    Summary: Nitric Oxide Donors: Biomedical Applications and Perspectives presents the current state of art, challenges and innovations in the design of therapeutics nitric oxide donors with great impact in several aspects of human physiology and pathophysiology. Although considerable innovative progress has been achieved using Nitric Oxide donors in biomedical applications, certain drawbacks still need to be overcome to successfully translate these research innovations into clinical applications. This book encompasses several topics on nitric oxide such as its sources and biological properties; its performance in the cardiovascular and neurologic systems, in the human skin and its application in the treatment of neglected diseases, neurodegenerative disorders, and cancer. Additionally, it covers its role in inflammation and immunity, penile erection function, photodynamic therapy, antimicrobial activities. It also discusses the future of nitric oxide donors in combination with other therapeutic drugs, in implantable sensors, and nitric oxide releasing hydrogels and medical devices for topical applications. The book is a valuable source for researchers on different areas of biomedical field who are interested in the improvements that these molecules can make in the treatment of several conditions.

    Lipoic acid has recently been found to stimulate prostaglandin biosynthesis by sheep vesicular gland microsomes (Marnett, L. J., and Wilcox, C. L. (1977). Biochim. Biophys. Acta 487, 222). The increase in oxygenated products is predominantly in the formation of prostaglandin F and its structure has been verified by gas chromatography-mass spectrometry. Endoperoxide trapping experiments employing reduced glutathione show that the conversion of prostaglandin H to prostaglandin F is slow in lipoate containing incubation mixtures. Therefore, the net effect of the addition of lipoic acid to vesicular gland microsomes is the stimulation of prostaglandin endoperoxide biosynthesis. Further experiments reveal that the reduction of prostaglandin H to prostaglandin F by lipoate is nonenzymatic and occurs after the termination of biosynthesis in the work-up mixture. The reduction takes place preferentially in the organic phase of a Folch extract (chloroform-methanol-2% formic acid 8:4:3). Authentic prostaglandin H2 is reduced by lipoic acid to prostaglandin F 2alpha in high yield under these conditions.
