substitutions at positions 1 and 3 of these hybrids was clearly addressed. Further, induction of apoptosis was confirmed by Annexin V‐FITC, Hoechst staining, and DNA fragmentation analysis. In addition, DNA photocleavage studies proved that two of the hybrids, (E)‐1‐(furan‐2‐yl)‐3‐(1‐(4‐(trifluoromethyl)phenyl)‐9H‐pyrido[3,4‐b]indol‐3‐yl)prop‐2‐en‐1‐one (7 d) and 1‐(3‐(furan‐2‐yl)‐5‐(1‐(4‐(trifluoromethyl)phenyl)‐9H‐pyrido[3
设计,合成并评估了一系列分别在C1和C3位置带有取代苯基和查耳酮/(N-乙酰基)-吡唑部分的β-咔啉杂化物。这些新的杂合分子表现出显著的细胞毒活性,用IC 50个值范围为<2.0μ中号至80μ中号,并与取代位置1和这些杂种显然解决的3相关联的结构-活性关系(SAR)。此外,膜联蛋白V-FITC,Hoechst染色和DNA片段分析证实了凋亡的诱导。此外,DNA光裂解研究证明其中两个杂种(E)-1(呋喃-2-基)-3-(1-(4-(三氟甲基)苯基)-9 H-pyrido [3,4- b ]吲哚-3-基)prop-2-en-1-one(7 d)和1-(3-(呋喃-2-基)-5-(1-(4- (三氟甲基)苯基)-9 H-吡啶基[3,4- b ]吲哚-3-基)-4,5-二氢-1 H-吡唑-1-基)乙酮(8 d)可以有效切割pBR322质粒DNA在用紫外线照射时。主动混合动力8 d抑制DNA拓扑异构酶
