摘要: Naphthoquine (NQ), as a component of ARCO® which composed NQ and artemisinin, is new 4-aminoquinoline antimalarial synthesized by our institute. Here, naphthoquine-resistant line rodent malaria parasite was selected through exposing Plasmodium berghei Keyberg 173 strain to progressively increased drug pressure. The showed more than 200-fold decreased susceptibility with stable resistance phenotype after 10 serial passages without pressure or when cryopreserved over period 12 months. In cross-resistance assay, the NQ-resistant parasites chloroquine 14.5-fold. These findings imply might be long-term usage in epidemic areas efficacy chloroquine-resistant falciparum should monitored closely.
