o-, m-, p-Phenylenediamines having 2,3,4-trihydroxy, 3,4 dihydroxy, and 4-hydroxybenzoyl moieties were prepared and their inhibitory activities were measured against topoisomerase I and II. More hydroxy groups on two aromatic rings increased the activities. Bis(trihydroxybenzoyl)-o-phenylenediamide showed IC(50)=0.90 and 0.09 microM against topoisomerase I and II, respectively. Compounds with hydroxy
制备具有2,3,4-三羟基,3,4-二羟基和4-羟基苯甲酰基的邻,间,对苯二胺,并测定其对拓扑异构酶I和II的抑制活性。两个芳环上的更多羟基增加了活性。双(三羟基苯甲酰基)-o-苯二酰胺显示对拓扑异构酶I和II的IC(50)= 0.90和0.09 microM。具有被乙酰基部分保护的羟基的化合物仍然具有活性。较少的羟基降低了它们的活性。苯并噻唑衍生物也表明其活性。
