Breast cancer is a common malignant tumor, which mostly occurs in female population and is caused by excessive proliferation of breast epithelial cells. Breast cancer can cause nipple discharge, breast lumps and other symptoms, but these symptoms lack certain specificity and are easily confused with other diseases, thus affecting the early treatment of the disease. Once the tumor progresses to the advanced stage, distant metastasis can occur, leading to dysfunction of the affected organs, and even threatening the patients' lives. In this study, we synthesized high drug-loading gel particles and applied them to control the release of insoluble drugs. This method is simple to prepare, cost-effective, and validates their potential in breast cancer therapy. We first characterized the morphology and physicochemical properties of gel loaded with newly synthesized compound 1 by scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR), and thermal gravimetric analysis (TGA). Using newly synthesized insoluble compound 1 as a model drug, its efficacy in treating breast cancer was investigated. The results showed that hydrogel@compound 1 was able to significantly inhibit the proliferation, migration and invasion of breast cancer cells. Additionally, we utilized machine learning to screen three structurally similar compounds, which showed promising therapeutic effects, providing a new approach for the development of novel small-molecule drugs.
乳腺癌是一种常见的恶性肿瘤,主要发生在女性人群中,是由乳腺上皮细胞过度增殖引起的。乳腺癌可引起乳头溢液、乳房肿块等症状,但这些症状缺乏一定的特异性,容易与其他疾病混淆,从而影响疾病的早期治疗。一旦肿瘤进展到晚期,可能会发生远处转移,导致受影响器官的功能障碍,甚至威胁患者的生命。在这项研究中,我们合成了载药高的凝胶颗粒,并将其应用于控制难溶性药物的释放。该方法制备简单、成本效益高,验证了其在乳腺癌治疗中的潜力。我们首先通过扫描电子显微镜(SEM)、傅里叶变换红外光谱(FT-IR)和热重分析(TGA)对载有新合成化合物 1 的凝胶的形态和理化性质进行了表征。我们以新合成的难溶性化合物 1 为模型药物,研究了其治疗乳腺癌的疗效。结果表明,水凝胶@化合物 1 能够显著抑制乳腺癌细胞的增殖、迁移和侵袭。此外,我们利用机器学习筛选出三种结构相似的化合物,它们表现出有希望的治疗效果,为开发新型小分子药物提供了新的方法。
