novel, potent, and selective triazafluorenone series of metabotropic glutamate receptor 1 (mGluR1) antagonists with efficacy in various rat pain models. Pharmacokinetic and pharmacodynamic profiles of these triazafluorenone analogs revealed that brain/plasma ratios of these mGluR1 antagonists were important to achieve efficacy in neuropathic pain models. This correlation could be used to guide our in
我们发现了一种新型,有效和选择性的三氮杂芴酮系列代谢型谷氨酸受体1(mGluR1)拮抗剂,在各种大鼠疼痛模型中均具有功效。这些三氮杂芴酮类似物的药代动力学和药效学特征表明,这些mGluR1拮抗剂的脑/血浆比例对于在神经性疼痛模型中实现疗效很重要。这种相关性可以用来指导我们体内的SAR(结构-活性关系)修饰。例如,化合物4a的脑/血浆比例为0.34,仅在神经性疼痛模型中显示出中等功效。另一方面,脑/血浆比例为2.70的拮抗剂4b在神经性疼痛模型中完全有效。
