摘要:

依据多靶点候选药物EMB-3, 作者设计了一系列环状磷酰胺氮芥-喹唑啉偶联物并对其肺癌和乳腺癌细胞株的抑制作用进行了评价。其中化合物6d活性最强, BT474乳腺癌细胞株的抑制活性达到了IC50 = 0.6 μM, EMB-3活性的8倍。以化合物6d为分子探针对其作用靶点进行确认, 结果显示其对表皮生长因子受体-1和表皮生长因子受体-2的酶抑制活性分别为18 nM and 78 nM。初步体内药物代谢实验发现单剂量口服给药化合物6d (10 mg/kg), 大鼠的体内代谢半衰期为1.7小时, 比先导物EMB-3稳定。以上研究结果表明: 化合物6d是一个对乳腺癌肿瘤株BT474具有明显抑制活性的化合物, 值得进一步研究。

Abstract:

A series of new cyclic phosphoramidate mustard-quinazolineconjugates were designed and synthesized based on the drug candidate EMB-3, a multi-target-directed ligand against tumor cells, and their anti-tumor activities were evaluated on breast cancer and lung cancer cells. Compound 6d exhibited the best anti-tumor performance with IC50 = 0.6 μM(8-fold of EMB-3) on BT474breast tumor cells. Compound 6d inhibited epidermal growth factor receptor (EGFR, biomarker for NSCLC) and human epidermal growth factor 2 (HER2, biomarker for breast cancer) with IC50 of 18 nM and 78 nM, respectively. The preliminary pharmacokinetic study revealed that 6d was more stable than EMB-3 during the in vivo metabolism. A single dose per os (PO) administration of 6d in rat model (10 mg/kg) resulted in a moderate t1/2of 1.7 h. These results indicated that compound 6d was a potential lead compound for the treatment of breast cancer.
