New antibacterials for the treatment of toxoplasmosis; a patent review

A new and safe chemotherapy is needed, as T. gondii causes serious morbidity and mortality in pregnant women and immunodeficient patients undergoing chemotherapy. A particular drawback of the available treatments is the lack of efficacy against the tissue cyst of the parasite. During this review a broad scope of several attractive targets for drug design have been presented. In this context, the isoprenoid pathway, dihydrofolate reductase, T. gondii histone deacetylase are promising molecular targets.
