Abstract: The present description relates to methods of treatment and pharmaceutical compositions comprising a Nitric Oxide Synthase-inducer peptide, PnPP-19. Although usable for other purposes, the composition comprising PnPP-19 is useful for treating and/or preventing eye diseases related to intraocular hypertension and/or optic nerve degeneration, such as glaucoma.

Abstract: Synthetic peptides that are modulators of smooth muscle tone and compositions thereof, including pharmaceutical compositions containing a peptide, make it possible to treat indications in those in need of modulation of the smooth muscle tone, including, for example, benign prostate hyperplasia (BPH), Raynaud's syndrome, Pulmonary Arterial hypertension (PAH), systemic arterial hypertension (SAH) and hyper-reactivity of airways associated with asthma, COPD, pulmonary fibrosis, silicosis, allergic bronchopulmonary aspergillosis, hereditary angioedema, and neonatal hypoxemic respiratory failure. Although makeable in other ways, the synthetic peptides are makeable by recombinant methods or synthetic pathways.

Abstract: The present invention relates to smooth muscle tone modulating synthetic peptides. It also refers to pharmaceutical compositions containing such peptides and to the uses thereof in the treatment of disturbances in which the modulation of the smooth muscle tone is beneficial.

Abstract: The present invention relates to a synthetic peptide of 19 amino acids, called PnTx(19), constituted from the sequence of the native toxin PnTx2-6 of the Phoneutria nigriventer spider. It also relates to pharmaceutical compositions containing such a peptide and to the use thereof in the treatment of erectile dysfunction and/or in potentiating the erectile function.

Abstract: The present invention concerns a method for male erectile function potentiating by means of toxin Tx2-6 from the spider Phoneufria nigriventer.

Abstract: The present invention provides isoformes from a peptide family belonging to South American scorpion Tityus serrulatus that acts as hypotensive agents by potentiating Bradykinin and, therefore, can be used as anti-hypertensive drugs. A peptide was firstly isolated from Tityus serrulatus venom and showed a strong and long-lasted hypotensive activity when tested in rats. This peptide was first named TsHpt-I (Tityus serrulatus Hypotensin-I). Also, three more highly similar isoformes were identified and revealed a peptide family with very close primary structure. They were named TsHpt-II, TsHpt-III and TsHpt-IV.
