compounds with cytotoxic effect demonstrated on different cancer types. In the present study, thirty-five 1,4-naphthoquinones tethered to 1,2,3-1H-triazoles were synthesized and the antitumor activity and molecular mechanisms were evaluated in several assays including in vitro and in vivo models of OSCC and normal oral human cells. Compounds 16a, 16b and 16 g were able to induce cytotoxicity in three different
尽管诊断和治疗取得了进步,但是口腔鳞状细胞癌(OSCC)由于其高发病率和低存活率而成为公共卫生问题。此外,最常见的OSCC化疗药物,如卡铂和顺铂,产生重要的副作用,证明开发新药的紧迫性。萘醌是一类重要的天然产物或合成化合物,对不同类型的癌症均显示出细胞毒作用。在本研究中,合成了35个与1,2,3-1 H-三唑拴在一起的1,4-萘醌,并在包括OSCC和正常人的体内和体外模型在内的多种测定中评估了其抗肿瘤活性和分子机制。口腔人类细胞。化合物16a,16b和16g能够在人OSCC的三种不同肿瘤细胞系(SCC4,SCC9和SCC25)中诱导细胞毒性,并且比经典和化学相似的对照对肿瘤细胞更具毒性和选择性(选择性指数,SI> 2) (卡铂和Lapachol)。化合物16g显示出较高的SI值。此外,化合物16A,16B和16克SCC9细胞显著减少集落形成在测试浓度。使用高浓度化合物16a,16b和16g
