  • Patent number: 12060360
    Abstract: This invention relates to compounds useful as lysyl oxidase (LOX) and lysyl oxidase-like (LOXL) family member (LOXL1, LOXL2, LOXL3, LOXL4) inhibitors. In addition there are contemplated pharmaceutical compositions comprising the compounds and the use of the compounds in the treatment of conditions mediated by LOX and LOXL, for example cancer. In particular a LOX inhibitor such as the present compounds may be for use in the treatment of a cancer associated with EGFR. The present invention also contemplates the identification of biomarkers that predict responsiveness to a LOX inhibitor.

  • Patent number: 9355008
    Abstract: A performance analyzer for a self-tuning system controller, and a method for performance analysis. A range of values for a control parameter of a system controller for a system is split into a plurality of sub-ranges, need is determined to obtain a data point for a sub-range of the plurality of sub-ranges based on a criteria, wherein said sub-range is adjacent to a sub-range having a best performance value that identifies a best performance for the system, the control parameter is set to a value to generate the data point for the adjacent sub-range; and the control parameter set to a value for system performance, based on a search range determined from a window of data points that includes the generated data point.
