The crystalline compounds form ion lattices with solvent﹕eparated [(thf)4Li]+ cations and [{(thf)Li}M(C4H8)3]– anions. The NMR spectra at –20 °C show magnetic equivalence of the M–CH2 and of the β〤H2 groups of the butane4ヾiide ligands on the NMR time scale. Analogous ...

This conversion results in the full activation of the serine/threonine kinase PDK-1 (Phosphoinositide- dependent kinase), which phosphorylates and activates another serine/threonine kinase, known as AKT. PTEN (phosphatase and TENsing homolog), which functions as a kinase with tumor suppres- sor ...

Based on the results of first‐principles density functional theory calculations of the electronic structure of ThF4 in solid state and molecular form, the study of the Th6p, 5f, 6d, 7s and F2s, 2p states was done. We used the fully relativistic cluster discrete variational method with the...
