Twenty-six novel 1,2,4-triazolo [3,4-b][1,3,4] thiadiazines containing furan and thiophene nucleus were designed, synthesized and evaluated for their antiproliferative activities. The results indicated that most of the compounds showed moderate to potent antiproliferative activities against four cancer cell lines, PC-3, HepG2, A549, and MCF-7. Particularly, compound 32 showed eleven-, three-, and two-fold
设计,合成并评价了26种新颖的含呋喃和噻吩核的1,2,4-三唑并[3,4-b] [1,3,4]噻二嗪的抗增殖活性。结果表明,大多数化合物对四种癌细胞系PC-3,HepG2,A549和MCF-7具有中等至强效的抗增殖活性。特别是,与阳性对照氟尿嘧啶相比,化合物32在抑制HepG2,PC-3和A549细胞增殖方面显示出十一倍,三倍和两倍的改善,IC 50值分别为5.09、3.70和12.74μM。进一步的流激活细胞分选分析表明,最有前途的化合物32在PC-3细胞中对G2 / M细胞周期停滞具有显着的剂量依赖性。
