anti-tumor action, four of them showed the same anti-tumor potency as that of cytarabine. The preliminary toxicity evaluation revealed that the LD50 values of 6a–p should be more than 500 mg/kg. With CT DNA as model system an intercalating mechanism was explored. Using 3D QSAR analysis the relationship of the in vivo anti-tumor activity and the structure was quantitatively described. By docking 6a–p
合成了16种新型N-(3-羧基-9-苄基-β-咔啉-1-基)乙基氨基酸(6a - p)作为嵌入的先导化合物。在体外细胞毒性试验中,它们对五种人类癌细胞系的IC 50值范围为10.95μM至约400μM。在S180小鼠模型上,其中8个具有抗肿瘤作用,其中4个具有与阿糖胞苷相同的抗肿瘤能力。初步毒性评估表明,LD 50值为6a – p应超过500 mg / kg。以CT DNA为模型系统,探索了一种嵌入机制。使用3D QSAR分析定量描述了体内抗肿瘤活性与结构的关系。通过将6a – p与d(CGATCG)2寡核苷酸对接,证明了嵌入。
