| 摘 要： | <正>A series of novel 7'-azaindirubin(1a-g) and 7-azaindirubin(2a,2c,2e and 2f) derivatives were designed and synthesized.Their structures were characterized by ~1H NMR and MS spectroscopy as well as by elemental analysis.Their inhibitory properties against CDK2/cylinA were evaluated in vitro.In contrast to indirubin,some of the described azaindirubins emerged as potent inhibitors of CDK2/cylinA and compound 2b had more potent activity.Biological tests also showed that nitrogen atom at 7-position of azaindirubin was more beneficial to enhance the kinase inhibitory activity.
