Cancer Therapy Using Vasoactive Intestinal Peptide Antagonists
Posted Jun 15 2010 5:00pm
Description of Invention: The second leading cause of death in the United States is cancer and more than one million Americans are diagnosed with cancer each year, with this number likely to increase as the population ages. There remains a need for effective therapeutics with improved safety profiles, and promising results can be obtained through targeting receptors which are highly expressed on specific cancers. Vasoactive Intestinal Peptide (VIP) is a 28 amino-acid peptide hormone and one of several small neuropeptides that can function as autocrine growth factors. VIP mediates a variety of physiological responses and has been shown to exert stimulating and trophic effects on neoplastic cells inducing its own receptors by feedback mechanisms. Studies have shown that VIP receptors are present in many epithelial cancers including breast, colon, non-small cell lung carcinoma, and pancreatic and prostate cancers. Work by NIH scientists and their collaborators has shown that VIP receptor antagonists such as the lipophilic VIP antagonist SNH inhibit the growth of cancer cell lines in vitro and in vivo and potentiate the cytotoxicity of chemotherapeutic drugs. For example, results have shown that SNH and taxol are synergistic at inhibiting breast cell cancer growth and can potentiate the cytotoxicity of taxol in an in vivo human xenograft breast cancer mouse model.
Combination therapy using these agents may therefore greatly enhance the response rate of different cancers to these drugs and may significantly reduce side effects by permitting a lower therapeutic dose to be administered. Available for licensing are compositions of matter and methods of use of VIP receptor antagonists.
