Abstract:
The present invention refers to the employment of pharmaceutical compositions of snake venom glands secreted peptides, particularly from Bothrops jararaca, EVASINS, and analogous and derivatives compounds, and associated products, as modulating agents of the acetylcholine receptors. The pharmaceutical compositions of the present invention are characterized by acting as agonist, partial agonist, antagonist or alosteric modulators of the acetylcholine receptors. The pharmaceutical compostions of EVASINS also refer to the use of these compounds to protect the acetycholine receptors against the action of toxins, such as the phylantotoxins or cembranoids isolated from the coral or tobacco, or also spider toxins. The pharmaceutical compositions of EVASINS are characterized by the ability to prevent the binding of the cocaine to the acetylcholine receptors. The pharmaceutical compostions of EVASINS and their structural and/or conformational analogues characterized by the employment of EVASINS and their respective analogues and derivatives refer to the use as molecular models for the development of drugs and/or pharmaceutical compositions based on peptidic and/or non-peptidic compounds for the use in the diagnosis, prevention, study and treatment of diseases associated with the cholinergic receptors disfunctions. The pharmaceutical compositions of the mentioned EVASINS, analogues and derivatives included into cyclodextrins and derivatives, of the present patent show an increase of the biodisponibility, duration and/or efficacy of the modulating effects on the acetylcholine receptors once inoculated by different administration routes such as oral, intravenous, intramuscle, nasal, subcutaneous, transdermic, as non-limiting examples.
Abstract:
The present invention patent refers to the isolation and purification of peptides secreted by serpent venom glands, specifically Bothrops jararaca; to the peptide thus obtained, as well as to the production procedures by genetic engineering techniques in procaryotic and eukaryotic systems; to the engineered peptide thus obtained; to the production of said peptide by chemical synthesis, as well as to the peptide resulting from this chemical processing. It also refers to the utilization of said peptides, obtained by different procedures, in distinct pharmaceutical compositions, and introduced into the organism by a variety of means, in order for them to act as inhibitors of vasopeptidases, and consequently reduce systemic arterial blood pressure, and show local vasodilating action.

Abstract:
The present invention is characterized by the process of preparation of pharmaceutical compositions for the development of applications of the Evasins and their structural and/or conformational analogues in chronic-degenerative diseases. It s further characterized by the process of preparation of pharmaceutical compositions and related products of the Evasins peptides and their structural and/or conformational analogues in using the cyclodextrins, its derivatives, liposomes and biodegradable polymers and/or mixture of these systems.The present invention is also characterized by the identification of new biochemical and physio-pharmacological mechanisms not related to the effects on the bradykinin metabolism and angiotensin II formation, which contributes for the mechanism of action of these peptides in chronic-degenerative disorders. In the state-of-art no application was found which uses the Evasins and their analogues included in the cyclodextrins, liposomes, the biodegradable polimers and their derivatives, for the study and treatment of hypertension or other cardiovascular or chronic-degenerative diseases. This characterizes the present invention as a new and more efficient alternative for the study and treatment of these pathologies and their complications.It is further characterized by the increased efficacy of these peptides and their analogues included in cyclodextrins, when administered to rats. This characterizes an increased biodisponibility of these peptides and their analogues using the compositions of the present invention.
