μ-Conotoxin KIIIA blocks voltage-gated sodium channels and displays potent analgesic activity in mice models for pain. Structure–activity studies with KIIIA have shown that residues important for sodium channel activity are presented on an α-helix. Herein, we report the de novo design and synthesis of a three-residue (Lys7, Trp8, His12) peptidomimetic based on a novel diketopiperazine (DKP) carboxamide
μ-ConotoxinKIIIA可以阻断电压门控的钠通道,并在小鼠疼痛模型中显示出有效的镇痛作用。用KIIIA进行的结构活性研究表明,对钠通道活性重要的残基出现在α-螺旋上。在此,我们报告了基于新型二酮哌嗪(DKP)羧酰胺支架的三残基(Lys7,Trp8,His12)拟肽的从头设计和合成。
