anti-hormonal therapy, the development of new antineoplastic drugs is necessary. Lawsone (2-hydroxy-1,4-naphtoquinone) is a natural bioactive naphtoquinone displaying a range of activities, with dozens of derivatives described in the literature, including some glycosides possessing antitumor activity. Here, a series of glycosides of lawsone are reported for the first time and all compounds displayed good activity
乳腺癌是女性中发病率最高且致命的癌症类型,到2020年,全世界估计有200万例新病例,其中60万人死亡。由于并非所有类型的乳腺癌都对抗激素疗法产生反应,因此有必要开发新的抗肿瘤药。Lawsone(2-hydroxy-1,4-naphtoquinone)是一种天然的生物活性萘醌,具有多种活性,文献中描述了数十种衍生物,包括一些具有抗肿瘤活性的糖苷。在这里,首次报道了一系列的Lawsone苷,并且所有化合物都显示出对SKBR-3细胞系的良好活性,IC50低于10 µM。最有希望的衍生物是衍生自过乙酰化d-葡萄糖的糖基三唑(11),它对SKBR-3具有更好的细胞毒性(IC50 = 0.78 µM),对这种肿瘤细胞具有最高的选择性(SI> 20)。这项工作中描述的所有化合物都比劳森酮更具活性,表明碳水化合物和糖基三唑部分对于活性很重要。
