  • Patent number: 10144727
    Abstract: The present application provide novel iminosugars and their use in treatment of viral infections, such as Dengue infection and Influenza A infection. The present inventors discovered certain deoxynojirimycin derivatives may be effective against one or more viruses, which may be, for example, a Dengue virus and/or a virus belonging to the Orthomyxoviridae family, such as an Influenza A virus. In particular, such deoxynojirimycin derivatives may be useful for treating a disease or condition caused by or associated with one or more viruses. In certain embodiments, the deoxynojirimycin derivatives may increase a survival rate or probability for a subject infected with one or more viruses, which may be, for example, a Dengue virus and/or a virus belonging to the Orthomyxoviridae family, such as an Influenza A virus.

  • Patent number: 10005753
    Abstract: The present invention is directed to methods for preparing Beraprost and novel synthetic intermediates for Beraprost. In one aspect, a process is provided to produce a pharmaceutical compound represented by the general Formula (I) via a radical cyclization route. The process is completed in fewer steps than the known synthetic methods and may be conducted to prepare commercially useful quantities. In another aspect, synthetic methods are provided for producing Beraprost and its derivatives, which are stereoselective, efficient, scalable and economical. In another aspect, substantially isomerically pure compounds and intermediates are produced by the above processes.
