feature of several neurodegenerative disorders, including Alzheimer's disease, 2 and novel analogues (3-16) were synthesized to (i) assess the value of tetrahydrobenzothiazole analogues as neuroprotective agents and (ii) define the structural requirements for p53 inactivation. Not only did 2 exhibit neuroprotective activity in both tissue culture and in vivo stroke models but also compounds 6, 7, 10, 13
肿瘤抑制蛋白p53是一种细胞内蛋白,在生化级联反应中至关重要,可通过凋亡导致细胞死亡。最近的研究确定了四氢苯并噻唑类似物pifithrin-alpha(2)作为p53抑制剂,可有效保护神经元细胞免受各种致命伤害并减少抗癌药物的副作用。由于p53的上调已被描述为包括阿尔茨海默氏病在内的几种神经退行性疾病的共同特征,因此合成了2种和新型类似物(3-16)以(i)评估四氢苯并噻唑类似物作为神经保护剂的价值,以及(ii)定义p53失活的结构要求。不仅2在组织培养和体内中风模型中均表现出神经保护活性,而且化合物6、7、10、13、15
