An efficient synthesis of 2-hydroxy-6-methylbenzo[b][1,6]naphthyridin-1(2H)-one was devised. The hydroxy group was alkylated, acylated and replaced by hydrogen. Electrophilic nitration, bromination and chlorosulfonation occurred readily in the 4-position. From the last, various sulfonamide derivatives were prepared. A selection of the products was screened by the National Cancer Institute. Cytotoxicities
设计了2-羟基-6-甲基苯并[ b ] [1,6]萘啶-1(2 H)-one的有效合成方法。羟基被烷基化,酰化并被氢取代。在4-位容易发生亲电硝化,溴化和氯磺化。从最后开始,制备了各种磺酰胺衍生物。国家癌症研究所筛选了一些产品。细胞毒性一般较低。
