Derivatives of the new ring system indolo[1,2-c]benzo[1,2,3]triazine 5 were synthesized by diazotization of substituted 2-(2-aminophenyl)indoles followed by an intramolecular coupling reaction of the diazonium group with the indole nitrogen. To obtain the indolobenzotriazine system it was necessary to protect the 3 position of the indole nucleus to avoid cyclization into the indolo[3,2-c]cinnoline
新的环系统吲哚[1,2-c]苯并[1,2,3]三嗪5的衍生物是通过将取代的2-(2-氨基苯基)吲哚重氮化,然后将重氮基团与环己基进行分子内偶联反应而合成的。吲哚氮。为了获得吲哚并苯并三嗪系统,必须保护吲哚核的3位以避免环化成吲哚并[3,2-c] cinnoline系统4。在体外评估了吲哚并三嗪5a-g对一组白血病的抗肿瘤活性。 -,淋巴瘤,癌和神经母细胞瘤衍生的细胞系。一些化合物在亚微摩尔浓度下抑制T和B细胞系的增殖,而它们对实体肿瘤细胞系的活性则在微摩尔范围内。当评估其5a,d的抗真菌潜力可抑制某些测试的真菌,尽管浓度非常接近抑制人细胞增殖的浓度。相反,所有吲哚苯并三嗪被证明是相当有效和选择性的链球菌和葡萄球菌抑制剂。特别地,5b,c,g的效力比参考药物链霉素高80倍,并且以远低于对动物细胞的细胞毒性的浓度抑制上述革兰氏阳性细菌的生长。
