5-FU prodrugs, which were divided into three series of compounds, A, B, and C. The chemical structures of these prodrugs are confirmed by using FTIR, 1H-NMR, 13C-NMR, and mass spectrophotometers. The chemical stability of these prodrugs in simulated gastric and intestinal fluids as well as their release in human serum were measured spectrophotometrically. The outcomes showed that the synthetic prodrugs
5-氟尿嘧啶 (5-FU) 常被用作癌症治疗中的化疗药物。然而,由于其显着的副作用、有限的选择性和肿瘤耐药性,5-FU的治疗用途受到质疑。为了改变5-FU的理化性质并提高其靶向性,采用香豆素基酯酶敏感的前药系统制备了9种5-FU前药,分为A、B和三个系列化合物。 C.这些前药的化学结构通过FTIR、1H -NMR、13C -NMR和质谱仪确认。通过分光光度法测量这些前药在模拟胃液和肠液中的化学稳定性以及它们在人血清中的释放。结果表明,合成前药在两种受刺激的液体中具有非凡的稳定性,半衰期相对较高,表明它们可以穿过胃肠道上部而不会受到伤害。所产生的前药在人血清中的半衰期为 391.30 至 517.94 分钟,表明它们能够完好无损地进入靶组织并以伪一级动力学释放其活性成分。这些成分包括 5-FU、香豆素或其一种衍生物,以及一种 5-FU 生化修饰剂,即 Legumain 特异性三肽、二氯乙酸盐
