A series of rhein derivatives (4a–x) were synthesized and evaluated for their aqueous solubility and in vitro anti-proliferative activities against six different tumor cell lines. The aqueous solubility of the compounds was in the range of 10.04 to 15.08 mg mL−1, which is 220 to 330-fold higher than that of rhein (0.0456 mg mL−1). All derivatives displayed more potent anti-tumor activity than rhein
合成了一系列大黄酸衍生物(4a–x),并评估了它们对六种不同肿瘤细胞系的水溶性和体外抗增殖活性。化合物的水溶解度在10.04至15.08 mg mL -1的范围内,比大黄酸(0.0456 mg mL -1)的水溶解度高220至330倍。所有衍生物都显示出比大黄酸更强的抗肿瘤活性,并且大多数衍生物甚至比5-FU更强,特别是4s,4t和4v(IC 50:在A549细胞上为3.01–5.28μM,在MCF-7细胞上为5.92–7.63μM,在HepG2细胞上为0.33–0.85μM,在HCT116上为0.31-0.83μM,在Bel-7402上为2.36–6.49μM,在Bel-7402上为4.48–7.31μM / 5-FU细胞)。还发现化合物4v通过下调HCT116细胞中的CDK1和细胞周期蛋白B诱导HCT116细胞凋亡和G2 / M期细胞周期停滞。我们的发现表明4v可能是未来研究的有希望的领先者。
