Daniel L Kirschner et al.
Analytical chemistry, 79(2), 736-743 (2007-01-16)
A capillary electrophoresis method with laser-induced fluorescence detection for the chiral separation of cyanobenz[f]isoindole (CBI) derivatives of amino acids was developed and optimized. The enantioseparations are accomplished with sulfated beta-CD (S-beta-CD) as chiral selector at low pH and reverse polarity.
James Turkson et al.
Molecular cancer therapeutics, 3(3), 261-269 (2004-03-18)
The critical role of signal transducer and activator of transcription 3 (Stat3) in the growth and survival of human tumor cells identifies it as a promising target for cancer drug discovery. We previously identified a Stat3 SH2 domain-binding phosphopeptide, PY*LKTK
Federico Polo et al.
Journal of the American Chemical Society, 127(2), 492-493 (2005-01-13)
The rate constant of intramolecular electron transfer through oligopeptides based on the alpha-aminoisobutyric acid residue was determined as a function of the peptide length and found to depend weakly on the donor-acceptor separation. By measuring the electron-transfer activation energy and

The adenylation domain of nonribosomal peptide synthetase (NRPS) is responsible for the selective substrate recognition and its activation (as an acyl-O-AMP intermediate) during ATP consumption. DhbE, a stand-alone adenylation domain, acts on an aromatic acid, 2,3-dihydroxybenzoic acid (DHB). This activation
Kazuyuki Matsumura et al.
The Journal of organic chemistry, 75(16), 5461-5469 (2010-08-14)
In the Paternó-Büchi reaction of chiral p-cyanobenzoates (1) with 1,1-diphenylethene (2), we revealed that the excited charge-transfer (CT) complex formed upon selective excitation at the CT band is distinctly different in structure and reactivity from the conventional exciplex generated through
V Arjunan et al.
Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 78(5), 1449-1454 (2011-02-26)
The Fourier transform infrared (FTIR) and FT-Raman spectra of p-cyanobenzoic acid (CBA) have been recorded in the range 4000-400 and 4000-100 cm(-1), respectively. The complete vibrational assignment and analysis of the fundamental modes of the compound were carried out using
Wan-Yin Fang et al.
Chemistry, an Asian journal, 12(17), 2323-2331 (2017-07-13)
A one-pot Pd-catalyzed carbonylation of phenols into their corresponding aryl carboxylic acids and esters through the insertion of carbon monoxide has been developed. This procedure offers a direct synthesis of aryl carboxylic acids and esters from inexpensive and abundant starting
Qiao Chen et al.
Journal of protein chemistry, 22(7-8), 607-612 (2004-01-13)
Mushroom tyrosinase (EC, a copper containing oxidase, catalyzes both the hydroxylation of tyrosine into o-diphenols and the oxidation of o-diphenols into o-quinones. In the current study, the effects of 4-cyanobenzaldehyde and 4-cyanobenzoic acid on the monophenolase and diphenolase activities

Gold complexes of 4-isocyanobenzoic acid, [AuX(CNC(6)H(4)CO(2)H)] (X = C[triple bond]C-C(6)H(4)-C(9)H(19), C(6)F(5), C(6)F(4)OC(6)H(13), C(6)F(4)C(6)F(4)Br) and [(mu-4,4'-C(6)F(4)C(6)F(4)){Au(CNC(6)H(4)CO(2)H)}(2)], have been isolated. These metallo-acids are luminescent. The single crystal X-ray diffraction study of [Au(C(6)F(5))(CNC(6)H(4)CO(2)H)](infinity) confirms a rod-like structure of the molecule, with a linear
Lisa A Hoferkamp et al.
Environmental science & technology, 40(7), 2206-2212 (2006-05-02)
The reductive transformation of p-cyanonitrobenzene (pCNB) was investigated in laboratory batch slurries exhibiting dominant terminal electron accepting processes (TEAPs). Pseudo-first-order rate constants (k(obs)) were measured for the reduction of pCNB in nitrate-reducing, iron-reducing, sulfate-reducing, and methanogenic sediment slurries. Reduction was

Chemistry (Weinheim an der Bergstrasse, Germany), 21(14), 5632-5639 (2015-02-18)
A new approach has been developed to improve SO2 sorption by cyano-containing ionic liquids (ILs) through tuning the basicity of ILs and cyano-sulfur interaction. Several kinds of cyano-containing ILs with different basicity were designed, prepared, and used for SO2 capture.
Matthew Noestheden et al.
Bioorganic chemistry, 35(3), 284-293 (2007-02-24)
A recombinant VH single-domain antibody recognizing staphylococcal protein A was functionalized on reactive lysine residues with N-hydroxysuccimidyl-activated 4-cyanobenzoate. Surface plasmon resonance analysis of antibody-antigen binding revealed that modified and unmodified antibodies bound protein A with similar affinities. Raman imaging of

A new methodology of pH-metric data treatment was developed to extract the stoichiometry and the thermodynamic association constants of guest-cyclodextrin inclusion complexes in dilute aqueous solution when the guest is a participant in an acid-base equilibrium. pH-metric titration curves in
