DS-1971a. In preclinical studies, DS-1971a demonstrated highly potentselective in vitro profile with robust efficacy in vivo. DS-1971a exhibited a favorable toxicological profile, which enabled multiple-dose studies of up to 600 mg bid or 400 mg tid (1200 mg/day) administered for 14 days to healthy human males. DS-1971a is expected to exert potent efficacy in patients with peripheral neuropathic pain, with
已经发现了一种高效的,选择性的Na V 1.7抑制剂DS-1971a。对磺酰胺衍生物(I和II)的左苯环的探索导致发现了一系列新的具有高Na V的环烷烃衍生物1.7体外抑制能力。由于右手杂芳环影响CYP3A4的基于机理的抑制作用,该部分的取代导致4-嘧啶基衍生物的产生。另外,通过该修饰成功地避免了可引起特异药物毒性的GSH加合物的形成。附加的优化导致发现DS-1971a。在临床前研究中,DS-1971a表现出高效的选择性体外概况,在体内具有强大的功效。DS-1971a表现出良好的毒理学特征,能够对健康的男性雄性进行长达14天的多剂量研究,最高剂量为600 mg bid或400 mg tid(1200 mg /天)。DS-1971a有望在周围神经性疼痛患者中发挥强效疗效,并具有良好的安全性。
