Zusammenfassung: | The present invention refers to a process of preparation of compounds of AT1 receptor antagonists and Angiotensin (1-7), for example, Angiotensin-(1-7) losartanate and analogues thereof, and/or mixtures of these systems, pharmaceutical compositions thereof and use of their derivative products. It its further characterized by the use of cyclodextrins and derivatives thereof for the micro-encapsulation of compounds, for example, Angiotensin (1-7) losartanate, liposomes and biodegradable polymers and/or mixtures of these systems and/or derivative products for the obtainment of nano- or microparticles as controlled or sustained release devices of Ang-(1-7) losartanate and analogues and/or mixtures thereof. Another characteristic of the compounds claimed in the present application is the use thereof as agents for treating or preventing hypertension, cardiovascular diseases, heart hypertrophy, heart failure, coronary diseases, such as angina pectoris, endothelial disorder or endothelial lesions, as a consequence, for example, of atherosclerosis processes or in association with diabetes mellitus. The compounds may also be used in the study and therapeutic of cardiovascular, renal, reproductive, dermatological, neoplastic, blood and cerebral diseases, and when formulated in controlled release systems, encapsulated or not in cyclodextrins, for use in stent, with a view to modulate the growth of the neointima after catheterization procedures.
La présente invention concerne un procédé de préparation de composés d'antagonistes des récepteurs AT1 avec l'angiotensine-(1-7), par exemple de losartanate d'angiotensine-(1-7) et d'analogues de celui-ci, et/ou de mélanges de ces systèmes, des compositions pharmaceutiques les incorporant et l'utilisation de leurs produits dérivés. Elle concerne en outre l'utilisation de cyclodextrines et de dérivés de celles-ci pour la microencapsulation de composés, par exemple de losartanate d'angiotensine-(1-7), des liposomes et des polymères biodégradables et/ou des mélanges et/ou des produits dérivés de ces systèmes pour l'obtention de nano- ou microparticules servant de dispositifs de libération contrôlée ou prolongée de losartanate d'angiotensine-(1-7) et d'analogues de celui-ci et/ou de mélanges de ces derniers. Une autre caractéristique des composés revendiqués par la présente invention est leur utilisation comme agents destinés au traitement ou à la prévention de l'hypertension, des maladies cardiovasculaires, de l'hypertrophie cardi |
