  • Patent number: 6586613
    Abstract: Substituted tetrahydro-naphthalenes and analogous compounds are prepared by reducing or condensing appropriate functional substituents in substituted tetrahydro-naphthalenes and analogous compounds by customary methods and converting functional groups in this manner into the desired groups. The compounds according to the invention are suitable for use as active compounds in pharmaceuticals, in particular in pharmaceuticals for treating arteriosclerosis and also dyslipidaemias.

  • Publication number: 20030092081
    Abstract: In a process for the quantitative optical analysis of fluorescently labelled biological cells 5, a cell layer on a transparent support at the bottom 2 of a reaction vessel 1 is in contact with a solution 3 containing the fluorescent dye 4. The sensitivity of analytical detection can be considerably improved if to the fluorescent dye 4 already present in addition a masking dye 9, which absorbs the excitation light 6 for the fluorescent dye 4 and/or its emission light 7, is added to the solution 3 and/or if a separating layer 10 permeable to the solution and absorbing and/or reflecting the excitation light 6 or the emission light 7 is applied to the cell layer at the bottom 2. This process can also be used for improving the sensitivity in the quantitative optical analysis of a luminescent biological cell layer. The separating layer 10 must in this case be composed such that it has a high power of reflection for the luminescent light 11.
