A formulation of the high purity, pharmaceutical grade rose bengal drug substance of Provectus (abbreviated in the article as HP-RBf) killed a battery of G + bacteria, including drug resistant strains, at low concentrations of Within minutes under fluorescent lights, LEDs, and natural light, HP-RBf eradicated G + bacterial biofilms, including drug-resistant strains, The frequency with which G + bacteria spontaneously developed resistance to HP-RBf was extremely low, Based on the toxicity data from their research, HP-RBf may be feasible as an anti-infective drug for the treatment of skin and soft tissue infections (STBBIs) involving multidrug-resistant microbial invasion (MDR) of the skin, and based on whole genome sequencing and analysis of an HP-RBf resistant mutant generated, the antibacterial activity of HP-RBf under low darkness conditions t involve multiple cooperative action mechanisms.

Dominic Rodrigues, Vice Chairman of the Company’s Board of Directors, said: “We are grateful to Dr Kurosu and his team for their scientific research.

Dr. Kurosu’s work also strongly complements research on antipathogens carried out by other Provectus collaborators.

Mr. Rodrigues added, “Provectus’ pharmaceutical grade rose bengal drug substance is produced through a proprietary 21st century manufacturing process, using quality principles from design under good manufacturing practice. commercial scale, which systematically synthesizes the company’s rose bengal molecule. The Provectus process primarily prevents the formation of substance-bound contaminants and other contaminants found in commercial grade rose bengal, which is made primarily using the 19th century Gnehm process.
