A series of potent quinazolinedione sulfonamide antagonists of the α‐amino‐3‐hydroxy‐5‐methyl‐4‐isoxazole‐propionic acid (AMPA) receptor were designed and synthesized. The structure–activity relationships (SAR) and in vivo activity of the series were investigated. In particular, compound 1 S (selurampanel; N‐[7‐isopropyl‐6‐(2‐methylpyrazol‐3‐yl)‐2,4‐dioxo‐1H‐quinazolin‐3‐yl]methanesulfonamide) has
设计并合成了一系列有效的α-氨基-3-羟基-5-甲基-4-异恶唑丙酸(AMPA)受体的喹唑啉二酮磺酰胺拮抗剂。研究了该系列的结构活性关系(SAR)和体内活性。尤其是化合物1 S(三氢呋喃; N- [7-异丙基-6-(2-甲基吡唑-3-基)-2-,4-二氧-1H-喹唑啉-3-基]甲烷磺酰胺)具有出色的口服药效可以最大程度地防止啮齿动物遭受最大电击惊厥(MES)引起的全身性强直-阵挛性癫痫发作,以及各种形式的癫痫患者的显着活动。还获得了与AMPA受体hGluA结合的selurampanel的X射线晶体结构。
