Mefloquine hydrochloride is a quinoline antimalarial drug that is structurally related to the antiarrhythmic agent quinidine. IC50 Value: 1 microM ( for K+ channel) [1]Target: AntiparasiticMefloquine is widely used in both the treatment and prophylaxis of Plasmodium falciparum malaria. MQ can induces oxidative stress in vitro. Evidence indicates that reactive oxygen species (ROS) may be used as a therapeutic modality to kill cancer cells [2].in vitro: Mefloquine inhibitedKvLQT1/minK channel currents with an IC50 value of approximately 1 microM. Mefloquine slowed the activation rate of KvLQT1/minK and more block was evident at lower membrane potentials compared with higher ones. HERG channel currents were about 6-fold less sensitive to block by mefloquine (IC50 = 5.6 microM). Block of HERG displayed a positive voltage dependence with maximal inhibition obtained at more depolarized potentials [1]. MQ has a highly selective cytotoxicity that inhibits PCa cell growth. MQ-mediated ROS simultaneously downregulated Akt phosphorylation and activated extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK) and adenosine monophosphate-activated protein kinase (AMPK) signaling in PC3 cells [2]. in vivo: Pregnant rats were treated orally with AS (15 and 40 mg/kg body weight (bwt)/day), MQ (30 and 80 mg/kg bwt/day) and AS/MQ (15/30 and 40/80 mg/kg bwt/day) on days 9-11 post coitum (pc).
