  • Publication number: 20120128624
    Abstract: Compositions, kits and methods are provided for promoting general health or for prevention or treatment of diseases by using novel recombinant fusion proteins of human serum albumin (HSA) and bioactive molecules. The bioactive molecules may be a protein or peptide having a biological function in vitro or in vivo, and preferably, having a therapeutic activity when administered to a human. By fusing the bioactive molecule to HSA, stability of the bioactive molecule in vivo can be improved and the therapeutic index increased due to reduced toxicity and longer-lasting therapeutic effects in vivo. In addition, manufacturing processes are provided for efficient, cost-effective production of these recombinant proteins in yeast.

  • Publication number: 20090280085
    Abstract: Compositions, kits and methods are provided for Interferon analogs in order to promote general health or for therapeutic treatment of diseases. Human interferon analogs are made by fusion of interferon with human serum albumin. The bio-assay shows that the interferon analogs with the same cell protection against viral attack have 3-10 times longer acting function than interferon in vivo. These novel long acting interferon analogs can be used in treatment of patients with viral infection, such as SARS virus, HIV, HCV, HBV, or HAV, and the cancer diseases, such as leukemia and malignant melanoma. They also have a 3-5 times longer shelf-life compared with interferon.
