3-Ketosteroid-∆1-dehydrogenase (KstD), a key enzyme in microbial steroid catabolism, catalyzes the trans-axial elimination of the C1 and C2 hydrogen atoms of the A-ring from the polycyclic ring structure of 3-ketosteroids, and it was usually used to transform androst-4-ene-3,17-dione (AD) to produce androsta-1,4-diene-3,17-dione. Here, the KstD from Gordonia neofelifaecis was expressed efficien...
The lipophilicity of a series of Schiff base ligands and their complexes with nickel(II) and copper(II) has been determined by reversed-phase thin-layer chromatography using binary dioxane-water mobile phase. Chelate ligands were prepared by condensation of diamine and the corresponding beta-diketone. Copper(II) and nickel(II) complexes with chelate ligands containing ethane-1,2-diamine or prop...

Linear and nonlinear properties of isoindoline-1,3-dione-fullerene-isoindoline-1,3-dione with the five phases were studied. The geometries combination attained using density functional theory DFT/B3LYP/6-31G+(d,p). calculated are static polarizability, anisotropy polarizability first hyperpolarizability at equilibrium geometry. In this article, theoretical design NLO molecules is discussed. res...
