Weak intermolecular interactions play a major role in structure formation of molecular crystals. Trimethoxy(1-naphthyl)silane (1), the first one-component single-crystalline trimethoxysilane, was analyzed by single-crystal X-ray diffraction. were studied Hirshfeld surface analysis along with 2D fingerprint plots. Both C(methyl)−H⋅⋅⋅C and C(naphthyl)−H⋅⋅⋅C found. A C(naphthyl)−H⋅⋅⋅O hydrogen bon...

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...

The Jendrassik--Groff assay for direct bilirubin was adapted for analysis rates of 150/h on the Technicon "SMAC" continuous-flow analyzer. This requires development of a standard that is compatible with the other 19 channels on this analyzer. N-1-Naphthyl ethylenediamine dihydrochloride has been used for standardization of direct bilirubin assays, but we found it to be unsuitable because values...

In vitro affinity for vascular 5HT2 and alpha receptors was determined for several compounds (spiperone, ketanserin, mianserin, trazodone, mepiprazole, benzoctamine, m-trifluoro-methylphenylpiperazine, m-chlorophenylpiperazine, and 1-(1-naphthyl)piperazine) known to interact with serotonin receptors. All compounds competitively inhibited 5HT2 and alpha receptors with differing degrees of select...

The focus of this study is to understand the origin of the chiral recognition for a host-guest system containing complexes with different stoichiometries. Each enantiomer of 2-naphthyl-1-ethanol forms two different 1 : 1 complexes with β-cyclodextrin, leading to the formation of three different 2 : 2 complexes. One of these 2 : 2 complexes leads to excimer emission of the guest. Fluorescence st...

Thermal rearrangement of propargyl naphthyl ethers produced naphthopyrans. In the presence of sodium methoxide, propargyl naphthyl ethers were converted easily to naphthofurans and naphthodifurans in good yields
