Polycationic compounds and uses thereof
Aspects of the present invention relate to compounds and methods useful in modulating angiogenesis and methods of treating or preventing diseases associated with angiogenesis by administering a polycationic compound. The present invention relates to methods of use and compositions for inhibiting angiogenesis-mediated disorders in mammals including animals and humans. Additionally, this invention relates to the combined use of polycations with other anti-angiogenesis agents for the treatment of different angiogenesis-mediated disorders. Additionally, those polycationic compounds can be used with various anti-inflammatory and cytotoxic agents as well as with radio-therapeutic agents in cancer patients to prevent and treat tumor growth and metastasis.
