  • Patent number: 9346741
    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.

  • Publication number: 20160075633
    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.

  • 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.

  • Patent number: 9266815
    Abstract: Disclosed herein are novel motuporamine compounds that act as anti-metastatic agents with low toxicity and high anti-migration activity. The non-toxic, anti-metastatic agents may be given to patients with potential or actual metastatic cancers, such as pancreatic cancers, alone in combination with known and/or new therapies to help block the growth and spread of tumor(s).

  • Patent number: 7972807
    Abstract: Disclosed are diagnostic tests helpful in indicating presence of an inflammatory bowel disease (IBD) in a human patient. In one embodiment, the test comprises obtaining a sample of mucosal tissue from the ileum or sigmoid colon of the patient; evaluating sample quality by testing for cadaverine and continuing the diagnostic test if the sample has no detectable cadaverine; testing the cadaverine negative sample for N-acetylated spermine; and correlating a detectable level of N-acetylated spermine in the sample with presence of IBD in the patient. Another, less invasive, method disclosed includes a diagnostic test comprising isolating mononuclear leukocytes from the patient's blood; testing the isolated mononuclear leukocytes for level of spermidine; and correlating a level of spermidine higher than that in mononuclear leukocytes of normal subjects as indicative of an inflammatory bowel disease in the patient.

  • Patent number: 7910363
    Abstract: Polyamine cationic lipids have been synthesized that have the ability to be transported into cells having an active polyamine transport system. Accordingly, these lipids may be conjugated with various agents and, thereby, act as vectors for transporting the agent into the cell aided by the cell's own polyamine transport system. A method of delivering an agent into a cell includes associating the agent with a polyamine cationic lipid selected from compounds 25, 26, 27, 28, their pharmaceutically acceptable salts and combinations thereof and contacting the cell therewith.
