The increasing resistance of malarial parasites to almost all available drugs calls for the identification of new compounds and the detection of novel targets. Here, we establish the antimalarial activities of risedronate, one of the most potent bisphosphonates clinically used to treat bone resorption diseases, against blood stages of Plasmodium falciparum(More)
Nerolidol is a naturally occurring sesquiterpene found in the essential oils of many types of flowers and plants. It is frequently used in cosmetics, as a food flavoring agent, and in cleaning products. In addition, nerolidol is used as a skin penetration enhancer for transdermal delivery of therapeutic drugs. However, nerolidol is hemolytic at low(More)
Infection with a sexually transmitted disease (STD) increases the risk for human immunodeficiency virus (HIV) infection. Polymorphonuclear leukocytes (PMNs) are recruited into the genital tract by STD pathogens, such as Chlamydia trachomatis. Semen of HIV-infected men contains HIV associated with mononuclear cells. This study investigated the interaction(More)
Previous studies have shown that fosmidomycin, risedronate, and nerolidol exert antimalarial activity in vitro. We included squalestatin, an inhibitor of the isoprenoid metabolism in Erwinia uredovora, and found that combinations of compounds which act on different targets of the plasmodial isoprenoid pathway possess important supra-additivity effects.
Malaria, an infectious disease that kills more than 438,000 people per year worldwide, is a major public health problem. The emergence of strains resistant to conventional therapeutic agents necessitates the discovery of new drugs. We previously demonstrated that various substances, including terpenes, have antimalarial activity in vitro and in vivo.(More)
