cure chemotherapy-induced neuropathy. In the present study, we describe the structural design, synthesis, chemical and pharmacological characterization of 15 thiazolidinones, a class of potential analgesic compounds. The synthesis of new thiazolidinones was achieved by using the thiazolidinone heterocyclic as main structural pharmacophoric group and varying the substituents attached to the phenyl near
化学疗法诱发的神经病是癌症化疗导致的致残性疼痛症状。到目前为止,尚无可用于治疗化学疗法诱发的神经病的药物。在本研究中,我们描述了15种噻唑烷酮(一种潜在的止痛化合物)的结构设计,合成,化学和药理学表征。通过使用噻唑烷酮杂环作为主要结构药效基团并改变连接至亚氨基键附近的苯基的取代基,可以合成新的噻唑烷酮。使用von Frey,rota-rod和开放视野试验,在奥沙利铂诱导的神经性疼痛的小鼠模型中研究了该化合物的镇痛潜力。除化合物14外,这些噻唑烷酮类具有镇痛特性,而不会引起运动障碍。噻唑烷酮12 图15和图16显示了剂量依赖性的抗伤害感受作用,与加巴喷丁(一种用于神经性疼痛的金标准药物)相比,具有相似的功效和增强的功效。此外,16的抗伤害感受活性比加巴喷丁持续时间更长。噻唑烷酮的抗伤害感受作用被PPARγ拮抗剂GW9662阻止。主要的抗伤害感受性化合物表现出Lipinski指数阳性,预示其口
