  • Publication number: 20210087163
    Abstract: This invention relates generally to compounds that are glucuronidase inhibitors. The glucuronidase inhibitors include phenoxy thiophene sulfonamides, and other compounds such as pyridine sulfonyls, benzene sulfonyls, thiophene sulfonyls, thiazole sulfonyls, thiophene carbonyls, and thiazole carbonyls. These compounds include nialamide, isocarboxazid, phenelzine, amoxapine, loxapine and mefloquine. Also compositions including one or more of such compounds for use in inhibiting glucuronidase and methods of using one or more of such compounds for selective inhibition of bacterial ?-glucoronidase. These compounds may be used as a co-drug in combination with the anticancer drug CPT-11. Also a method for screening compounds to determine their usefulness in reducing diarrhea associated with irinotecan chemotherapy.

  • Publication number: 20040249660
    Abstract: A system for the presentation, implementation, and administration of a defined benefit pension plan by persons other than actuaries or Enrolled Actuaries. Computer software that accepts input pertaining to the adopting entity and participants, the assets related to the Plan (if any), calculates the contribution necessary to properly fund the Plan as well as benefit levels for all participants using generally accepted actuarial methods and assumptions, automates the review and required certification of calculations by an actuary or Enrolled Actuary, and generates a printed proposal and the legal documents, forms, and other paperwork required for the implementation and on-going maintenance of the Plan. Computer software that calculates and outputs the benefit calculations of one or more participants in the Plan at any given time (referred to as a “Daily Benefit Calculation” system).
