4-Bromobenzene Sulfonate Derivatives: Synthesis, Characterization, DFT and Molecular Docking Study
4-bromobenzenesulfonate derivatives (I and II) were prepared and characterized by FTIR and NMR spectroscopic methods and density functional theory. Acceptable deviations were found where the scaled vibrational frequencies at B3LYP/6-311++G(d,p) were ...

Konformationsanalyse und Kinetik der Konformationsänderungen von membranaktiven Antibiotika
Molecular properties of the membrane active antibiotics enniatin B, valinomycin and gramicidin A were investigated in various solvents. The conformational rearrangements of these antibiotics have been studied as a function of solvent polarity by ...

Interaction of Aromatic Amino Acids with Metal Complexes of Tetrakis-(4-Sulfonatophenyl)Porphyrin
The interaction of a series of metal derivatives of 5, 10, 15, 20-tetrakis(4-sulfonato-phenyl)porphyrin (MTPPS4, M = Cu(II), Pt(II), Ni(II), Zn(II) and Co(II)), including the metal free porphyrin (TPPS4), with the aromatic amino acids L-tryptophan (L-Trp)
