The emergence and spread of drug resistance in Plasmodium falciparum, the parasite causing the most severe form of human malaria, is a major threat to malaria control and elimination programs around the globe. With P. falciparum having evolved widespread resistance against a number of previously widely used drugs, currently, artemisinin (ART) and its derivatives are the cornerstones of first-line treatments of uncomplicated malaria. However, growing incidences of ART failure reflect the spread of ART-resistant P. falciparum strains. Despite current efforts to understand the primary cause of ART resistance due to mutations in the Kelch 13 gene (PfK13), the mechanism underlying ART resistance is still not completely unclear and no feasible strategies to counteract the causes and thereby restoring the efficiency of ART have been developed. We use a polypharmacology approach to identify potential drugs that can be used for the novel purpose (target). Of note, we have designed a multimodal stratagem to identify approved drugs with a potential antimalarial activity using computational drug reprofiling. Our investigations suggest that oxetacaine, simvastatin, repaglinide, aclidinium, propafenone, and lovastatin could be repurposed for malaria control and prevention.
疟原虫(Plasmodium falciparum)的出现和耐药性的传播对全球疟疾控制和消除计划构成了重大威胁,疟原虫是导致人类疟疾最严重形式的寄生虫。由于疟原虫对许多以前广泛使用的药物产生了广泛的耐药性,目前青蒿素(ART)及其衍生物是治疗无并发症疟疾的一线药物的基石。然而,青蒿素耐药疟原虫株的传播导致青蒿素耐药性病例不断增加。尽管目前正在努力了解由于 Kelch 13 基因(PfK13)突变导致的 ART 耐药的主要原因,但 ART 耐药的机制仍不完全清楚,也没有针对这些原因并恢复 ART 效率的可行策略。我们使用多药理学方法来确定可用于新型用途(靶标)的潜在药物。值得注意的是,我们设计了一种多模式策略,利用计算药物再定位来识别具有潜在抗疟活性的已批准药物。我们的研究表明,氧烷卡因、辛伐他汀、瑞格列奈、阿地氯铵、普罗帕酮和洛伐他汀可被重新用于疟疾的控制和预防。
