Considerable attention has been focused on the development of phosphonate-containing drugs for application in many therapeutic areas. However, phosphonate diacids are deprotonated at physiological pH and thus phosphonate-containing drugs are not ideal for oral administration, an extremely desirable requisite for the treatment of chronic diseases. To overcome this limitation several prodrug stru...
The effect of 3,4-dihydroxybutyl-1-phosphonate on phosphoglyceride metabolism of Escherichia coli strain 8 was examined. The compound inhibits the incorporation of [33P]phosphate into phospholipids. Phosphatidylglycerol accumulation is very strongly inhibited, while phosphatidylethanolamine and cardiolipin accumulation are less significantly affected. Pulse labeling studies using [32P]phosphate...
Activity-based probes (ABPs) are powerful tools for the analysis of active enzyme species in whole proteomes, cells or animals. Quenched fluorescent ABPs (qABPs) can be applied for real time imaging, allowing the visualization of dynamic enzyme activation by fluorescent microscopy. Unfortunately, qABPs are only available for a few enzymes. We here describe the design and synthesis of qABPs for ...
[reaction: see text] H-Phosphonate monomers of 2'-O-(2-methoxyethyl) ribonucleosides have been synthesized. Oxidation of oligonucleotide H-phosphonates has been optimized to allow the synthesis of oligonucleotides containing either 2'-deoxy or 2'-O-(2-methoxyethyl) ribonucleoside residues combined with three different phosphate modifications in the backbone, i.e., phosphodiester (PO), phosphoro...
The structures of the complexes with alpha-lytic protease of both phosphorus stereoisomers of N-[(2S)-2-[[[(1R)-1-[N-[(tert-butyloxycarbonyl)-L-alanyl-L-alanyl- L-prolyl]amino]-2-methylpropyl]-phenoxyphosphinyl]oxy]propanoyl]- L-alanine methyl ester, an analogue of the peptide Boc-Ala-Ala-Pro-Val-Ala-Ala where Val is replaced with an analogous phosphonate phenyl ester and the subsequent Ala is ...
1. P(i) competitively inhibited succinate oxidation by intact uncoupled mitochondria in the presence of sufficient N-ethylmaleimide to block the phosphate carrier, with a K(i) of 2.5mm. 2. Of a large number of phosphate esters and phosphonate compounds, phenyl phosphate and phenylphosphonate were found to inhibit competitively uncoupled succinate oxidation by intact but not broken mitochondria....
The aim of the present study was to evaluate a new multi-phosphonate surface treatment (SurfLink®) in an unloaded sheep model. Treated implants were compared to control implants in terms of bone to implant contact (BIC), bone formation, and biomechanical stability. The study used two types of implants (rough or machined surface finish) each with either the multi-phosphonate Wet or Dry treatment...
