Tamoxifen metabolites can target both aromatase and estrogen receptors
… of dual AI/SERM(D) agents. Hydroxynorendoxifen (Hdn) was identified as a novel tamoxifen metabolite, with an average plasma concentration of 0.82 nM. Nor and Hdn were potent and relatively selective AIs, with Kis of 70 nM and 20 nM, respectively. Nor and Hdn have high binding affinity for ER-α …

Preparation and Reactivity of Niobium-Containing Hydrotreating Catalysts
… for the simultaneous hydrodenitrogenation (HDN) of quinoline and hydrodesulfurization (HDS) of dibenzothiophene. The niobium oxynitride presented low HDS activity and moderate HDN activity, whereas the supported bimetallic oxycarbide was found to be highly active for both, HDN and HDS, …

Novel, High Activity Hydroprocessing Catalysts: Iron Group Phosphides
… for the simultaneous hydrodenitrogenation (HDN) of quinoline and hydrodesulfurization (HDS) of dibenzothiophene using a model liquid feed at realistic conditions (30 atm, 370 °C). The reactivity studies showed that the nickel phosphide (Ni₂P/SiO₂) was the most active of the catalysts. …

Reactivity and Structure of Supported Nickel Phosphides (Ni₂P) in Deep Hydrodesulfurization Catalysis
… were conducted in the HDS of 4,6-DMDBT and the HDN of quinoline. The performance of the catalysts will be compared to that of a conventional sulfide hydrotreating catalyst, Ni-Mo-S/Al₂O₃. Investigation of the reaction mechanism in the hydrodenitrogenation (HDN) of 2-methylpiperidine together …

Studies on the deactivation and reactivation of spent hydroprocessing catalyst
… initial coke. The hydroenitrogenation function (HDN) of the catalyst was found to be deactivated more rapidly by the initial coke than the hydrodesulphurization function (HDS). In decoking experiments, special attention was paid to the initial conditions of coke combustion, since the early stages …

Rates of evaporation of small drops at low pressures
… shown to be given by the expression (dR/dt) - (hDn(eq))/(1+hR) The rates of evaporation of small diamyl sebacate droplets were determined in a Millikan oil drop chamber, which was thermostated by a built-on water bath. To measure the radii the law relating the radius to the velocity of free fall …
