Malaria
is a primordial disease that has been affecting human race since their origin.
Albeit the parasite shows parallel divergence with hominids, it has evolved so
finely and shaped its genome to a great extent to invade, dodge and damage
hosts defence system. Small generation time, pressure to survive and grow under
adverse environmental conditions inside host, ability to disguise and escape
host immune system; help the parasite to succeed the evolutionary arms race.
Hence, malaria associated morbidity and mortality is a major public healthconcern especially for underdeveloped and developing countries of the globe.Though many malaria control and eradication strategies have been followed since
ages, but none of them are successful in an overall control program. In the absence
of a competent vaccine for malaria prevention and at the same time emerging
resistance against currently available antimalarials, the ongoing malaria
control programs have been severely hampered.
Besides
that, cross resistance among drugs due to their alike chemical combination is
also well evidenced . As a result of which, the current malaria control program
has been adversely affected by the development and spread of parasite resistant
strains to the working antimalarial, ACT (Artemisinin-based Combination
Therapy). Therefore, the need of the hour is to develop a drug not only that
has a quick and deep action in the parasite, but also by delaying the emergence
of drug resistance. Bearing these facts in mind, Baragana and co-workers5 have
recently designed a multiple stage antimalarial compound, which not only can
treat malaria with single dose but also help in chemo-protection and blockage
of transmission with less chance of development of resistance by the parasite.To
initiate the process of development of such a compound, the scientific team searched the chemical compound library at drug
discovery unit (DDU) of University of Dundee that consists of around 4700
compounds and screened against blood stage asexual forms of the deadliest
malaria parasite Plasmodium falciparum 3D7 strain. Read more...........
