Novel Synthetic Polyamines Have Potent Antimalarial Activities in vitro and in vivo by Decreasing Intracellular Spermidine and Spermine Concentrations
Frontiers in Cellular and Infection Microbiology
Twenty-two compounds belonging to several classes of polyamine analogs have been examined for their ability to inhibit the growth of the human malaria parasite Plasmodium falciparum in vitro and in vivo. Four lead compounds from the thiourea sub-series and one compound from the urea-based analogs were found to be potent inhibitors of both chloroquine-resistant (Dd2) and chloroquine-sensitive (3D7) strains of Plasmodium with IC 50 values ranging from 150 to 460 nM. In addition, the compound RHW,doi:10.3389/fcimb.2019.00009 fatcat:ezl67b4kxnek5lqjq7iwskjhhe
