Abstract

This work examines the capacity of Naringin and Rutin to influence the DNA damage response (DDR) pathway by investigating their interactions with key DDR proteins, including PARP-1, ATM, ATR, CHK1, and WEE1. Through a combination of in silico molecular docking and in vitro evaluations, we investigated the cytotoxic and genotoxic effects of these compounds on MDA-MB-231 cells, comparing them to normal human fibroblast cells (2DD) and quiescent fibroblast cells (QFC). The research found that Naringin and Rutin had strong affinities for DDR pathway proteins, indicating their capacity to specifically regulate DDR pathways in cancer cells. Both compounds exhibited preferential cytotoxicity towards cancer cells while preserving the vitality of normal 2DD fibroblast cells, as demonstrated by cytotoxicity experiments conducted at a dose of 10 µM. The comet experiments performed particularly on QFC cells provide valuable information on the genotoxic impact of Naringin and Rutin, highlighting the targeted initiation of DNA damage in cancer cells. The need to use precise cell models to appropriately evaluate toxicity and genotoxicity is emphasized by this discrepancy. In addition, ADMET and drug-likeness investigations have emphasized the pharmacological potential of these compounds; however, they have also pointed out the necessity for optimization to improve their therapeutic profiles. The antioxidant capabilities of Naringin and Rutin were assessed using DPPH and free radical scavenging assays at a concentration of 10 µM. The results confirmed that both compounds have a role in reducing oxidative stress, hence enhancing their anticancer effects. Overall, Naringin and Rutin show potential as medicines for modulating the DDR in cancer treatment. They exhibit selective toxicity towards cancer cells while sparing normal cells and possess strong antioxidant properties. This analysis enhances our understanding of the therapeutic uses of natural chemicals in cancer treatment, supporting the need for more research on their mechanisms of action and clinical effectiveness.

摘要

这项工作通过研究柚皮苷和芦丁与关键 DDR 蛋白(包括 PARP-1、ATM、ATR、CHK1 和 WEE1)的相互作用,考察了它们影响 DNA 损伤反应 (DDR) 途径的能力。通过计算机模拟分子对接和体外评估的结合,我们研究了这些化合物对 MDA-MB-231 细胞的细胞毒性和遗传毒性作用,并将其与正常人类成纤维细胞(2DD)和静止成纤维细胞(QFC)进行了比较。研究发现,柚皮苷和芦丁与 DDR 途径蛋白具有很强的亲和力,表明它们有能力特异性调节癌细胞中的 DDR 途径。这两种化合物在 10 μM 剂量的细胞毒性实验中均表现出对癌细胞的优先细胞毒性,同时保持正常 2DD 成纤维细胞活力。在 QFC 细胞上进行的彗星实验提供了关于柚皮苷和芦丁遗传毒性影响的有价值信息,突出了在癌细胞中靶向引发 DNA 损伤。这种差异强调了需要使用精确的细胞模型来适当评估毒性和遗传毒性。此外,ADMET 和药物相似性研究强调了这些化合物的药理学潜力;然而,它们也指出需要进行优化以改善它们的治疗谱。在 10 μM 浓度下,通过 DPPH 和自由基清除测定评估了柚皮苷和芦丁的抗氧化能力。结果证实,这两种化合物都具有减轻氧化应激的作用,从而增强其抗癌作用。总的来说,柚皮苷和芦丁具有作为调节癌症治疗中 DDR 的药物的潜力。它们对癌细胞具有选择性毒性,同时对正常细胞具有保护作用,并且具有很强的抗氧化特性。这项分析增强了我们对癌症治疗中天然化学物质治疗用途的理解,支持对其作用机制和临床效果进行更多研究的必要性。
