Shared Consensus Machine Learning Models for Predicting Blood Stage Malaria Inhibition

The development of new antimalarial therapies is essential, and lowering the barrier of entry for the screening and discovery of new lead compound classes can spur drug development at organizations that may not have large compound screening libraries or resources to conduct high-throughput screens. Machine learning models have been long established to be more robust and have a larger domain of applicability with larger training sets. Screens over multiple data sets to find compounds with potential malaria blood stage inhibitory activity have been used to generate multiple Bayesian models. Here we describe a method by which Bayesian quantitative structure–activity relationship models, which contain information on thousands to millions of proprietary compounds, can be shared between collaborators at both for-profit and not-for-profit institutions. This model-sharing paradigm allows for the development of consensus models that have increased predictive power over any single model and yet does not reveal the identity of any compounds in the training sets.

Genetic diversity of next generation antimalarial targets: A baseline for drug resistance surveillance programmes

CiteULike malaria tags - 5 April 2017 - 9:41am
International Journal for Parasitology: Drugs and Drug Resistance, Vol. 7, No. 2. (August 2017), pp. 174-180, doi:10.1016/j.ijpddr.2017.03.001

Genetic diversity of 11gene-targets of new antimalarial compounds was investigated. Genetic data was analysed for 18 malaria endemic countries. No signals of selective pressure was observed. A mutation linked to resistance to a new antimalarial was found in African parasites. Amino-acid changes close to reported antimalarial resistant mutations were detected. Drug resistance is a recurrent problem in the fight against malaria. Genetic and epidemiological surveillance of antimalarial resistant parasite alleles is crucial to guide drug therapies and clinical management. New antimalarial compounds are currently at various stages of clinical trials and regulatory evaluation. Using ∼2000 Plasmodium falciparum genome sequences, we investigated the genetic diversity of eleven gene-targets of promising antimalarial compounds and assessed their potential efficiency across malaria endemic regions. We determined if the loci are under selection prior to the introduction of new drugs and established a baseline of genetic variance, including potential resistant alleles, for future surveillance programmes.
