The natural product oridonin has the potential to be a broad-spectrum antineoplastic agent. To develop oridonin analogues with high potency, a series of novel oridonin analogues were designed and synthesized by removing the multiple hydroxyl groups of parent compound. The representative analogues 14, 19, and 26 exhibited potent anticancer effects against K562, MDA-MB-231, SMMC-7721, and MCF-7 cells
天然产物冬凌草素具有成为广谱抗肿瘤剂的潜力。为了开发高效的冬凌草苷类似物,通过去除母体化合物的多个羟基,设计并合成了一系列新型冬凌草苷类似物。代表性的类似物 14、19和26对K562 、MDA-MB-231、SMMC-7721 和 MCF-7 细胞表现出有效的抗癌作用。对其 14-OH 的进一步结构修饰分别产生更有效的衍生物16n、21d和28d ,其中化合物16n的 IC 50值比 K562 细胞中的亲本冬凌草皂苷强 50 倍。此外,复合16n显着诱导K562细胞在G2期的细胞周期停滞并增加凋亡细胞的比例。重要的是,化合物16n、21d和28d在体内H22 同种异体移植小鼠中表现出良好的抗肿瘤活性。这些结果表明化合物16n、21d和28d值得进一步开发作为治疗癌症的有希望的候选者。
