The present invention is directed to compounds, intermediates and methods for making valerenic acid and its derivatives as well as the use of such compounds as GABAA receptor ligands.
gamma-aminobutyric acid (GABA) type A (GABA(A)) receptors can help to assess the physiological function of receptors with different subunit composition and also provide the basis for the development of new drugs. Valerenicacid (VA) was recently identified as a beta(2/3) subunit-specific modulator of GABA(A) receptors with anxiolytic potential. The aim of the present study was to generate VA derivatives as novel
背景和目的 γ-氨基丁酸 (GABA) A 型 (GABA(A)) 受体的亚基特异性调节剂可以帮助评估不同亚基组成的受体的生理功能,也为新药的开发提供基础。缬草酸 (VA) 最近被确定为具有抗焦虑潜力的 GABA(A) 受体的 beta(2/3) 亚基特异性调节剂。本研究的目的是生成 VA 衍生物作为新型 GABA(A) 受体调节剂,并深入了解该分子的构效关系。实验方法 VA 的羧基被不带电荷的酰胺或不同链长的酰胺取代。通过两微电极电压钳技术在非洲爪蟾卵母细胞中研究了由 VA 衍生物组成的不同亚基组成的 GABA(A) 受体的调节。通过 GABA(A) 受体 (EC(50)) 对 GABA 诱导的氯电流 (I(GABA)) 的半最大刺激和功效(I(GABA) 的最大刺激)进行了估计。应用高架十字迷宫试验在小鼠中研究了 VA 衍生物的抗焦虑活性。主要结果 缬草酸酰胺 (VA-A) 在 alpha(1)beta(

The streamlined synthesis implements a new one-pot reaction, which combines the addition of a Grignard species with an acid-catalyzed isomerization of the intermediate allylic alcohol. Further highlights are a stereo- and regioselective hydroxy-directed Diels–Alder reaction, a hydroxy-directed hydrogenation, and a final Negishi coupling reaction. After optimization of our synthesis, the preparation
