A novel series of trans-1,3-cyclohexyl diamides was discovered and characterized as mGluR5 negative allosteric modulators (NAMs) lacking an alkyne moiety. Conformational constraint of one of the amide bonds in the diamide template led to a spirooxazoline template. A representative compound (24d) showed good in vitro potency, high CNS penetration and, upon subcutaneous dosing, demonstrated efficacy
发现了一系列新的反式-1,3-环己基二酰胺,并将其表征为缺少炔烃部分的mGluR5负变构调节剂(NAM)。二酰胺模板中酰胺键之一的构象约束导致螺恶唑啉模板。代表性化合物(24d)表现出良好的体外效力,高的CNS渗透性,并且在皮下给药后,在小鼠大理石埋藏试验中显示出功效,通常用作潜在的抗焦虑活性的指标。
