Abstract: The present invention comprises cyclic peptides bearing antitumor and antiangiogenic properties, as well as their corresponding pharmaceutically-suitable salts and also pharmaceutical compositions containing it. These cyclic peptides are used to prepare medicines for human and/or veterinary therapeutics, and additionally in diagnosis. These compounds can be used to detect, monitor and/or control a range of cellular proliferation-related disorders, such as oncological diseases and undesired angiogenesis. Moreover, they can be included as part of controlled release systems, and used more precisely in the field of nanobiotechnology, either because of their self-assembly capacity or as part of other systems.

Abstract: 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.

Abstract: The present invention is related to the obtaining of chimeric chains coding for proteins capable of inducing, in the recipient, a serotype-specific and protective humoral immune response against the infection by the Dengue virus, thus eliminating the effects of the serotype-nonespecific viral immunoenhancement that causes hemorrhagies and clinical complications described for this kind of pathology. These chimeric chains of nucleic acids are composed by the specific combination of fragments belonging to the gene of a mutated protein from Neisseria meningitidis with dehydrogenase activity and fragments that codify for a region of the envelope (E) protein from the Dengue virus which, when inserted to an expression vector, give rise to chimeric proteins with particular properties. The resultant chimeric molecules from this invention are applicable to the pharmaceutical industry for the obtaining of vaccine preparations and diagnostic means of high serotype-specificity to be used in humans.

Abstract: 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.
