benzyl, acetyl, or benzoyl groups was also investigated. The in vitro evaluation of cell growth inhibition on CCRF-CEM, HL-60, HeLa S3, and L1210 cell lines showed significant activity in 8 new compounds. The most potent compounds were the above mentioned 6-dibromomethyl derivative (IC(50)=0.54, 1.7, 5.0, and 1.9 molL(-1)) and 7,N(2),N(4)-tribenzyl-5H-pyrrolo[3,2-d]pyrimidine-2,4-diamine (IC(50)=1.9,
用KCN处理6-溴甲基-或6-二溴甲基-5-硝基嘧啶-2,4-二胺得到相同的产物-(2,6-二氨基-5-硝基嘧啶基)乙腈。腈在α-碳上苯甲酰化为氰基,优先提供相应的单苄基和二苄基衍生物,其还原环化反应生成7-苄基-5H-吡咯并[3,2-d]嘧啶-2,4-二胺和7,7-二苄基-7H-吡咯并[3,2-d]嘧啶-2,4,6-三胺。还研究了用苄基,乙酰基或苯甲酰基保护N(2)和N(4)原子的适用性。体外评估CCRF-CEM,HL-60,HeLa S3和L1210细胞系对细胞生长的抑制作用在8种新化合物中显示出显着活性。最有效的化合物是上述6-二溴甲基衍生物(IC(50)= 0.54、1.7、5.0和1.9 molL(-1))和7,
