Abstract: The present invention relates to novel derivatives of hydrophilic bioactive peptides which have been modified by introducing a lipophilic substituent through esterification of the free carboxylic group(s) of the peptide with an aliphatic alcohol. The present invention also refers to a simple, fast and effective process for the preparation of amphiphilic derivatives of peptides. It also refers to pharmaceutical compositions for the controlled release and delivery of these pharmacologically active peptides.

Abstract: The present invention relates to the peptide (arg0) n-angiotensin-(1-7) [(arg0) n-Ang-(1-7)], where n is 1 to 10 (Xaa-Asp-Arg-Val-Tyr-Ile-His-Pro; SEQ ID NO:1 where Xaa represents 1 to 10 L-Arg residues), which is produced by inserting at least one arginine amino acid at the amino terminal position of Ang-(1-7), as well as pharmaceutical compositions containing this peptide and the use thereof for the treatment or prevention of diseases or disorders that are due or associated with reduced nitric oxide production. Non-limiting examples of these diseases or disorders are cardiopulmonary and liver diseases, vascular disorders, metabolic disorders, neural disorders, genito-urinary tract disorders, skeletal muscle disorders, kidney disorders, skin disorders, alopecia or tumors.

Abstract: The present invention discloses formulations for the treatment and prevention of alopecia; the formulations comprise angiotensin-(1-7) and/or their analogues, encapsulated in ultradeformable vesicles prepared from specific combinations of phospholipids and surfactants, which confer efficacy to topical application in the control of hair growth, which indicates their great potential for the prevention and treatment of alopecia. The invention also describes formulations containing A779 Mas receptor antagonist of angiotensin-(1-7) and/or their analogues and their use in inhibiting hair growth.

Abstract: The present invention relates to a pharmaceutical composition for treating visceral leishmaniasis, characterized in that it comprises the association of conventional liposomes and prolonged-circulation liposomes with a leishmanicidal-drug delivery system. Said composition may be used in the preparation of a medicinal product for treating leishmaniasis and may be administered intramuscularly, subcutaneously, intraperitoneally or intravenously. The use of this system enables the drug efficiently to reach all sites infected by the parasite, the pegylated liposomes promoting more effective targeting of the leishmanicidal drugs on the bone marrow and spleen, whilst the conventional liposomes contribute to the targeting of the drug on the liver.

Abstract: The present invention relates to the use of Ang-(1-7) and/or Ang-(1-7) receptor agonist and/or Ang (1-7) analogue in treating/restoring erectile dysfunction.

Abstract: Inclusion compounds consisting of certain Angiotensin II AT1 receptors antagonist and cyclodextrins are described. These inclusion compounds are useful in the treatment of hypertension.

Abstract: Preparation of AT1 receptors antagonists formulations using the cyclodextrins, their derivatives and/or biodegradable polymers for the treatment of arterial hypertension, other cardiovascular disease and their complications. Until now, no applications using the AT11 receptor antagonists and cyclodextrins or derivatives and/or biodegradable polymers for the treatment of arterial hypertension, other cardiovascular diseases and their complications, was found in the technical state of art. The present invention is characterized by the combination of two different technologies: one is the molecular encapsulation of AT11 receptor antagonists in cyclodextrins and the other is the microencapsulation in biodegradable polymers. It also comprises the increase of the effectiveness of the AT11 receptor antagonists as well as an increase in their bio-availability.

Abstract: The present invention is characterized by the use of Mas G-protein-coupled receptor agonists and antagonists as apoptotic activity modulators for study, prevention and treatment of diseases. It is further characterized by the use of Mas G-protein-coupled receptor agonist and antagonists for modulation of the apoptotic activity involving alterations in the activity of the protein kinase B/Akt. Another characteristic of the invention is the use of Mas G-protein-coupled receptor agonists and antagonists, including the Ang-(1-7) peptide and its analogues, agonists and antagonists, either peptidic or non-peptidic, as modulators of apoptotic activity for study, prevention and treatment of degenerative diseases of organs and systems, as an auxiliary measure for organs transplantation, treatment with embryonic, non-embryonic stem cells, re-implantation of organs and tissues and other treatments that need temporary or chronic reduction of the apoptotic activity, not limitative.
