The active conformation of a family of metabotropic glutamate receptor subtype 4 (mGlu4) positive allosteric modulators (PAMs) with the cyclohexane 1,2‐dicarboxylic scaffold present in cis‐2‐(3,5‐dichlorophenylcarbamoyl)cyclohexanecarboxylic acid (VU0155041) was investigated by testing structurally similar six‐membered ring compounds that have a locked conformation. The norbornane and cyclohexane molecules
一个代谢型谷氨酸受体亚型4(mGlu 4)阳性变构调节剂(PAM)家族的活性构型与顺式-2-(3,5-二氯苯基氨基甲酰基)环己烷羧酸(VU0155041)中存在的环己烷1,2-二羧酸骨架相符通过测试结构相似的具有锁定构象的六元环化合物进行了研究。设计成组mGlu降冰片烷和环己烷分子4个构象探针和对映异构体的反式非对映体进行了计算,其特征在于和组mGlu测试4药理分析。结果支持VU0155041活性构象,其中椅子环己烷在轴向位置具有芳族酰胺取代基并且在赤道位置具有羧酸盐。此外,该受体显示出手性PAM的对映体鉴别。所构建的药效团具有高度受限的mGlu 4变构结合位点,因此为mGlu 4 PAM的基于结构的药物设计迈出了一步。
