The World Health Organization has estimated that over 200 million people suffered from malaria in 2010 and that over 600,000 people died from it that year. Growing problems with resistance to existing anti-malarial drugs makes identification of new drugs a high priority. We applied a series of state-of-the-art In Silico tools to publicly available activity data from screens carried out on intact Plasmodium falciparum parasites to yield a handful of candidate molecules predicted to combine potency with good absorption, distribution, metabolism, excretion and toxicity (ADMET) properties. Here we describe the overall process used to design these molecules and report encouraging results for their activity against the parasite in culture. We also show that the ADMET properties predicted for them generally compare well to the experimentally determined values.
Bioluminescent Assay for GTPases Allows Measurement of GTPase, GAP and GEF ActivitiesPoster
