Likewise, radical scavenging properties of the new selenadiazole derivatives were confirmed by testing their ability to scavenge DPPH radicals. Four compounds (1, 2, 8 and 9) showed potent radical scavenging activity, compound 9 being the most effective. Overall, while compound 7 was identified as the most cell growth inhibitory agent and selectively toxic to cancer cells, compound 9 proved to be the
设计并合成了27种新颖的苯并[ c ] [1,2,5]硒二唑-5-羧酸(BSCA)衍生物。这些结构的抗增殖活性在体外针对一组五种人类癌细胞系进行了测试,其中包括前列腺癌(PC-3),结肠癌(HT-29),白血病(CCRF-CEM),肺癌(HTB-54)和乳房(MCF-7)。四种化合物(5,6,7和19)显示出有效的抑制活性与GI 50点小于10μm的值在癌细胞系中的至少一个。在源自乳房(184B5)和肺(BEAS-2B)的两种非恶性细胞系中进一步检查了这些化合物的选择性。化合物7 在MCF-7细胞中显示出有希望的抗增殖活性(GI 50 = 3.7μM),同时具有高选择性指数(SI> 27.1)。 化合物7对细胞死亡的诱导与凋亡过程无关,并且它也不影响细胞周期进程。同样,通过测试新硒代二唑衍生物清除DPPH自由基的能力也证实了其清除自由基的性能。四种化合物(1,2,8和9)显示了强的自由基清
