Phenol is added to acetophenone (methyl phenyl ketone) and six of its halogenated derivatives in a supersonic jet expansion determine the hydrogen bonding preference cold isolated 1:1 complexes by linear infrared spectroscopy. Halogenation found have pronounced effect on docking site this intermolecular ketone balance experiment. The spectra unambiguously decide between competing variants group...
Organic solvents are often used to solubilize lipophilic new chemical entities before their addition to in vitro test systems such as microsomal stability or cytochrome P-450 (CYP) inhibition. However, the effect of these organic solvents on the test systems is not usually characterized. This study was initiated to evaluate the effect of acetonitrile and acetone, in addition to other organic so...
In 1941, Brown and Harvey described hypoglycemia after alcoholic debauch in six chronic alcoholics from the Baltimore area (1). In 1942, Tucker and Porter noted four cases among chronic alcoholics from Richmond, Virginia (2). Since then, fewer than 100 instances of alcoholism associated with hypoglycemia have been reported, and most of these accounts have appeared in the foreign literature (3-1...
A new method to achieve steady-state and dynamic-tracking desorption of organic compounds from activated carbon was developed and tested with a bench-scale system. Activated carbon fiber cloth (ACFC) was used to adsorb methyl ethyl ketone (MEK) from air streams. Direct electrothermal heating was then used to desorb the vapor to generate select vapor concentrations at 500 ppmv and 5000 ppmv in a...
