Rutin, a flavonoid, may complement antivenom as an effective co-treatment for envenoming from Bothrops jaraca.
Researchers have found that rutin, an inexpensive, plant-based compound may protect envenomed mice from bleeding and inflammation problems, according to a study published in PLOS Neglected Tropical Diseases by Ana Teresa Azevedo Sachetto of Institute Butantan, São Paulo, Brazil.
Anti-venom can effectively treat the major manifestations of snakebites, however, there are no known therapies effective for common secondary complications. Venom toxins from Bothrops jaraca (lance-headed vipers) may trigger bleeding, disrupt oxidation reduction in cells, and inhibit the body's ability to stop bleeding. Researchers injected both venom and rutin into a group of mice, then analyzed blood and tissue samples to understand what effect(s) if any, the rutin had on pathophysiological events triggered by Bothrops jararaca venom.
The mechanisms of clinical complications in patients bitten by B. jaraca snakes are not well understood and antivenom therapy is limited in its ability to treat the full array of complications that may occur following a snakebite. Future studies will be necessary to understand rutin activity once venom has initiated pathophysiological events, as well the therapeutic effects of rutin delivered with antivenom. According to the authors, the research "indicates that rutin has a great potential as an ancillary drug in concert with antivenom therapy to treat snakebites, particularly in countries where antivenom availability is scarce."

Researchers have developed an artificial enzymatic pathway for synthesizing isoprenoids, or terpenes, in E. coli. This shorter, more efficient, cost-effective and customizable pathway transforms E. coli into a factory that can produce terpenes for use in everything from cancer drugs to biofuels.READ MORE
