A series of 5-aryl-2-amino-imidazothiadiazole (ITD) derivatives were identified by a phenotype-based high-throughput screening using a blood stage Plasmodium falciparum (Pf) growth inhibition assay. A lead optimization program focused on improving antiplasmodium potency, selectivity against human kinases, and absorption, distribution, metabolism, excretion, and toxicity properties and extended pharmacological
使用血液分期恶性疟原虫( Pf ) 生长抑制试验,通过基于表型的高通量筛选鉴定了一系列 5-芳基-2-氨基-咪唑并噻二唑( ITD ) 衍生物。一项主要优化计划侧重于提高抗疟原虫效力、对人类激酶的选择性以及吸收、分布、代谢、排泄和毒性特性以及扩展的药理学特征,最终鉴定出INE963 ( 1 ),证明了对Pf 3D7的有效细胞活性。 EC 50 = 0.006 μM)并达到“青蒿素样”杀灭动力学在体外,寄生虫清除时间<24小时。单剂量 30 mg/kg 在Pf人源化严重联合免疫缺陷小鼠模型中完全治愈。INE963 ( 1 ) 在药物选择研究中还表现出很高的抗药性屏障和跨物种的长半衰期 ( T 1/2 )。这些特性表明INE963 ( 1 )具有巨大的潜力,可以通过短剂量方案为简单的疟疾提供治愈性疗法。由于这些原因,INE963 ( 1 ) 通过 GLP 毒理学研究取得了进展,目前正在进行 Ph1
