monotherapy. We developed a series of caffeine derivatives and evaluated their antiproliferative effects on 11 human tumour cell lines and compared them against caffeine and a standard ATR inhibitor VE-821. Although the new caffeine derivatives did not achieve the overall potency of VE-821, several compounds exhibited enhanced antiproliferative activity compared to caffeine and in some cell lines showed at
咖啡因可能是世界上最知名,使用最广泛的精神活性物质。除了抑制精神活性外,还发现
咖啡因会抑制ATM和ATR激酶,从而影响细胞周期和DNA修复。这两个DNA损伤反应激酶是
磷脂酰肌醇3-激酶相关蛋白激酶家族的成员,代表了非常有吸引力的抗癌药物靶标。它们的抑制作用可以选择性地使癌细胞对DNA破坏剂敏感,甚至可以在单一疗法中杀死各种肿瘤细胞。我们开发了一系列
