20090005294 | Peptides for the Treatment of Cancer Associated with the Human Papilloma Virus (HPV) and Other Epithelial Tumors - This invention is related to the Molecular Pharmacology field and especially to the development of peptides useful for treating epithelial tumors and mainly those associated to oncogenic types of HPVs. The main objective of this invention is to identify peptides whose structure permits to block the Casein Kinase II (CKII) phosphorylation domain by direct interaction with such a site. In the present invention it is shown eleven cyclic peptides with different aminoacid sequences which inhibit the CKII phosphorylation in vitro, exhibit cytotoxicity on HPV-16 transformed cells (CaSki) and also increase the sensitivity of these cells to the cytostatic effect of interferon (IFN). Furthermore, the invention relates to the use of these peptides conjugated or fused to other peptides and chemical compounds which penetrates into cells as well as with the use of both peptide and chemical mimetic molecules. | 01-01-2009 |
20090136511 | Interleukin-15 Antagonist Peptide - Current invention is related to the molecular pharmacology branch particularly to a peptide belonging to the Interleukin-15 sequence (IL-15) which is able to inhibit IL-15 biological activity, analogues or mimetic of such peptides. In the current invention it is shown that the peptide inhibits both IL-15-induced T cells proliferation upon binding to the IL15 receptor α subunit (IL15Rα) and TNFα-mediated apoptosis. | 05-28-2009 |
20090221508 | IMMUNOMODULATORY AND ANTI-TUMOUR PEPTIDES - The present invention is related to the development of peptides derived from the sequence HYRIKPTFRRLKWKKYKGKFW, showing aminoacids substitutions, these peptides unable to bind to the lipopolysaccharide 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. | 09-03-2009 |
20100055118 | Peptidic Growth Hormone Secretagogues Analog Compounds and Preparations Thereof - Peptidic chemical compounds obtained by in silico molecular modelling, having a structure that enables them to perform the same functions of peptidic growth hormone secretagogues. The invention also comprises the preparations containing such compounds and the use in medicines, food additives, nutritional supplements or other formulations of human or animal use. | 03-04-2010 |
20100273702 | CHIMERICAL PEPTIDIC MOLECULES WITH ANTIVIRAL PROPERTIES AGAINST THE VIRUSES OF THE FLAVIVIRIDAE FAMILY - The present invention is relative to chimerical peptides, whose primary structure holds at least one segment which inhibits the activation of the NS3 protease of a virus from the Flaviviridae family, they also contain a cell penetrating segment and they are capable of inhibiting or attenuate the viral infection. This invention is also relative to pharmaceutical compounds which contain these chimerical peptides for the prevention and/or treatment of the infection caused by a virus of the Flaviviridae family. | 10-28-2010 |
20110212105 | METHOD TO BLOCK THE INFECTION BY FLAVIVIRUSES, MOLECULES AND USES - The present invention is related to a method for blocking the infection of cells by dengue virus, based on interfering the direct interaction of the viral envelope protein with a cellular receptor or its indirect interaction with said cellular receptor through a carrier protein, as well as related uses; wherein said cellular receptor is the alpha-2 macroglobulin receptor, also known as the low density receptor-related protein or as CD91, and said carrier protein is human alpha-2 macroglobulin. | 09-01-2011 |
20110250196 | PHARMACEUTICAL COMPOSITION USING GONADOTROPIN - RELEASING HORMONE (GNRH) COMBINED VARIANTS AS IMMUNOGEN - A pharmaceutical composition using natural gonadotropin-releasing hormone (GnRH), and/or some of its mimetic peptides, indistinctly bound by its amino or carboxyl extremes to a carrier molecule; in one case by its carboxyl extreme and in the other case by the amino terminal extreme, thus eliciting a faster and more potent immunological response against the endogenous GnRH hormone. This finally leads to the ablation of the GnRH and consequently of the rest of the involved hormones in the stream GnRH/LH-FSH/Testosterone-(estrogens). An advantage of this formulation consists on facilitating the exposition to the immune system of a greater number of epitopes of the GnRH or its mimetics, minimizing thus the steric hindrance produced by the carriers. This invention has a direct application in the castration of pets and animals of economic interest, in the control of human fertility as well as in the treatment of hormone-sensitive tumors, such as that of the prostate, the breast, ovary, the endometry, testicles, hypophysis, salivary glands and other kinds of human tumors. | 10-13-2011 |
20110251140 | PEPTIDE ANTAGONIST OF INTERLEUKIN-15 ACTIVITY - The present invention is related to the field of molecular immunology, particularly to a peptide derived from the sequence of interleukine-15 (IL-15), wherein said peptide was optimized to inhibit the biological activity of this molecule. In the present invention, it is shown that this peptide inhibits IL-15-induced T cell proliferation, Tumor Necrosis Factor α (TNFα) induction and the expression of IL-8 and IL-6 by the IL-15 receptor a subunit (IL-15Rα), all these effects mediated by the binding of the peptide to the IL-15Rα. The invention is also related to the use of the peptide to treat pathologies where the abnormal expression of IL-15 or IL-15Rα is related to the course of the disease, such as rheumatoid arthritis (RA) and prostate cancer. | 10-13-2011 |
20120135021 | CELL PENETRATING PEPTIDES AND ITS USE FUSED TO BIOMOLECULES WITH THERAPEUTIC ACTION - The present invention relates to use of a new cell penetrating peptides (CPP) and in particular to the region 32-51 of protein | 05-31-2012 |
