The pyridine-coordinated Cu(II) atom in the title Schiff base complex, [Cu(C(15)H(11)N(3)O(5))(C(5)H(5)N)], is O,N,O'-chelated by the doubly deprotonated Schiff base ligand. The metal centre is in a square-planar coordination geometry.
Protein-to-protein electron transfer (ET) is a critical process in biological chemistry for which fundamental understanding is expected to provide a wealth of applications in biotechnology. Investigations of protein-protein ET systems in reductive activation of artificial cofactors introduced into proteins remains particularly challenging because of the complexity of interactions between the co...
The 1H and 15N NMR spectra of several 15N-labeled pyridoxal-5'-phosphate model systems have been measured at low temperature in various aprotic and protic solvents of different polarity, i.e., dichloromethane-d2, acetonitrile-d3, tetrahydrofuran-d8, freon mixture CDF3/CDClF2, and methanol. In particular, the 15N-labeled 5'-triisopropyl-silyl ether of N-(pyridoxylidene)-tolylamine (1a), N-(pyrid...
Clinical isolates of influenza A viruses identified during outbreaks in two winters were tested for their rimantadine susceptibilities by an enzyme-linked immunosorbent assay modified from that described previously by Belshe et al. (R. B. Belshe, B. Burk, F. Newman, R. L. Cerruti, and I. S. Sim, J. Virol. 62:1508-1512, 1988). The infectivity titer and the 50% inhibitory concentration of rimanta...
The title complex, [Fe(C(12)H(9)ClNO(2))(3)], is a mononuclear Schiff base iron(III) compound. The Fe atom is six-coordinated by three phenolic O and three imine N atoms from three Schiff base ligands in an octa-hedral geometry.
Background: The heavy metals are the most important pollutants their concentration of which in the environment is increasing in connection with cities and industrials development. One of these metals is chromium which, in the trivalent and Hexavalent oxidation state, is used in industries such as electroplating, glass, ceramic, tannery and leather. Hexavalent Chromium has proven several healt...
