A lead compound 7 has antitumor effect, which was discovered by screening our small synthetic natural product-like compound (NPL) library. Based on the lead compound, a series of novel tricyclic diterpene analogs were synthesized and investigated for their activity against the growth of various tumor cell lines using the sulforhodamine B (SRB) assay. To our delight, most aromatic amide compounds exhibited
铅化合物7具有抗肿瘤作用,这是通过筛选我们的小型合成天然产物样化合物(NPL)库发现的。基于先导化合物,合成了一系列新颖的三环二萜类似物,并使用磺基罗丹明B(SRB)分析了它们对各种肿瘤细胞系生长的活性。令我们高兴的是,大多数芳香族酰胺化合物都比铅化合物具有更强的抗肿瘤活性。活性最高的化合物19(QW30)的平均IC 500.33μM,效力比前导化合物高15倍。与肿瘤细胞系相比,大多数具有有效抗肿瘤活性的化合物对正常人成纤维细胞(HAF)的毒性较小。特别是19,其在HAF和癌细胞系之间的选择性指数(SI)比阳性对照化合物鬼臼毒素高17.3倍。在T47D细胞系上进行了7和19的凋亡,集落形成和transwell迁移测定。该被检体内的抗肿瘤效果19在T47D荷瘤小鼠中也观察到无明显毒性。
