Access to the original series of pyrido[1',2':1,2]imidazo[4,5-h]quinazoline was developed from a 1,3-dicarbonyl unit with some “N-C-N” bisnucleophilic reagents and the derivatives obtained were evaluated for in vitro cytotoxic activities against HL60 and A2780 cells. All compounds exhibited cytotoxic activitise on resistant cell lines (MDR+; HL60R and A2780R) with no resistance phenomena.
通过 1,3-二羰基单元与一些 "N-C-N "双亲核试剂,开发出了吡啶并[1',2':1,2]咪唑并[4,5-h]喹唑啉的原始系列,并评估了所获得的衍生物对 HL60 和 A2780 细胞的体外细胞毒性活性。所有化合物都对耐药细胞株(MDR+;HL60R 和 A2780R)表现出细胞毒性活性,且无耐药现象。
