The interaction of spermine and its analogue, 1-naphthyl acetyl spermine with four double stranded DNA polynucleotides has been studied to understand the structural and thermodynamic basis of the binding. The efficacy and specificity of DNA binding of this analogue has not yet been revealed. The energetics of the interaction was studied by isothermal titration calorimetry and differential scann...

substituted naphthofurans and naphthopyrans were constructed at high temperature from allyl or propargyl naphthyl ethers via claisen rearrangement in moderate to good yields. also, substituted (trimethylsilyl)-naphthofurans were synthesized from the corresponding naphtofurans.

We have developed a new photoremovable protecting group for caging phosphates in the near UV. Diethyl 2-(4-hydroxy-1-naphthyl)-2-oxoethyl phosphate (14a) quantitatively releases diethyl phosphate upon irradiation in aq MeOH or aq MeCN at 350 nm, with quantum efficiencies ranging from 0.021 to 0.067 depending on the solvent composition. The deprotection reactions originate from the triplet excit...

We aimed to research the influences of oral L.plantarum administration on some blood parameters and alpha-naphthyl acetate esterase (ANAE)-positive lymphocyte ratios in female rats exposed chronically Cd. In order perform this investigation, were separated into four equal groups as control (C, n = 8), cadmium (Cd, (n Cd+ 8). Cd (2.04 mg / mL) was orally applicated for 28 days. addition, active-...

A one-pot synthesis of (S)-(-)-propranolol is reported. Zn(NO3)2/(+)-tartaric acid catalyzed enantioselective synthesis of (S)-(-)-propranolol via kinetic resolution of key intermediate ?-naphthyl glycidyl ether with high optical and chemical yield.

The title mol-ecule, C26H16O2, crystallizes as a mol-ecular crystal with no strong inter-molecular inter-actions (the shortest C-H⋯O contact is longer than 3.4 Å). Two flat ace-naphthyl-ene groups of neigboring 1,2-di-benzoyl-ace-naphthyl-ene mol-ecules are related by a crystallographic center of symmetry and are stacked with the distance between their mean planes of 3.37 (1) Å, apparently maki...

Peripheral blood T lymphocytes have been reported to express the alpha-naphthyl acetate esterase (ANAE) enzyme after maturation of thymocytes in the medulla of the thymus [5]. ANAE is a lysosomal enzyme [20, 21, 29]. ZICCA et al., [29] reported that the enzyme is found in the membranes of the lysosomes, while ASTI et al., [3] reported the lysosomal content of the enzyme. Because the enzyme was ...
