(ADNFLE). Effective treatment options for KCNT1-related disease are absent, and novel therapies are urgently required. We describe the development of a novel class of oxadiazole KNa1.1 inhibitors, leading to the discovery of compound 31 that reduced seizures and interictal spikes in a mouse model of KCNT1 GoF.
基因KCNT1编码钠激活钾通道 K Na 1.1(Slack、Slo2.2)。 KCNT1基因的变异会诱导离子电流的功能获得(GoF)表型,并导致婴儿和儿童出现一系列顽固性神经系统疾病,包括伴有迁移性局灶性癫痫发作的婴儿期癫痫(EIMFS)和常染色体显性遗传性夜间额叶癫痫(ADNFLE)。 KCNT1相关疾病缺乏有效的治疗方案,迫切需要新的疗法。我们描述了新型恶二唑 K Na 1.1 抑制剂的开发,从而发现了化合物31 ,该化合物可减少KCNT1 GoF 小鼠模型的癫痫发作和发作间期尖峰。
