title: Synthesis and biological evaluation of 5-arylamino-6-chloro-1H-indazole-4,7-diones as inhibitors of protein kinase B/Akt.
abstract: A series of 5-arylamino-6-chloro-1H-indazole-4,7-diones were synthesized and evaluated for their inhibitory activity on protein kinase B/Akt. The compounds exhibited a potent Akt1 inhibitory activity. Further mechanistic study revealed that they might have dual inhibitory effects on both activity and phosphorylation of Akt1 in PC-3 tumor cell line.
