  • Publication number: 20090270506
    Abstract: The present invention relates to crystal forms of mammalian OSC and the crystal structure information obtained from them, to methods of preparing such crystal forms, and to their use for the identification and/or design of inhibitors of OSC activity. A further subject matter of the invention are methods for the identification and/or design of inhibitor compounds of OSC activity, the inhibitor compounds of OSC activity identified by these methods and their use in pharmaceutical compositions for the treatment and/or prevention of diseases which are associated with OSC comprising hypercholesterolemia, hyperlipemia, arteriosclerosis, vascular diseases, mycoses, parasite infections and gallstones, and/or treatment and/or prophylaxis of impaired glucose tolerance, diabetes, tumors and/or hyperproliferative disorders, preferably for the treatment and/or prophylaxis of hypercholesterolemia and/or hyperlipemia.

  • Patent number: 7459954
    Abstract: A control circuit for controlling an electronic circuit, which has a current path through a semiconductor switch and a line; when the semiconductor switch is switched, the inductance of the line and/or of a component in the current path producing an excess voltage between a first and a second current-carrying terminal of the semiconductor switch; the control circuit having a controllable current source for charging or discharging a charge-controlled gate of the semiconductor switch with the aid of a control current, as well as a control unit; the control unit controlling the current source in such a manner, that in the case of a switching operation, the terminal voltage across the current-carrying terminals of the semiconductor switch does not exceed a predefined setpoint terminal voltage.

  • Publication number: 20070182459
    Abstract: The invention relates to a transistor arrangement (1) comprising a transistor (10), which is provided with first and second connections (12, 14) and a control connection (16) for controlling a current flow (iD) between said first and second connections (12, 14), a signal processing device (22) exposed to the transistor control voltage (uDS) for admitting said control connection (16) according to a differential voltage (uDS) supplied between the first and second connections (12, 14) and a control device (23) which is associated with the signal processing device (22) and switches it between at least two operating modes. An inverter signal (uWR) causes, for an uWR value=0, an effect in such a way that the transistor (10) is used in the form of a conductor for uDS<0 and is locked for uDS>0. For uWR=uWR, said transistor (10) is permanently conductive.
