Maribel Guerra Vallespi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20140206621
    Abstract: This invention describes a method for treating cancer by increasing the nuclear localization of the COMMD1 protein, which is associated with decreasing or blocking the proliferation of the cancer cell. The invention is also related to the use of agents that increase nuclear localization of the COMMD1 protein, in the manufacture of a medicament for cancer therapy. These agents can be peptides or proteins, among other compounds. The invention is also related to the optimization of a peptide, coming from the sequence HARIKPTFRRLKWKKYKGKFW, to increase the nuclear localization of the protein COMMD, and thus, to increase the antitumor effect of this peptide.

  • Patent number: 8673313
    Abstract: The present invention relates to use of a new cell penetrating peptides (CPP) and in particular to the region 32-51 of protein Limulus antilipopolisacárido (LALF) and its analogous. This invention refers to compositions containing these peptides associated to biomolecules with therapeutics properties. This invention consist of compositions comprise the covalent fusion of biomolecules, between this human papillomavirus antigens (HPV) to these CPP for induce a potent immune cellular responses against HPV and HPV protein antigen-exhibiting cells including HPV-associated tumors. The referred compositions are applicable in the pharmaceutical industry as vaccine for therapeutic use in human.

  • Patent number: 8283324
    Abstract: The present invention is related to the development of peptides derived from the sequence HYRIKPTFRRLKWKYKGKFW (SEQ ID NO.: 13), showing amino acid substitutions, these peptides unable to bind to the lipopolysaccharides and bearing anti-tumoral and immunomodulatory capacities. These peptides alone or in combination are useful to treat cancer, and also in synergy with conventional therapies.

  • Patent number: 6632793
    Abstract: The present invention relates a novel immunological effect of one peptide from Limulus anti-LPS factor protein. The immunological effect are, (1) Induce an antiviral state in both the Hep-2 and MDBK cell lines, (2) Supernatant from human mononuclear cells stimulated with peptide Limulus anti-LPS factor (LALF) is able to induce antiviral effect on Hep-2 cell line by mean of IFN-&ggr; (3) LALF peptide is able to modulate the immune response in vitro and in vivo. The present invention can be used in therapeutic and/or prophylactic treatment regimens of humans and animals to enhance their immune responses, without stimulating the production of certain biochemical mediators (e.g., TNF-&agr;) that can cause detrimental effects, such as fever and inflammation.
