Cholesterol depletion

Viroblock’s unique cholesterol depletion technology

Viroblock’s proprietary antiviral technology deactivates the entire class of enveloped viruses, which represents 90% of all human viral pathogens (e.g., Influenza, SARS, Herpes, HIV, etc.).

Viroblock has a strong IP position based on a very simple technology. Specifically, Viroblock technology uses a combination of non-phospholipids and cyclodextrin to inactivate (kill) enveloped viruses.

When the non-phospholipids and cyclodextrins are appropriately formulated they have strong anti-viral properties. Cyclodextrins are similarly well known and are frequently used odor control products or in pharmaceuticals as non-active ingredients. When appropriately formulated the non-phospholipids and cyclodextrins have strong anti-viral properties.

Viroblock technology targets cholesterol and not a gene product, so Viroblock products are broad spectrum (eg. all enveloped viruses tested so far are susceptible) and do not create resistance. This means that multiple pathogenic viruses such as Influenza H1N1 and H5N1, RSV, Herpes Simplex Virus, HIV, SARS, etc., can all be killed by Viroblock products.

Finally, cholesterol depletion is extremely fast. This is opening the way to making products that can kill air borne viruses during the fraction of a second it takes for them to pass through a filter.

Viroblock has developed a unique anti-microbial fabric based on its proprietary cholesterol sequestration technology. Capable of inactivating H5N1 and other enveloped viruses on pass through air, the fabric opens a new chapter in air filtration. Unlike regular face-masks (e.g., N95 or FFP2) that have only a limited ability to remove enveloped viruses from pass through air, the new Viroblock respiratory mask traps and kills 99.9995% of H1N1 on pass through air.

Furthermore, a minute amount of an anti-microbial agent has been added to Viroblock's formulation, which provides this technology with antibacterial and anti fungal properties. Thus, bacteria or fungi passively trapped in the mask are also inactivated, a self-sanitizing aspect of crucial importance for infection control.
