reactive oxygen species and inhibit cell invasion and migration in HCT-116 cells. Further studies revealed that 10c could up-regulate the acetylation levels of H3 and α-tubulin, exhibit significant Topo I inhibition and induce the release of related apoptotic biomarkers. These results highlight the great potential of 10c to become a promising anti-cancer HDACinhibitor.

yielding IC50 values of 6–60 μM for three unsubstituted metal-free ligands, whereas values for the metal complexes vary in a broad range from 0.3 to 140 μM. Complexation with osmium of quinoxalinone derivatives with benzimidazole or benzothiazole results in a more consistent increase in cytotoxicity than complexation with ruthenium. For selected compounds, the capacity to induce apoptosis was confirmed
已合成了一系列具有 3-(1 H-苯并咪唑-2-基)-1 H-喹喔啉-2-one 的钌 (II) 芳烃配合物,具有已知蛋白激酶抑制剂的药效基团,以及相关的苯并恶唑和苯并噻唑衍生物. 此外,还制备了相应的未取代配体的锇配合物。这些化合物已通过 NMR、UV-vis 和 IR 光谱、ESI 质谱、元素分析和 X 射线晶体学进行了表征。通过 MTT 测定法测定三种人类癌细胞系(A549、CH1、SW480)的抗增殖活性,产生 IC 50三个未取代的无金属配体的值为 6-60 μM,而金属配合物的值在 0.3 至 140 μM 的宽范围内变化。与苯并咪唑或苯并噻唑与喹喔啉酮衍生物的锇络合导致比与钌络合更一致地增加细胞毒性。对于选定的化合物,通过荧光显微镜和流式细胞术分析证实了诱导细胞凋亡的能力,而细胞周期效应只是中等的。
Identification of 3-(benzazol-2-yl)quinoxaline derivatives as potent anticancer compounds: Privileged structure-based design, synthesis, and bioactive evaluation in vitro and in vivo
structural characteristics of numerous known antitumor compounds targeting DNA or topoisomerase I, 3-(benzazol-2-yl)-quinoxaline-based scaffold was designed via the combination of two important privileged structure units —quinoxaline and benzazole. Thirty novel 3-(benzazol-2-yl)-quinoxaline derivatives were synthesized and evaluated for their biological activities. The MTT assay indicated that most
