cancer cells with different epidermal growth factor receptor (EGFR) status. Pyridyl substituents could be used to replace the C2 and N9 phenyl moieties in the purine-type scaffold, which can help to improve the solubility under physiological conditions, thus increasing cytotoxicity. In mice treated with the purine–hydroxamate conjugates, the tumor growth rate was significantly reduced without causing toxic
双靶向抗癌药物4-29是结合嘌呤型微管破坏化合物和HDAC抑制剂的结构特征而设计的。合成了通过适当接头连接的缀合物化合物库,并发现其具有 HDAC 抑制活性,并通过激活剑蛋白(一种微管切断蛋白)来产生微管断裂。在各种锌结合基团中,异羟肟酸对 I 类 HDAC 具有最高的抑制活性,这也通过三维定量构效关系(3D-QSAR)药效团预测再次得到证实。嘌呤-异羟肟酸缀合物对 MDA-MB231 乳腺癌细胞、H1975 肺癌细胞和具有不同表皮生长因子受体 (EGFR) 状态的各种临床分离的非小细胞肺癌细胞表现出增强的细胞毒性。吡啶基取代基可用于取代嘌呤型支架中的C2和N9苯基部分,有助于提高生理条件下的溶解度,从而增加细胞毒性。在用嘌呤-异羟肟酸结合物治疗的小鼠中,肿瘤生长速度显着降低,且没有引起毒性作用。我们的研究证明了双靶向嘌呤-异羟肟酸化合物用于癌症单一疗法的潜力。
