摘 要
肿瘤是严重威胁人类健康的疾病,传统抗肿瘤药物存在选择性差、毒副作用大等问题,因此设计新型抗肿瘤药物具有重要意义。本研究旨在通过分子设计开发新型抗肿瘤药物并探究其作用机制。基于计算机辅助药物设计技术,结合量子化学计算与分子对接方法筛选出一系列潜在的抗肿瘤化合物。这些化合物以特定靶点为作用对象,如某些关键蛋白或信号通路中的分子,经过体外细胞实验和体内动物模型实验验证,发现部分化合物对多种肿瘤细胞具有显著的抑制效果,且对正常细胞毒性较低。其中一种化合物可特异性地与靶点蛋白结合,阻断信号传导路径,诱导肿瘤细胞凋亡,这是本研究的重要创新点。该成果不仅为抗肿瘤药物的研发提供了新的思路和方向,也为深入理解抗肿瘤药物的作用机制奠定了基础,有望推动抗肿瘤药物向更高效、低毒的方向发展。

Abstract
Cancer poses a significant threat to human health, and traditional anticancer drugs suffer from issues such as poor selectivity and severe toxic side effects. Therefore, the design of novel anticancer drugs is of great significance. This study aims to develop new anticancer drugs through molecular design and investigate their mechanisms of action. Leveraging computer-aided drug design technology combined with quantum chemical calculations and molecular docking methods, a series of potential anticancer compounds were screened. These compounds target specific entities, such as key proteins or molecules in critical signaling pathways. After validation through in vitro cell experiments and in vivo animal model studies, some of these compounds exhibited significant inhibitory effects on various cancer cells while demonstrating low toxicity to normal cells. Notably, one compound specifically binds to the target protein, blocking the signal transduction pathway and inducing apoptosis in cancer cells, which represents a crucial innovation in this research. This achievement not only provides new insights and directions for the development of anticancer drugs but also lays a foundation for a deeper understanding of the mechanisms of action of these drugs, potentially advancing the development of more efficient and less toxic anticancer therapies.
