for their in vitro antitumor activity against seven human cancer cell lines. Compounds of 4a–e series showed a broad spectrum of antitumor activity, with GI50 values lower than 15 μM for five cell lines. The derivative 4b, having the N,N-dimethylaminophenyl group at C-1, displayed the highest activity with GI50 in the range of 0.67–3.20 μM. A high selectivity and potent activity were observed for some
一系列新型的1-(取代的苯基)-3-(2-氧代-1,3,4-恶二唑-5-基)β-咔啉(4a – e)和相应的曼尼希碱5 – 9(a – c合成)并评估其对七种人类癌细胞系的体外抗肿瘤活性。4a – e系列化合物显示出广泛的抗肿瘤活性,五个细胞系的GI 50值低于15μM。在C-1处具有N,N-二甲基氨基苯基的衍生物4b在GI 50下表现出最高的活性在0.67–3.20μM的范围内。观察到某些Mannich碱基具有较高的选择性和强活性,特别是对耐药卵巢(NCI-ADR / RES)细胞系(5a,5b,6a,6c和9b)和卵巢(OVCAR-03)细胞系(5b,图6a,6c,9a,9b和9c)。另外,通过使用UV和荧光光谱分析研究了化合物4b与DNA的相互作用。这些研究表明4b通过插入结合与ctDNA相互作用。
