A novel class of H3 receptor antagonists, XB-1 analogues based on benzophenone or oxydibenzene scaffolds were synthesized, and their biological activities were evaluated to determine their in vitro neuroprotective effects against Aβ25–35-induced damage in primary cortical neurons and against glutamate-induced neuronal injury in primary cerebellar granule neurons. The results indicated that all of the tested analogues displayed neuroprotective activity at 0.1 μM or 1 μM. These findings may provide new insights into the development of novel promising H3 receptor antagonists with potential neuroprotective activity.
一类新型H3受体拮抗剂——基于苯并酮或氧二苯结构的XB-1类似物被合成,并评估了它们的生物活性,以确定它们对Aβ25–35诱导的原代皮层神经元损伤和谷氨酸诱导的原代小脑颗粒神经元损伤的体外神经保护作用。结果表明,所有测试的类似物在0.1 μM或1 μM浓度下均显示出神经保护活性。这些发现可能为开发具有潜在神经保护活性新型有前景的H3受体拮抗剂提供新思路。
