(4-methylphenyl)amino]benzylideneaniline (BMBZA) and 4-[bis(9,9-dimethylfluoren-2-yl)amino]benzylideneaniline (BFBZA) in response to hydrochloric acid (HCl) vapor solid organic acids, pentafluorobenzoic (PFBA) benzoic (BA), have been investigated their different states. BMBZA crystals changed from greenish blue reddish orange by exposure HCl vapor, whereas the em...

A total of 144 weaned crossed pigs were used in a 42-d trial to explore the effects of different concentrations/combinations of benzoic acid and thymol on growth performance and gut characteristics in weaned pigs. Pigs were randomly allotted to 4 dietary treatments: i) control (C), basal diet, ii) C+1,000 mg/kg benzoic acid+100 mg/kg thymol (BT1), iii) C+1,000 mg/kg benzoic acid+200 mg/kg thymo...

The chromogenic reagent described has been tested with seventy-nine indole derivatives and found to be very sensitive and indole-specific. The lower limit of detection on silica gel thin-layer plates was between 25 and 50 ng for most indoles. Phenols and hydroxy-, and amino-benzoic acids, hydroxy-, and methoxy-cinnamic acids did not yield chromophores with the exception of p-amino-benzoic acid ...

The title compound, C(21)H(18)N(6)O(2), was obtained as a by-product of a reaction between (E)-4-(4-dimethyl-amino-phenyl-azo)benzoic acid and 2-amino-4-(2-pyrid-yl)-6-(6-pyrid-yl)-1,3,5-triazine, which has a very low solubility, under peptidic coupling conditions, using THF as solvent. The condensation reaction occurred between 1-hy-droxy-benzotriazole and (E)-4-(4-dimethyl-amino-phenyl-azo)be...
