The acid-base and electrochemical properties of the MLCT excited states and the one-electron-reduced forms of the three Ru(bpy)(3)(-)()(p)()(pypm)(p)()(2+) complexes, where bpy = 2,2'-bipyridine, pypm = 2-(2'-pyridyl)pyrimidine, ...

Gas-phase complexes of the formula [UO2(lig)]+ (lig = acetone (aco) or dimethylsulfoxide (dmso)) were generated by electrospray ionization (ESI) and studied by tandem ion-trap mass spectrometry to determine the general ...

Raman and infrared spectra of trimethylsulfonium dicyanamide [(CH(3))(3)SN(CN)(2)] are reported and accurately reproduced by DFT methods (B3LYP and B3PW91), MP2, and MP3, and to a lesser extent by the RHF method. The ...

Amino acid-derived phthalimide and saccharin derivatives have been investigated for their inhibitory activity toward the serine proteinases human leukocyte elastase, cathepsin G, and proteinase 3. The saccharin derivatives ...

The protective antigen is a key component of the anthrax toxin, as it allows entry of the enzymatic components edema factor and lethal factor into the host cell, through the formation of a membrane spanning pore. This event ...

There is now strong evidence for the existence of macrocyclic isomers of b(n)(+) ions, the formation and subsequent opening of which can lead to loss of sequence information from protonated peptides in multiple-stage tandem ...

A series of ascorbate derivatives has been used to examine the specificity and the chemistry of the reduction site of dopamine beta-monooxygenase (D beta M). Replacement of the 6-OH group of ascorbic acid with either bromine ...

Photoinduced electron transfer in self-assemblies of porphyrins ion-paired with ssDNA wrapped around single-wall carbon nanotubes (SWCNTs) has been reported. To accomplish the three-component hybrids, two kinds of ...

A one-step synthesis of bis-pyrrolidine functionalized fullerene-dibenzo[18]crown-6 conjugate and its metal cation complexation to the crown ether entity dependent redox behavior is reported.

Ultraviolet spectrophotometric measurements in dilute aqueous solution give pK(a) values of 8.78, 8.27, 8.96 and 8.68, respectively, for benzohydroxamic, N-phenylbenzohydroxamic, p-methoxybenzohydroxamic and N-methyl-p-m ...
