Twelve novel hybrids of slowly releasing hydrogen sulfide donor ADT-OH combined with nicotinic acid were synthesized. All of their structures had been confirmed by 1H NMR, 13C NMR and MS spectra. The target compounds were evaluated for their neuroprotective effects on hippocampal neuron HT22 cells against glutamate-induced injury at the concentrations of 1–100 μM with MTT assay, and their toxicity
合成了十二种新的缓释硫化氢供体ADT-OH与烟酸结合的杂种。所有结构均通过1 H NMR确证,131 H NMR和MS光谱。用MTT分析评估目标化合物对谷氨酸诱导的损伤对海马神经元HT22细胞的神经保护作用,并在100μM浓度对未经谷氨酰胺处理的HT22细胞的毒性。在永久性大脑中动脉闭塞(pMCAO)小鼠模型中,在缺血后3小时通过腹膜内注射进一步研究了该活性化合物对缺血性梗死体积的影响。结果表明,所有化合物在大多数实验浓度下均能显着保护HT22细胞免受谷氨酸诱导的损伤,并且在高浓度下对正常HT22细胞没有或只有很少的神经毒性。更重要的是,化合物A6在pMCAO模型中显着减少了梗塞体积。这些结果表明,化合物A6可能有望用于进一步评估对脑缺血损伤的干预。
