Article Synopsis
- - The lack of collaboration between academia and the pharmaceutical industry limits new drug discovery, but open source drug initiatives, like sharing physical compounds, could help bridge this gap and accelerate research.
- - The Medicines for Malaria Venture created the Malaria Box, a collection of over 400 compounds tested against malaria, which has been shared with almost 200 research groups, encouraging public data sharing on screening results.
- - Recent findings from the Malaria Box screenings revealed mechanisms of action for many compounds against various life stages of the malaria parasite, and some showed effectiveness against other pathogens and cancer cell lines, providing valuable data for further drug development.
Background: Schistosomiasis is responsible for a tremendous public health burden, yet only a single drug, praziquantel, is available. New antischistosomal treatments should therefore be developed. The accuracy, speed and objectivity of in vitro drug screening depend on the assay read-out.

A racemic mixture of R and S enantiomers of praziquantel (PZQ) is currently the treatment of choice for schistosomiasis. Though the S enantiomer and the metabolites are presumed to contribute only a little to the activity of the drug, in-depth side-by-side studies are lacking. The aim of this study was to investigate the in vitro activities of PZQ and its main metabolites, namely, R- and S-cis- and R- and S-trans-4'-hydroxypraziquantel, against adult worms and newly transformed schistosomula (NTS).

Methodology: We studied the antischistosomal properties of the Medicines for Malaria Venture (MMV) malaria box containing 200 diverse drug-like and 200 probe-like compounds with confirmed in vitro activity against Plasmodium falciparum.
