Chlorodefluorination reactions of fluoromethanes and fluoroolefins catalysed by the highly Lewis acidic nanoscopic aluminum chlorofluoride (ACF, AlClxF3−x, x≈0.05–0.3) in presence ClSiEt3 were studied. Both convert under mild reaction conditions fluorine-chlorine exchange steps into chlorinated fluoro derivatives. MAS NMR studies provided information on interaction silanes hexafluoropropene wit...
Aluminum (Al) can cause neurotoxicity, a low-turnover osteomalacia, and microcytic anemia. To test the null hypothesis that the chemical form (species) of Al does not influence its mechanism or rate of absorption from the gastrointestinal tract, Al flux across and uptake into Caco-2 cells was investigated. Caco-2 cells were grown on porous membranes mounted in vertical diffusion chambers or in ...
Activation of a heterotrimeric G-protein by an agonist-stimulated G-protein coupled receptor requires the propagation of structural signals from the receptor binding interface to the guanine nucleotide binding pocket of the G-protein. To probe the molecular basis of this signaling process, we are applying high-resolution NMR to track structural changes in an isotope-labeled, full length G-prote...
