5-dihydro-1H-imidazole) (carbophenyline). The purpose of this work was the preclinical evaluation of the efficacy of carbophenyline on oxaliplatin-induced neuropathic pain in mice. Carbophenyline, acutely per os administered (0.1–10 mg kg−1), induced a dose-dependent anti-hyperalgesic effect that was completely blocked by the pre-treatment with the I1-R antagonist 3 or the I1/α2 receptor antagonist efaroxan
基于重复施用奥沙利铂的抗癌治疗受到对患者生活质量产生不利影响的致残性神经性综合征的发展的限制。缺乏有效的药理学方法需要确定基于新靶点的创新治疗策略。我们将注意力集中在咪唑啉 I 1受体 (I 1 -R) 上,特别是选择性 I 1 -R 激动剂 2-(1-([1,1'-联苯]-2-基)丙-2-基)-4,5-二氢-1H-咪唑)(碳苯啉)。这项工作的目的是临床前评估卡巴苯林对奥沙利铂引起的小鼠神经性疼痛的疗效。经口急性给药(0.1–10 mg kg -1 )卡苯苯啉可诱导剂量依赖性抗痛觉过敏作用,该作用可被 I 1 -R 拮抗剂3或 I 1 /α 2受体预处理完全阻断拮抗剂 efaroxan,证实了 I 1 -R 依赖性机制。相反,用I 2 -R拮抗剂BU224预处理并不能阻断由卡巴苯林引起的抗伤害感受作用。从注射奥沙利铂的第一天开始,重复口服碳苯啉(1 mg kg -1 )14天,在所有行为测试(冷板、Von
