Study of the biological activity of novel synthetic compounds with antiviral properties against human rhinoviruses.
Picornaviridae represent a very large family of small RNA viruses, some of which are the cause of important human and animal diseases. Since no specific therapy against any of these viruses currently exists, palliative symptomatic treatments are employed. The early steps of the picornavirus replicative cycle seem to be privileged targets for some antiviral compounds like disoxaril and pirodavir...
متن کاملAntiviral activity of garlic extract on Influenza virus
Abstract: Influenza virus is the most important cause of annual morbidities and mortalities worldwide with numerous antigenic drifts and shifts. Inaccessibility to effective drugs and vaccines has made world health authorities to be interested in traditional medicine in order to prevent spread of the infectious agent. Garlic is one of the most famous of all plants in human history. It has bee...
متن کاملStructural characteristics of human substantia nigra neuromelanin and synthetic dopamine melanins.
Neuromelanin (NM) is a complex polymer pigment found primarily in the dopaminergic neurons of the human substantia nigra. The structure of NM is only partially characterized, and its synthesis pathway remains unknown. We used nuclear magnetic and infrared spectroscopy to examine the structure of human NM isolated from the substantia nigra compared with synthetic dopamine melanins. Biochemical a...
متن کاملDifferential Antifungal Activity of Human and Cryptococcal Melanins with Structural Discrepancies
Melanin is a pigment found in all biological kingdoms, and plays a key role in protection against ultraviolet radiation, oxidizing agents, and ionizing radiation damage. Melanin exerts an antimicrobial activity against bacteria, fungi, and parasites. We demonstrated an antifungal activity of synthetic and human melanin against Candida sp. The members of the Cryptococcus neoformans and C. gattii...
متن کاملChemosorption of radiometals of interest to nuclear medicine by synthetic melanins.
INTRODUCTION Melanins are high-molecular-weight pigments that are ubiquitous in nature and can also be synthesized in the laboratory from a variety of precursors. Melanins possess numerous interesting physicochemical characteristics, including electromagnetic radiation absorption properties and ability to chelate metals. We have recently reported that melanin has remarkable ionizing-radiation-s...
