The versatility of a resorcinol-substituted phenanthroline-strapped porphyrin was enhanced by appending allyl chains via a double Claisen rearrangement. Two pyridine arms were then appended to the resorcinol oxygens. This multifunctional porphyrin is a suitable generic building block for the preparation of liposoluble heme protein models. X-ray(More)
Livestock farmers are known to be at high risk of exposure to zoonosis. A convenience survey to assess Senegalese traditional cattle farmers' knowledge and attitudes regarding zoonotic diseases with reference to bovine brucellosis was conducted. A total of 222 cattle farmers were interviewed. Just over a quarter (30.1%) of the study participants knew or had(More)
NHC ligands annulated to free-base porphyrins can be reversibly switched between electron-poor and electron-rich states upon protonation and deprotonation of the inner nitrogen atoms of the porphyrin. Metallation of the macrocycle with nickel(II) locks the peripheral NHC ligand in its electron-rich state.
We report herein a detailed study of the use of porphyrins fused to imidazolium salts as precursors of N-heterocyclic carbene ligands 1 M. Rhodium(I) complexes 6 M-9 M were prepared by using 1 M ligands with different metal cations in the inner core of the porphyrin (M=Ni(II) , Zn(II) , Mn(III) , Al(III) , 2H). The electronic properties of the corresponding(More)
Calf management in traditional cattle herds in many parts of the tropics receive less attention as compared to immediate income-generating cows or bulls. Information on long-term implications of poorly reared young stock is limited. A study to assess practices, challenges and opportunities during rearing of less than 12-month-old calves in traditional(More)
The molecular recognition of human telomeric G-quadruplexes by a novel cationic π-extended Ni(II)-porphyrin (Ni(II)-TImidP4) is studied in aqueous solutions via (chir)optical spectroscopy, Fluorescence Resonance Energy Transfer (FRET) melting assay, and computational molecular modeling. The results are systematically compared with the recognition by a(More)
This study compares the behavior as cytochrome c oxidase (CcO) functional and structural models of a series of reported and unreported ligands that provide either a binding site for copper without a built-in proximal base, or both a flexible binding site for copper and a built-in proximal base, or a fixed binding site for copper with a built-in proximal(More)
