Target-directed catalytic metallodrugs
Most drugs function by binding reversibly to specific biological targets, and therapeutic effects generally require saturation of these targets. One means of decreasing required drug concentrations is incorporation of reactive metal centers that elicit irreversible modification of targets. A common approach has been the design of artificial proteases/nucleases containing metal centers capable o...
متن کاملApproaches to the design of catalytic metallodrugs.
Metal ions are known to act as catalytic centres in metallo-enzymes. On the other hand, low-molecular-weight metal complexes are widely used as catalysts in chemical systems. However, small catalysts do not have a large protein ligand to provide substrate selectivity and minimize catalyst poisoning. Despite the challenges that the lack of a protein ligand might pose, some success in the use of ...
متن کاملCatalytic antioxidant therapy by metallodrugs: lessons from metallocorroles.
SIGNIFICANCE the fundamental science behind the "antioxidant therapy", i.e., the importance of eliminating oxidizing species that may damage vital biomolecules and induce biological malfunctions, is well established. Nevertheless, quite disappointing results were reported in several recent meta-analyses that addressed the effects of vitamins and other antioxidant supplements on the many disease...
متن کاملCatalytic metallodrugs based on the LaR2C peptide target HCV SLIV IRES RNA.
Prior work has demonstrated the potential effectiveness of a new class of metallopeptides as catalytic metallodrugs that target HCV IRES SLIIb RNA (Cu-GGHYrFK, 1). Herein new catalytic metallodrugs (GGHKYKETDLLILFKDDYFAKKNEERK, 2; and GGHKYKETDL, 3) are described based on the LaR2C peptide that has been shown to bind to the SLIV HCV IRES domain. In vitro fluorescence assays yielded KD values ∼1...
متن کاملIron Metallodrugs: Stability, Redox Activity and Toxicity against Artemia salina
Iron metallodrugs comprise mineral supplements, anti-hypertensive agents and, more recently, magnetic nanomaterials, with both therapeutic and diagnostic roles. As biologically-active metal compounds, concern has been raised regarding the impact of these compounds when emitted to the environment and associated ecotoxicological effects for the fauna. In this work we assessed the relative stabili...
