Derivatives of the new ringsystem pyrrolizino[2,3-b]indol-4(5H)-one were prepared in four steps starting from substituted benzonitriles bearing a functionalized amino group in the adjacent position. The unsubstituted- and the dimethoxy-pyrrolizinoindolones 5a and 5b exhibited modest activity against the HL-60(TB) human leukemia cell line, whereas the N-methylated dimethoxy-pyrrolizinoindolone 6b showed
新的环系统吡咯烷并[2,3 - b ]吲哚-4(5 H)-one的衍生物是从相邻位置带有官能团氨基的取代苄腈开始,分四个步骤制备的。未取代的和二甲氧基吡咯烷酮吲哚酮5a和5b对HL-60(TB)人白血病细胞系表现出适度的活性,而N-甲基化的二甲氧基吡咯烷酮吲哚酮6b对MOLT-4白血病,A549 / ATCC具有选择性, HOP-92和NCI-H460非小细胞肺癌以及CAKI-1肾癌细胞系。
