were synthesized and evaluated against tumour and normal cell lines. Among these, the compound named 3j initially showed relevant cytotoxicity and selectivity for tumour cells. Three analogues of 3j were designed and synthesized keeping in view the structural requirements of this compound. Almost all the tested compounds displayed considerable cytotoxicity. However, 8a, one of the 3j analogues, was shown
合成了新型嘧啶类硒脲并针对肿瘤和正常细胞系进行了评估。在这些化合物中,命名为3j的化合物最初对肿瘤细胞显示出相关的细胞毒性和选择性。考虑到该化合物的结构要求,设计并合成了3j的三个类似物。几乎所有测试的化合物都显示出相当大的细胞毒性。但是,3a类似物之一8a被证明具有高度选择性和细胞毒性,尤其是对于乳腺癌细胞(MCF-7)(IC 50 = 3.9μM)。此外,8a导致DNA损伤,抑制细胞增殖,能够在S期阻滞细胞周期并通过人乳腺癌细胞的凋亡诱导细胞死亡。此外,药代动力学特性的预测表明8a对于口服给药可能具有良好的吸收和渗透特性。总的来说,当前的研究确定了8a作为一种潜在的药物原型,可以用作治疗乳腺癌的DNA相互作用细胞毒剂。
