Stable conjugates: Two pivaloxymethyl (POM) groups were introduced at the 3‐ and 7‐hydroxy groups of quercetin to provide a 3,7‐bis‐O‐POM derivative (shown) with exceptional stability in cell culture media and efficient cellular uptake. Hydrolyzed to the 3‐O‐POM derivative in cytoplasm, the quercetin conjugate exhibits a significant cytostatic effect in various cancer cell lines.
稳定的结合物:在槲皮素的3和7-羟基上引入了两个新戊氧基甲基(POM)基团,以提供3,7- bis - O - POM衍生物(如图所示),在细胞培养基中具有出色的稳定性和有效的细胞摄取能力。槲皮素偶联物在细胞质中被水解成3‐ O‐ POM衍生物,在各种癌细胞系中均表现出显着的细胞抑制作用。
