最近有报道称,对青蒿素衍生物(最后一类广泛有效的抗疟药)的耐受性增加,这支持了对新疗法的医学需求。螺四氢-β-咔啉或螺吲哚酮是一类新的速效和强效杀疟原虫药物,对恶性疟原虫和间日疟原虫临床分离株显示出低纳摩尔效力。螺吲哚酮迅速减少恶性疟原虫中的蛋白质合成,这种作用在编码P型阳离子转运蛋白ATP酶4(PfATP 4)的基因中携带非同义突变的寄生虫中被消除。优化的螺吲哚酮NITD 609显示出可接受的安全性特征和与每日一次口服给药相容的药代动力学性质;并在啮齿动物疟疾模型中证明了单剂量功效。总的来说,这些数据表明NITD 609具有适合于治疗疟疾的新候选药物的药理学特征。
Recent reports of increased tolerance to artemisinin derivatives—the last widely effective class of antimalarials — bolster the medical need for new treatments. The spirotetrahydro-β–carbolines, or spiroindolones, are a new class of fast-acting and potent schizonticidal drugs displaying low nanomolar potency against Plasmodium falciparum and Plasmodium vivax clinical isolates. Spiroindolones rapidly diminish protein synthesis in P. falciparum, an effect that is ablated in parasites bearing non-synonymous mutations in the gene encoding the P-type cation-transporter ATPase4 (PfATP4). The optimized spiroindolone NITD609 shows an acceptable safety profile and pharmacokinetic properties compatible with once-daily oral dosing; and demonstrates single-dose efficacy in a rodent malaria model. Collectively, these data demonstrate that NITD609 possesses a pharmacological profile suitable for a new drug candidate for the treatment of malaria.
