Metal-based complexes with their unique chemical properties, including multiple oxidation states, radio-nuclear capabilities and various coordination geometries yield value as potential pharmaceuticals. Understanding the interactions between metals biological systems will prove key for site-specific of new metal-based lead compounds. This study merges concepts target fragment-based drug methodologies, supported by varying anomalous scattering rhenium along infrared spectroscopy, has...
Abstract Direct mixing (de novo) and Solvent Assisted Ligand Exchange (SALE) are the main methods used for synthesis of Mixed-Linker Zeolitic Imidazolate Frameworks (ML-ZIFs). ML-ZIFs with combined –NO 2 –Br/–Cl functionalities were prepared via both synthetic routes. Thereafter CO uptake compared, as well their abilities to fixate epoxide substrates. The de novo resulted in SOD topologies, 60: 40 (–NO : –Br/–Cl) functionality ratios, higher porosities, better thermal stability than...
The retention of the covalent binding an organometalllic rhenium complex to a protein at physiological body temperature (37 °C) is described and compared related 100 K crystal structure.
A series of seven fac-[Re(CO)3(5Me-Sal-Trypt)(L)] complexes containing tryptamine on the N,O 5-methyl-salicylidene bidentate ligand backbone and where L is MeOH, Py, Imi, DMAP, PPh3 coordinated to 6th position have been studied, including formation a dinuclear Re2 cluster. The crystallographic solid state structures show marked similarity in structural tendency, particular rigidity Re core hydrogen bond interactions similar those found protein structures. rates stability were evaluated by...

Nucleation of collagen-fold formation has been followed by D-H exchange techniques coupled with infra-red measurements the Arnide II absorbance at 1550 cm-'. Solution Sephadex and thin film were applied to two gelatin fractions differing in molecular weight chain cross-linking. The rate was measured temperatures, T above below melting temperature, TM. At T> TM classes exchangeable H detected. On basis their pD-rate profiles, these assigned pyrollidine ring rich sequences t o deficient...
