substituted cinnamic α-asaronol esters and analogues were designed by Combination of Traditional Chinese Medicine Molecular Chemistry (CTCMMC) strategy, synthesized and tested systematically not only for anticonvulsant activity in three mouse models but also for LDH inhibitory activity. Thereinto, 68-70 and 75 displayed excellent and broad spectra of anticonvulsant activities with modest ability in preventing
受中药对远志治疗癫痫症的启发,结合中药分子化学(CTCMMC)策略设计了33种新型取代肉桂酸α-细辛醇酯及其类似物,不仅对抗惊厥药进行了系统合成和测试,在三种小鼠模型中具有活性,但对LDH的抑制活性也很高。其中,68-70和75表现出出色的抗惊厥活性谱,且具有适度的预防神经性疼痛的能力,并且神经毒性低。这四种化合物的保护指数均与替比妥醇,拉考酰胺,卡马西平和丙戊酸相比具有优势。68-70表现出良好的LDH1和LDH5抑制活性,且具有非竞争性抑制类型,并且比替替戊醇更有效。值得注意的是70 作为代表剂,也显示为对人α1β2γ2GABAA受体(EC50 46.3±7.3μM)的中等正变构调节剂。因此,有68-70种药物有望发展成为抗癫痫药,特别是用于治疗难治性癫痫病(例如Dravet综合征)。
