Abstract:

ABSTRACT An in situ reverse transcription-PCR protocol for detecting specific mRNA in Methanosarcina mazei S-6 is described. This method allowed us to detect heat shock-induced increases in the intracellular levels of the transcript of the universal stress genednaK. The cell walls of paraformaldehyde-fixed cells were permeabilized by a thermal cycling procedure or by lysozyme treatment, and the cellular DNA was removed with DNase. The cells were subjected to a seminested reverse transcription-PCR protocol in which a digoxigenin-labeled primer was used. Detection of the reporter molecule was ba

Four naphtolic glycosides (1–4), three anthraquinones (5–7), two stilbenes (8-9), one benzyl glycoside (10), and one flavonoid (11) were isolated from the roots of Fallopia multiflora. The new compounds were elucidated to be 6-hydroxymusizin 8-O-α-D-apiofuranosyl-(1→6)-β-D-glucopyranoside (1) and 6-methoxy-3-methyl-1,6,8-trihydroxy-2-naphthoic acid 8-O-β-D-glucopyranoside (3). Compound 3 could be an important marker for chemotaxonomy of F. multiflora. Benzyl gentiobioside (10) was isolated for the first time from the family Polygonaceae.

Abstract:

The hydrolysis of diphenyl (4-nitrophenyl) phosphate catalyzed by 2-iodosobenzoic and 3-iodoso-2-naphthoic acids has been studied at different pH values in the presence of hexadecyltrimethylammonium bromide as a micellar agent. It was found that 3-iodoso-2-naphthoic acid is better catalyst than 2-iodosobenzoic acid. At amounts of the acids higher than stoichiometric, the reaction is independent of pH in the 8.00 to 10.00 region while on using substoichiometric amounts, the reaction rate depends on OH- ion concentration only when the acid to diphenyl (4-nitrophenyl) phosphate molar ratio amount

The experimental data have also been interpreted by statistical methods using latent variables.

As part of ongoing research to investigate structural requirements for lactate dehydrogenase inhibition by highly substituted naphthoic acids, nine new aryl-substituted dihydroxynaphthoic acids were synthesized from three known precursors.

Naphtol blue-black was a waste that is dangerous for the environment. The research aims to determine the effect of varied concentration of the NaOH as desorption agent on the percent of desorption of naphtol blue-black from humic acid modified magnetite (Fe3O4-AH). The result of this study showed that the variation of the NaOH concentration influenced the percent of naphtol blue-black desorption from humic acid modified magnetite. The percent of desorption was 15.71 % with a concentration of NaOH was 1 M.

Abstract:

ABSTRACTThe gene encoding a nonoxidative decarboxylase capable of catalyzing the transformation of 2-hydroxy-1-naphthoic acid (2H1NA) to 2-naphthol was identified, recombinantly expressed, and purified to homogeneity. The putative gene sequence of the decarboxylase (hndA) encodes a 316-amino-acid protein (HndA) with a predicted molecular mass of 34 kDa. HndA exhibited high identity with uncharacterized amidohydrolase 2 proteins of variousBurkholderiaspecies, whereas it showed a modest 27% identity with γ-resorcylate decarboxylase, a well-characterized nonoxidative decarboxylase belonging to th

Abstract:

The solid state disorder of two tetrahydronaphthalene derivatives, N-methyl-N-methoxy-5,6,7,8-tetrahydro-1-naphthamide and 5,6,7,8-tetrahydro-1-naphthoic acid, was studied by solid state NMR and single crystal X-ray diffraction. The X-ray crystal structure of N-methyl-N-methoxy-5,6,7,8-tetrahydro-1-naphthamide was obtained at 123 K. It indicated the presence of two distinct molecular conformations. Solid state 13C CP/MAS NMR data using the dipolar dephasing technique revealed that the two conformations of the molecule are dynamically disordered, while solid state 2H NMR data, collected on a sp

Abstract:

Pharmaceutical salt-forming acid 1-hydroxy-2-naphthoic acid (HNA) is widely used in pharmaceutical co-crystal preparation. In this work, we report a new polymorph of HNA obtained during attempted co-crystallization experiments. The reported form and the new form were fully characterized and their thermodynamic relationship was also established to be monotropic with the new form being the more stable form.

Abstract:

The title compound, C40H22Cl2O4, was formed by a Michael–Aldol domino reaction sequence, which coupled acenaphthenequinone with 4-chloroacetophenone in the presence of KOH in methanol. The dihedral angles between the central cyclopenta[a]acenaphthylene fused-ring system (r.m.s. deviation = 0.066 Å) and the 4-chlorobenzoyl rings are 62.25 (10) and 70.19 (10)°. The dihedral angle between the central ring system and the naphthoic acid grouping is 62.46 (7)°. This twisting of the pendant rings facilitates the formation of an intramolecular aromatic π–π stacking interaction between the 4-chlorobenz

The structures of the Mg, Ca, Sr and Ba salts of 1-naphthoic acid are examined and compared with analogous structures of salts of benzoate derivatives.

In contrast with related benzoate salts, the naphthalene systems are large enough to prevent inorganic chain-to-chain interactions, and thus species with inorganic channels rather than lay
