were designed, synthesized and evaluated as dual ERα/VEGFR-2 ligands. Most of the derivatives exhibited potent activities in both enzymatic and cellular assays. Structure-activity relationship studies showed that a hydrogen-bonding interaction in the head section is important factors for the enhancement of ERα-binding affinity. The most potent compound II-9OH, an analog of 2-(4-hydroxylphenyl)pyrimidine
ERα 和 VEGFR-2 都是癌症治疗的重要靶点。在这里设计、合成和评估了一系列 2, 4-二取代嘧啶衍生物作为双 ERα/VEGFR-2 配体。大多数衍生物在酶促和细胞测定中都表现出有效的活性。构效关系研究表明,头部的氢键相互作用是增强 ERα 结合亲和力的重要因素。最有效的化合物II-9OH是 2-(4-羟基苯基) 嘧啶的类似物,在 MCF-7 癌细胞中的效力是他莫昔芬的 19 倍,并且表现出最佳的 ERα 结合亲和力 (IC 50 = 1.64 μM)作为出色的 VEGFR-2 抑制(IC 50 = 0.085 μM)。此外,这种双靶向化合物II-9OH通过抑制 MCF-7 细胞中孕酮受体 (PgR) mRNA 的表达而发挥显着的抗雌激素作用,并且在 CAM 测定中也显示出明显的体内血管生成抑制作用。在用II-9OH处理后,在 MCF-7 细胞中观察到细胞凋亡的诱导和细胞迁移的减少,伴随着
