bioactivities. However its relatively poor solubility limited its absorption and bioavailability. In this study, a novel series of CUR-peptide conjugates were designed and synthesized as PepT1-mediated transport drugs and their solubility, cellular uptakes and anti-tumor activities were evaluated. Ten compounds showed better water solubility than CUR due to the dipeptide moiety. Compared with CUR, compound 5e
姜黄素(CUR)是姜黄的天然黄色颜料,具有广泛的生物活性。然而,其相对较差的溶解度限制了其吸收和生物利用度。在这项研究中,设计并合成了一系列新的CUR-肽缀合物作为PepT1介导的转运药物,并评估了它们的溶解度,细胞摄取和抗肿瘤活性。由于二肽部分,十种化合物显示出比CUR更好的水溶性。与CUR相比,化合物5e的活性稍好,5d的活性与CUR相似。此外,化合物5d和5e在Caco-2细胞中可完成较高的细胞摄取,并通过添加PepT1典型底物甘氨酰肌氨酸(Gly-Sar)剂量依赖性地抑制。化合物5d和5e改善了PepT1介导的CUR吸收,而没有影响活性。这些新的CUR二肽缀合物可作为未来药物开发的有前途的先导化合物。
