Researchers have discovered two new
chemical compounds that can speedily kill the Plasmodium parasites that cause
malaria.
Around 3 million deaths are
caused by Malaria every year, and it is dominant in tropical regions of Africa,
Asia, and Latin America.
How this finding can help?
Although anti-malarial drugs are
already available but there is need to develop more efficient drug to counter
increasing resistance of Plasmodium parasite.
The newly identified treatment has been
found so effective that it can kill 90% of the parasites in just 3 hours and
all those tested in laboratory samples of infected human blood cells, within 12
hours.
How does it work?
These molecules interfere with an
important stage of the parasite’s growth cycle and use this effect to kill
them. They affect Plasmodium falciparum’s ability to carry out transcription
(the biological process whereby the DNA sequence in a gene is copied into RNA).
These compounds kill the parasite
during the long period of its complex life cycle while it resides in the
blood-stream. This is an advancement over the majority of anti-malarial drugs,
whose action is limited to shorter stages of Plasmodium’s life cycle.
