  • Publication number: 20130197088
    Abstract: The present invention is based on the seminal discovery of a synergistic effect for combinations of oligoamines with 2-difluoromethylornithine (DFMO) for treatment of cancer.

  • Patent number: 7198946
    Abstract: The invention provides methods of monitoring amyotrophic lateral sclerosis (ALS) disease development or progression and monitoring an ALS therapy by determining the level of HLA-DR expression by CD14+ monocytes and/or the percentage of CD16+ cells in the population of CD14+ cells and/or the number of CD14+/CD16+ cells in peripheral blood of an individual with ALS. The invention is also directed to methods for decreasing the number of circulating CD14+ monocytes and/or the population of CD14+/CD16+ cells and/or the number of CD14+/CD16+ cells in an individual with ALS. The invention is also directed to methods of screening for agents which decrease the population of CD14+ monocytes with elevated HLA-DR expression and/or the population of CD14+/CD16+ cells and/or the number of CD14+/CD16+ cells in an individual with ALS.

  • Publication number: 20040192665
    Abstract: Conjugates of porphyrins with chemotherapeutic agents are disclosed, as well as methods of making the conjugates and methods of treating patients with the conjugates. Porphyrin compounds, such as mesoporphyrin IX, can be covalently linked to chemotherapeutic compounds, such as doxorubicin. The resulting conjugates display decreased systemic toxicity, while preserving the antineoplastic effects of the chemotherapeutic agent. The conjugates are thus useful in treating cancer and other diseases marked by uncontrolled cell proliferation.
