  • Patent number: 9926260
    Abstract: Disclosed herein are di-substituted aryl polyamine compounds and methods of making and using the same. The di-substituted polyamine compounds act as PTS targeting agents, which selectively target the polyamine transport system (PTS) with high efficacy and have improved stability in the presence of amine oxidases.

  • Patent number: 9730902
    Abstract: Novel polyamine transport inhibitors have been synthesized and demonstrated to block the uptake of native polyamines into human cancer cells. A combination therapy of the transport inhibitor and DFMO (a drug which blocks polyamine biosynthesis) provided synergistic activity against a metastatic human colon cancer cell line. The strategy uses polyamine depletion and polyamine metabolism to generate reactive oxygen species within cells as a novel way to treat cancers. This approach may be implemented for widespread use in the treatment of diseases which rely upon polyamine transport activity for proliferation.

  • Patent number: 9598351
    Abstract: Several aromatic hydrocarbons di-substituted with a polyamine are described according to formulas selected from compounds 4, 7, 10, 15 and pharmaceutically acceptable salts thereof. The novel dimeric polyamines of the present invention demonstrate enhanced penetration into cells having an upregulated polyamine transport system, such as various types of cancer cells. The disclosed aromatic polyamine dimers provide highly efficient drugs for targeting cancer cells with active polyamine transporters.

  • Publication number: 20160299149
    Abstract: Assays are described which measure polyamine transport activity and markers associated with polyamine transport and metabolism. These data are then used for the selection of treatments using therapies which target polyamine transport and polyamine metabolism. The assay includes a substrate to which a protein-containing cell sample can bind, a solution comprising a first antibody specific against ATP13A3, wherein the first antibody is configured to bind to ATP13A3 protein on the substrate, a solution comprising a second antibody specific against the first antibody, the second antibody comprising an enzyme linked thereto, wherein the second antibody is configured to bind to the first antibody.

  • Patent number: 9285320
    Abstract: Cyano-substituted anthracene containing polyamines were synthesized and shown to be efficient polyamine transporter ligands. Moreover, these compounds (3 and 4) had improved fluorescence properties over previously known anthryl-polyamine conjugates, which facilitated their intracellular trafficking by confocal microscopy and fluorescence methods. These cytotoxic fluorescent agents may find use as molecular probes which traffic into cells via the polyamine transport system and may also be viable anticancer drugs which are readily quantified in human tissues due to their excellent fluorescence properties: (excitation: ? 405 nm) and emission (420 nm) occurs in the visible light range. The ability to excite and emit in the visible range provides an advantage to these probes as these wavelengths are considered non-toxic to human cells (versus ultraviolet mediated excitations, ?<400 nm) and visible light lasers are less costly to purchase and operate than UV laser sources.
