against DLA cells by in vitro and in vivo studies. The results suggested that, compounds 8b with fluoro group and 8e with chloro substituent at the benzoyl ring of benzophenone scaffold as well as pyridine ring with hydroxy group exhibited significant activity. Further investigation in mouse model suggests that compounds 8b and 8e have the potency to activate caspase activated DNase (endonuclease) which
通过多步反应序列合成了一系列具有
吡啶核8a - 1的
二苯甲酮,并通过体外和体内研究评估了其对D
LA细胞的抗增殖活性。结果表明,在
二苯甲酮骨架的
苯甲酰基环上具有
氟基的化合物8b和具有
氯取代基的化合物8e以及具有羟基的
吡啶环均显示出显着的活性。小鼠模型的进一步研究表明化合物8b和8e 具有激活caspase活化的DNase(
核酸内切酶)的能力,该酶负责DNA片段化,这是细胞凋亡的主要标志,从而抑制了道尔顿淋巴瘤腹
水肿瘤的生长。
