The primary goal of this study is to synthesize and characterize N-substituted Acetamido derivatives of acridone, where the acetamido moiety has been considered a linker which is crucial for several biological activities, including anti-cancer activity. In this context, the anti-proliferative activity of synthesized derivatives was evaluated against human breast (MCF-7, MDA-MB-231), lung (A-549), and skin (A-431) cancer cell lines. Results revealed that compounds 8 h, 8i, 9 h, and 9i showed the most potent activity against MCF-7 cell lines with IC50 values of 13.96 µM, 8.25 µM, 9.45 µM, and 6.76 µM, respectively. In addition, all these compounds were found to be non-toxic against normal cells (NIH/3T3). Further, AKT kinase inhibition assay results showed that compounds 8i and 9i have the efficacy to inhibit the AKT kinase with potential anti-cancer activity. The cell cycle analysis revealed that compounds 8i and 9i could arrest the G0/G1 phase of the cell cycle and absorption titration with CT-DNA identified that these molecules could interact with DNA. In order to understand the drug-likeness properties, all the compounds were evaluated by various in silico screening, and these compounds exhibited optimal physicochemical features as excellent lead molecules. Finally, in vitro results were validated using a molecular docking study, which revealed binding interactions in the active site of AKT.
本研究的主要目标是合成和表征吖啶酮的 N-取代乙酰氨基衍生物,其中乙酰氨基被认为是一种连接体,对多种生物活性(包括抗癌活性)至关重要。为此,研究人员评估了合成衍生物对人类乳腺癌(MCF-7、MDA-MB-231)、肺癌(A-549)和皮肤癌(A-431)细胞系的抗增殖活性。结果表明,化合物 8 h、8i、9 h 和 9i 对 MCF-7 细胞株表现出最强的活性,IC50 值分别为 13.96 µM、8.25 µM、9.45 µM 和 6.76 µM。此外,所有这些化合物对正常细胞(NIH/3T3)均无毒性。此外,AKT 激酶抑制实验结果表明,化合物 8i 和 9i 具有抑制 AKT 激酶的功效,具有潜在的抗癌活性。细胞周期分析表明,化合物 8i 和 9i 可阻滞细胞周期的 G0/G1 期,而与 CT-DNA 的吸收滴定则表明这些分子可与 DNA 发生相互作用。为了了解这些化合物的药物相似性,对所有化合物进行了不同的硅学筛选评估,结果表明这些化合物具有最佳的理化特性,是优秀的先导分子。最后,利用分子对接研究对体外结果进行了验证,发现了在 AKT 活性部位的结合相互作用。
