Malaria remains one of the deadliest diseases in many parts of the world.
Current treatments often require several doses over many days, which can be hard to follow.
Scientists at the University of Dundee have discovered a promising drug-like molecule called cabamiquine.
In early clinical trials in Africa, the drug had a good safety profile.
It was tested in both adults and adolescents.
When combined with another drug called pyronaridine, it worked effectively against the infection.
Researchers hope this combination could make malaria treatment shorter and simpler.
However, more studies are still needed before it can be widely used.
