Prostacyclin and Its Stable Analogue, Iloprost


Book Description

Ten years after the discovery of prostacyclin, our knowledge of its biochemical mode of action, pharmacological properties, pathophysiological significance and therapeutic applications is ever expanding. Prostacyclin is both complex and unique as demonstrated by its unusual feature of being chemically and meta bolically unstable when compared to other prostanoids and known amine or peptide mediators. Although physiologically essential, the chemical instability of prostacyclin poses a serious drawback in laboratory and clinical studies. It is one of the genuine objectives of pharmaceutical research to supply synthetic compounds which overcome the inherent drawbacks - considering investigational and therapeutic use - of endogenous compounds. Whereas metabolic instability in certain cases could be of advantage, chemical instability definitely is not. With Iloprost, a molecule has been designed which - according to all data so far available - pertains high receptor affinity, metabolic instability (clinically this equates with a fine control of Iloprost's effects) while chemical stability has been achieved. By virtue of these characteristics Iloprost can be considered as one step towards specific interaction within the arachidonic acid cascade, namely the prostacyclin receptor. The aim of the symposium was to provide a critical experimental appraisal concerning the biochemical mode of action and pharmacological properties of prostacyclin and Iloprost.

Fluorine and Health


Book Description

Fluorine and Health presents a critical multidisciplinary overview on the contribution of fluorinated compounds to resolve the important global issue of medicinal monitoring and health care. The involved subjects are organized in three thematic parts devoted to Molecular Imaging, Biomedical Materials and Pharmaceuticals. Initially the key-position of partially fluorinated low molecular weight compounds labelled either with the natural 19F-isotope for Magnetic Resonance Imaging (MRI) or labelled with the radioactive [18F]-isotope for Positron Emission Tomography (PET) is highlighted. Both non-invasive methods belong to the most challenging in vivo imaging techniques in oncology, neurology and in cardiology for the diagnosis of diseases having the highest mortality in the industrialized countries. The manifold facets of fluorinated biomaterials range from inorganic ceramics to perfluorinated organic molecules. Liquid perfluorocarbons are suitable for oxygen transport and as potential respiratory gas carriers, while fluorinated polymers are connected to the pathology of blood vessels. Another important issue concerns the application of highly fluorinated liquids in ophthalmology. Moreover, fluorine is an essential trace element in bone mineral, dentine and tooth enamel and is applied for the prophylaxis and treatment of dental caries. The various origins of human exposure to fluoride species is detailed to promote a better understanding of the effect of fluoride species on living organisms.Medicinally relevant fluorinated molecules and their interactions with native proteins are the main focus of the third part. New molecules fluorinated in strategic position are crucial for the development of pharmaceuticals with desired action and optimal pharmacological profile. Among the hundreds of marketed active drug components there are more than 150 fluorinated compounds. The chapters will illustrate how the presence of fluorine atoms alters properties of bioactive compounds at various biochemical steps, and possibly facilitate its emergence as pharmaceuticals. Finally the synthetic potential of a fluorinase, the first C-F bond forming enzyme, is summarized. - New approach of topics involving chemistry, biology and medicinal techniques - Transdisciplinar papers on fluoride products - Importance of fluoride products in health - Updated data on specific topics




The Endothelium


Book Description

The endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells. The endothelium is a major player in the control of blood fluidity, platelet aggregation and vascular tone, a major actor in the regulation of immunology, inflammation and angiogenesis, and an important metabolizing and an endocrine organ. Endothelial cells controls vascular tone, and thereby blood flow, by synthesizing and releasing relaxing and contracting factors such as nitric oxide, metabolites of arachidonic acid via the cyclooxygenases, lipoxygenases and cytochrome P450 pathways, various peptides (endothelin, urotensin, CNP, adrenomedullin, etc.), adenosine, purines, reactive oxygen species and so on. Additionally, endothelial ectoenzymes are required steps in the generation of vasoactive hormones such as angiotensin II. An endothelial dysfunction linked to an imbalance in the synthesis and/or the release of these various endothelial factors may explain the initiation of cardiovascular pathologies (from hypertension to atherosclerosis) or their development and perpetuation.
