Triple-negative breast cancer (TNBC) is the most aggressive cancers with a high recurrence rate and rapidly acquired drug resistance among various breast cancer subtypes. There is no specific drug for treatment of TNBC. Discovery of therapeutic agents with unique modes of actions is urgently needed. In this study, a series of seventy parthenolide derivatives was designed, synthesized, and evaluated
三阴性乳腺癌(TNBC)是最激进的癌症,其复发率高且在各种乳腺癌亚型中迅速获得耐药性。没有用于治疗TNBC的特定药物。迫切需要发现具有独特作用方式的治疗剂。在这项研究中,设计,合成和评估了一系列七十种单烯菊酯衍生物的抗TNBC活性。化合物7d对不同的乳腺癌细胞表现出最有效的活性,IC 50值在0.20μM至0.27μM范围内,与母体化合物小白菊内酯的IC 50值在2.68–4.63μM相比,提高了11.6至18.6倍。。值得一提的是7d比阳性对照药物ADR更活跃。此外,化合物7d可通过线粒体途径诱导SUM-159细胞凋亡,并引起SUM-159细胞G1期阻滞。这些发现表明,化合物7d作为最终发现有效的抗TNBC药物的先导化合物值得进一步研究。
