UNITED STATES (OBSERVATORY NEWS) — It has been revealed that Swiss and British researchers have modified sugar molecules so that they are capable, by simple contact, of destroying viruses without toxicity to humans. Therefore, it is said that this method may be applied, for example, to the new coronavirus in China.
Also, according to recent information, it is said that so-called “virus killer” substances, such as bleach (bleach in English – chlorine in Albanian – candeggina in Italian), destroy the viruses by simple contact, but they cannot be applied to human body without causing serious damage, the University of Geneva (UNIGE) noted in a statement.
On the other hand, most of today’s antiviral drugs work by inhibiting the growth of viruses, but are unable to destroy them.
“To overcome these two obstacles and to be able to effectively fight viral infections, we found a completely different angle of attack,” said Caroline Tapparel Vu, a professor at the UNIGE Department of Microbiology and Molecular Medicine. , who led the research effort with Francesco Stellacci, a professor in the faculty of engineering sciences and techniques of the Lausanne Federal Polytechnic School (EPFL).
It should be noted that Swiss researchers had previously produced a gold-based antiviral. Applying the same concept, they have now managed to develop an antiviral using natural glucose derivatives, called cyclodextrins, according to an article published in the journal Science Advances, transmits albinfo.ch.
“The advantages of cyclodextrins are many: even more biocompatible than gold, and easier to use. They do not cause a resistance mechanism and are not toxic, “said Samuel Jones, a researcher at the University of Manchester, who was quoted by a UNIGE press release as saying.
“Moreover, cyclodextrins are already widely used, especially in the food industry, which would facilitate the marketing of pharmaceutical treatments using simple contact,” said Valeria Cagno of UNIGE.
With simple touch
What should be emphasized in this study is that modified sugar molecules attract viruses before irreversibly inactivating them. By disrupting the outer layer of the virus, they manage to destroy infectious particles by simple contact, rather than blocking only the growth of the virus.
Therefore, this mechanism seems to work regardless of the virus in question. Scientists have been able to demonstrate this in viruses responsible for respiratory infections and herpes.
It is worth noting that Cyclodextrins can be administered as a cream, gel or nasal spray.
Hope against epidemics
Regarding the development of new broad-spectrum antivirals is considered essential, especially to treat the most destructive or emerging viruses against which there is no treatment and may cause pandemics.
It is said that this composition, according to the authors, may have a global impact. The compound could also be effective against emerging new viruses, the coronavirus that started in China and spread overseas, risking a pandemic.
