Melbourne researchers have shown that a century-old topical antiseptic used to treat wounds and \u2018sleeping sickness\u2019 in Australian soldiers in World War One could activate the immune system to protect against viral infection, and may prove key in the fight against antibiotic resistance.<\/span><\/p>\n\n\n\n

A study by the team of scientists at Hudson Institute of Medical Research in Clayton, has shown that a century-old antiseptic called Acriflavine, made from coal tar, protects against the common cold. The findings of the study, led by Dr Michael Gantier<\/a> and Dr Genevieve Pepin in the Nucleic Acids and Innate Immunity Group at Hudson Institute, have just been published in the prestigious journal, Nucleic Acids Research<\/em>.<\/a><\/p>\n\n\n\n

Acriflavine triggers powerful immune response<\/h2>\n\n\n\n

The team believes the way Acriflavine activates the immune system could also offer a useful tool in the fight against superbug resistance, and viral pandemics.<\/p>\n\n\n\n

In the study, the team showed that pre-treating human lung cells with Acriflavine protected the cells against rhinovirus infection (the common cold) by triggering an anti-viral immune response.<\/p>\n\n\n\n

Dr Gantier, head of the Research Group in Hudson Institute\u2019s Centre for Innate Immunity and Infectious Diseases, says Acriflavine was used to treat everything from gonorrhoea to urinary infections prior to World War Two, but a whole picture of its mechanism of action has evaded scientists \u2013 until now.<\/p>\n\n\n\n

\u201cAcriflavine was heavily used during World War One as a topical antiseptic to treat wounds. Early scientific literature notes its antibacterial qualities in test tubes, but its very effective action on the skin has never been fully defined,\u201d Dr Gantier said.<\/p>\n\n\n\n

\u201cWe have shown for the first time that Acriflavine binding to cellular DNA could activate the host immune system, unleashing a powerful immune response on a potentially broad range of bacteria.<\/p>\n\n\n\n

Double punch <\/h2>\n\n\n\n

\u201cThe effect is two-fold \u2013 Acriflavine directly affects the bacteria, and then you get the activation of the immune system through the \u2018STING\u2019 pathway, which helps to clear the infection,\u201d he said.<\/p>\n\n\n

Acriflavine (also known as Trypaflavine) was first identified as an antiseptic by German scientists in 1912[i]<\/a>. It was used by soldiers in the First World War to treat wounds and kill parasites that cause sleeping sickness. Australia\u2019s volunteer nurses in the Second World War also had acriflavine in their kits[ii]<\/a>.<\/p>\n\n\n\n

Acriflavine used before penicillin<\/h2>\n\n\n\n

Dr Genevieve Pepin, first author on the paper, says Acriflavine could one day offer a safeguard against drug resistance, and could be used during a viral outbreak to trigger a baseline immune response to an infection, such as SARS or influenza, in at-risk groups.<\/p>\n\n\n\n

\u201cAcriflavine was used in the first half of the 20th<\/sup> century as a topical antibacterial, before being supplanted by penicillin. Now, antibiotic resistant superbugs are a growing threat to human health,\u201d Dr Pepin said.<\/p>\n\n\n\n

\u201cOur study indicates that Acriflavine stimulates the host immune system, rather than simply killing bacteria, suggesting it wouldn\u2019t be as likely to drive mutations in bacteria \u2013 showing a safeguard against resistance and a potential alternative to current antibacterial drugs,\u201d she said.<\/p>\n\n\n\n

Potential to treat viral and bacterial infections<\/h2>\n\n\n\n

Next, the team will use pre-clinical models to test how well Acriflavine mobilises the immune system in more virulent strains of infection.<\/p>\n\n\n\n

Dr Gantier says Acriflavine, a drug that has largely been out of use for the last 50 years, is showing strong potential against viral and bacterial infections and their newest challenges in the 21st<\/sup> century.<\/p>\n\n\n\n
