Transmission blocking inhibitors of Malaria

疟原虫疟疾仍然是一个巨大的公共卫生负担。为了维持最近在降低疟疾相关发病率和死亡率方面取得的进展，需要在开发有可能阻断疾病传播的抗疟药物方面取得进一步进展。为了确定先导开发候选者以及寄生虫传播到蚊子载体所必需的新生物途径，NCGC科学家将新型受精试验优化并小型化为1536孔格式，提供了对早期蚊子阶段进行高通量化合物评估的机会。初步研究已经筛选了MIPE化合物库，其中有2，480种小分子具有注释的作用机制，鉴定了135种化合物，其抑制受精的IC 50低于2 μ M。目前正在进行验证这些命中以及筛选批准的药物集合重新利用的工作。

Plasmodium malaria remains a tremendous public health burden. In order to sustain recent progress in decreasing malaria related morbidity and mortality further progress in development of antimalarials with potential to interrupt disease transmission are required. To identify lead development candidates as well as novel biological pathways essential for parasite transmission to the mosquito vector NCGC scientists have optimized and miniaturized the novel fertilization assay to 1536-well format, providing the opportunity to conduct high-throughput evaluation of compounds against early mosquito stages. Initial studies have already screened the Mechanism of Interrogation PlatE (MIPE) compound library, with 2,480 small molecules with annotated mechanisms of action, identifying 135 compounds that inhibited fertilization with IC50s under 2 uM. Work is proceeding with validating these hits as well as screening approved drug collections for repurposing efforts.
