描述 | Mefloquine (Hydrochloride) is a quinoline antimalarial drug that is structurally related to the antiarrhythmic agent quinidine. Mefloquine is widely used in both the treatment and prophylaxis of Plasmodium falciparum malaria. Mefloquine can prolong cardiac repolarization, especially when coadministered with halofantrine, an antagonist of the human ether-a-go-go-related gene (HERG) cardiac K+ channel. Using patch-clamp electrophysiology we found that mefloquine inhibited KvLQT1/minK channel currents with an IC50 value of approximately 1 microM[2]. Mefloquine possesses activity against the Mycobacterium tuberculosis (Mtb) as well as against multidrugresistant tuberculosis (MDR) and other types of bacteria[3]. The anti-malarial mefloquine was previously shown to be active against E. multilocularis metacestodes in vitro, and in mice infected by intraperitoneal inoculation of metacestodes when administered at 100 mg/kg by oral gavage twice a week for 12 weeks. After 12 weeks of treatment, the presence of parasite lesions was assessed in a liver squeeze chamber and by PCR, and a significantly reduced parasite load was found in mefloquine-treated animals[4]. Mefloquine (MQ) has a highly selective cytotoxicity that inhibits PCa (prostate cancer) cell growth. MQ also induces hyperpolarization of the mitochondrial membrane potential (MMP), as well as ROS (reactive oxygen species) generation[1]. |
