摘要:
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.
摘要:
The present invention deals with recombinant polypeptide molecules related to antibodies, that specifically recognize the human Vascular Endothelial Growth Factor A (VEGF-A), and interfere with its in vitro stimulatory effects and pro-angiogenic activity in vivo . These recombinant polypeptide molecules affect proliferation of human endothelial cells in vitro, subcutaneous angiogenesis in mice induced by Matrigel pellets that contain VEGF-A and the growth of human tumors transplanted in nude athymic mice. Several of these moleculas prevent choroideal neovascularization in a non human primate experimental model. These molecules can be employed for passive immunotherapy in pathological entities which have in its base an abnormal increase in blood vessels, as: age-related macular degeneration (wet variant), cancer and its metastases, neovascular glaucoma, diabetic and newborn retinopathies, acute and chronic inflammatory processes, infectious diseases, autoimmune diseases, organ transplant rejection, hemangioma, angiofibroma, and others.

摘要:
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.
摘要:
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.
摘要:
Use of chemical compounds obtained in silico for the preparation of pharmaceutical compositions to attenuate or inhibit Dengue virus infection. Particularly, through the interference or the modulation of several stages of viral replication cycle related with the entry of virus into host cells and the assembly of mature progeny virions. The invention also comprises the use of such pharmaceutical compositions for prophylactic and/or therapeutic treatment of infection caused by all four serotypes of Dengue virus and other flaviviruses.
摘要:
The present invention discloses structurally constrained synthetic peptides that have been optimized for the formation of a beta hairpin structure. Said peptides are able to inhibit or attenuate Dengue virus (DENV) infections. The invention also discloses pharmaceutical compositions containing these synthetic peptides, which are useful for the prevention and/or treatment of DENV-caused infections. Likewise, the invention disclosed a method for treating infections caused by this virus.
