We describe the synthesis and SAR of a series of analogues of the mGlu5 partial antagonist 5-(phenylethynyl)pyrimidine. New molecular switches are identified that modulate the pharmacological activity of the lead compound. Slight structural modifications around the proximal pyrimidine ring change activity of the partial antagonist lead to that of potent and selective full negative allosteric modulators
我们描述了 mGlu 5部分拮抗剂 5-(苯乙炔基) 嘧啶的一系列类似物的合成和 SAR 。确定了调节先导化合物药理活性的新分子开关。部分拮抗剂的近端嘧啶环变化活性周围的轻微结构修饰导致有效和选择性的完全负变构调节剂和正变构调节剂,它们分别在啮齿动物模型中证明了抗焦虑和抗精神病活性的体内功效。
