Notizen: The identification of 6-methoxy 8-aminoquinoline as a metabolite of Primaquine, an important antimalarial drug, is described. The metabolite is present in urine, plasma and erythrocytes following drug ingestion. It was identified by mass fragmentography of its 1H and 2H acetate and the acetate produced from authentic material. No evidence of further metabolites was obtained.

Notizen: A crosslinked polybutadiene containing a cyclic depsipeptide (Valinomycin) has been synthesized in which there is some possibility of threading to produce a catenated structure (polymeric catenane). Unthreaded rings were removed by extraction with toluene. An elemental analysis indicated the yield of threaded rings to be greater than the calculated expected yield. The total amount of threaded Valinomycin present was 0.37 percent. The rings showed no effect on the calorimetric glass transition temperature, but did result in an increase in the tensile modulus.

Thema: Chemie und Pharmazie

Notizen: The mass spectra of a variety of authentic carotenoids covering a range of structural types have been studied using the field desorption technique. All the compounds examined show the molecular ion as the base peak, even where this ion is of very low intensity in the electron-impact spectra. Little fragmentation is observed, but thermal decomposition can be induced in certain cases by using higher emitter currents. Application to a simple mixture of authentic compounds and a more complex mixture of sedimentary origin shows the potential of the method in the rapid qualitative screening of carotenoids in crude extracts.

Thema: Chemie und Pharmazie

Notizen: 1H NMR spectra are reported for Michler's ketone and twenty of its derivatives, along with 13C chemical shifts for five of the compounds. 1H chemical shifts show only small changes with increasing substitution at the sterically hindered 2-position. Estimates of the dihedral angle between the benzene ring and C—CO—C planes have been obtained from the chemical shifts of C=O and 4-C for ketones 1, 3, 5, 15 and 16. These angles are both internally consistent and very similar to dihedral angles determined by other methods for corresponding compounds in the benzophenone series.

Thema: Physik

Notizen: Computer fitting techniques have been used to derive a new expression for the relationship between X-ray continuum intensity and atomic number for a range of electron acelerating potentials up to 25 kV, continuum energies up to 10 keV and average atomic numbers up to thirty. A practical approach to background corrections in energy dispersive electron microprobe analysis, which utilizes this expression, is outlined. The procedure should lead to significant improvements in both accuracy and detection limits in this method of X-ray analysis.

Notizen: Liquid membranes containing a macrocyclic polyether can move or pump a specific cation against its concentration gradient. The cation flux is not proportional to the difference of the cation concentration but to the difference of the product of cation and anion concentrations across the membrane. The results are inconsistent with existing theories of ion transport, but can be explained in terms of ion pairs.

Notizen: An expression has been derived for predicting the penetration depth of vertical jets into fluidized beds based on the experimental observations of several workers. The expression correlates a wide range of data with reasonable accuracy and is suggested as a useful working equation for design purposes.
