their advantages in cancer treatment. In present study, HDAC inhibitors pharmacophore and 2-methoxyestradiol(2ME2) were combined into a new hybrid molecule for the first time. Forty-seven 2ME2 derivatives were synthesized and evaluated for antiproliferative activity. In particular, compound 4s exhibited a dual inhibition of tubulin polymerization and HDAC (IC50 = 0.06 µM toward HDAC2) activity, as well
多靶点药物设计因其在癌症治疗中的优势而成为一个活跃的研究领域。本研究首次将HDAC抑制剂药效团和2-甲氧基雌二醇(2ME 2 )结合成一种新的杂化分子。合成了47 种 2ME 2衍生物并评估其抗增殖活性。特别是,化合物4s表现出对微管蛋白聚合和 HDAC(对 HDAC2 的 IC 50 = 0.06 µM)活性的双重抑制,以及针对六种癌细胞系 的最有效的细胞毒性 IC 50值为 0.37–4.84 µM。复合4s显着破坏微管网络,在 G2/M 期停滞细胞周期,诱导线粒体膜电位崩溃并最终导致 A549 细胞凋亡。值得注意的是,4s被发现有效地阻碍了 HUVEC 的管状形成,并抑制了 HUVEC 以及 A549 细胞的增殖、迁移和侵袭。此外,通过斑马鱼模型试验证明了抗血管生成和抗转移活性。所有这些有益的抗癌活性及其对非癌细胞的高选择性,表明4s可能值得考虑用于癌症治疗。
