摘要: Background: Despite recent successes at controlling malaria, progress has stalled with an estimated 219 million cases and 435,000 deaths in 2017 alone. Combined emerging resistance to front line antimalarial therapies Southeast Asia, there is urgent need for new treatment options novel approaches halt the spread of malaria. Plasmodium, parasite responsible malaria propagates through mosquito transmission. This imposes acute bottleneck on population transmission-blocking interventions exploiting this vulnerability are recognized as vital elimination. Methods: 13,533 small molecules known activity against Plasmodium falciparum asexual parasites were screened additional ex vivo berghei ookinete development assay. Active then counterscreened dose response HepG2 cells determine their activity/cytotoxicity window selected non-toxic representative fully profiled a range transmission infection assays. Furthermore, entire dataset was compared other published screens same P. gametocytes female gametogenesis.
