such as tamoxifen. Although these drugs have showed great benefits in the treatment of breast cancer, the risk of endometrial cancer and endocrine resistance restrict their use. The reasonable designing of multi-target drugs can decrease the side effects and improve the tolerance of antineoplastic agents Studies have identified that VEGFR-2 plays a pivotal role in tumor angiogenesis and drug resistance
SERM是一系列重要的小分子化合物,可调节雌激素受体,例如他莫昔芬。尽管这些药物在乳腺癌的治疗中显示出巨大的益处,但是子宫内膜癌和内分泌抵抗的风险限制了它们的使用。合理设计多靶标药物可以减少副作用并提高抗肿瘤药的耐受性研究发现,VEGFR-2在肿瘤血管生成和耐药性中起着关键作用。此外,据报道,他莫昔芬与低剂量的VEGFR-2抑制剂联合使用可最大程度地提高治疗效果并延缓SERM抗药性肿瘤的生长。在这项工作中,设计了一系列针对ERα和VEGFR-2的3-芳基-喹啉衍生物,以消除SERM的缺点。我们确定了化合物12f13f和13f显示出高度的ERα结合亲和力和相对强度的VEGFR-2抑制活性。此外,这两种化合物对MCF-7和HUVEC细胞系均表现出优异的抗增殖活性,且其微摩尔IC 50(1–8μM)低。进一步的研究证实,化合物13f可以降低PgR mRNA的表达,阻止MCF-7乳腺癌细胞的细胞周
