Design, synthesis, molecular modeling, DFT, ADME and biological evaluation studies of some new 1,3,4-oxadiazole linked benzimidazoles as anticancer agents and aromatase inhibitors
hormone-dependent tumors, which is very likely be treated with hormonal therapy. Aromatase is involved in the biosynthesis of estrogen thus a critical target for breast cancer. In this study, in order to identify new aromatase enzyme inhibitors, a series of benzimidazole-1,3,4-oxadiazole derivatives were synthesized and characterized by 1H NMR, 13C NMR, and MS spectra analyses. In the in vitroanticancer assay
摘要 乳腺癌是最常见的女性癌症,也是全世界女性癌症相关死亡的第二大原因。三分之二的乳腺癌患者患有激素依赖性肿瘤,很可能需要激素治疗。芳香化酶参与雌激素的生物合成,因此是乳腺癌的关键靶点。在这项研究中,为了鉴定新的芳香酶抑制剂,合成了一系列苯并咪唑-1,3,4-恶二唑衍生物,并通过1 H NMR、13 C NMR 和 MS 光谱分析对其进行了表征。在体外抗癌试验中,使用基于 MTT 的试验对五种癌细胞系(MCF-7、A549、HeLa、C6 和 HepG2)测试了所有化合物的抗癌活性。其中,化合物5a表现出最强的活性,针对 MCF-7 和 HepG2 细胞系的IC 50值为 5.165 ± 0.211 μM 和 5.995 ± 0.264 μM。化合物5a包含在 BrdU 测试中,以确定对两种细胞类型的 DNA 合成抑制作用。此外,化合物5c还被发现比多柔比星对 HeLa 细胞系更有效。在 NIH3T3

significant growthinhibition in diverse cancer cell lines. Compound stood out with a GI range of 1.23 – 3.38 µM on melanomacell lines. Encouraged by its efficacy, it was further investigated for its antitumor activity and mechanism of action, using sorafenib as a reference standard. The hybrid compound exhibited potent cellular-level suppression of BRAF, VEGFR-2, and FGFR-1 in A375 cell line, surpassing
