Research carried out in part by an artificially-intelligent (AI)’robot scientist’ has found that a common ingredient of toothpaste could be developed to fight drug-resistant strains of malaria.
In a study in the journal Scientific Reports, scientists from Britain’s Cambridge University who used the AI robot to conduct high-throughput screening said the ingredient, triclosan, showed the potential to interrupt malaria infections at two critical stages – in the liver and the blood.
Malaria kills around half a million people every year, the vast majority of them children in the poorest parts of Africa. The disease can be treated with a number of drugs, but resistance to these medicines is increasing, raising the risk that some strains may become untreatable in the future.
Because of this, the search for new medicines was becoming increasingly urgent, said Steve Oliver of Cambridge University’s biochemistry department, who co-led the work with Elizabeth Bilsland.
After being transferred into a new host via a mosquito bite, malaria parasites work their way into the liver, where they mature and reproduce. They then move into red blood cells, multiply and spread around the body, causing fever and potentially life-threatening complications.
