Singlet oxygen quantum yields, DNA binding and cleavage, topoisomerase II inhibition and photodynamic therapy activities of two cationic BODIPY derivatives (BODIPY-3a and BODIPY-6a) were examined utilizing different methods. The singlet oxygen quantum yield values of compounds were found to be 0.07 and 0.13 in TBS. BODIPY-3a and BODIPY-6a interacted with CT-DNA with Kb values of 5.18±(0.15) × 103 and
通过将BODIPY 2和5与3,4-双3- [3- [3-(二甲基氨基)苯氧基]丙氧基}进行Knoevenagel缩合反应,制得一系列新的BODIPY 3和6,在其3,5-位具有两个二甲基氨基和二乙基氨基部分。苯甲醛和4- 3- [3- [3-(二甲基氨基)苯氧基]丙氧基}苯甲醛。通过在DMF中用过量的CH 3 –I处理BODIPY 3和6来合成水溶性BODIPY-3a和BODIPY-6a。两种阳离子BODIPY衍生物(BODIPY-3a和BODIPY-6a)使用不同的方法进行了检查。在TBS中发现化合物的单重态氧量子产率值为0.07和0.13。BODIPY-3A和BODIPY-6A与CT-DNA与之交互ķ b的值5.18±(0.15)×10 3和2.88±(0.05)×10 3 中号-1,分别。琼脂糖凝胶电泳实验表明,BODIPY-3a和BODIPY-6a对超螺旋质粒DNA具有明显的
