Abstract
In present study, seventeen α-nitrile substituted guaiazulene-based chalcone derivatives including twelve new were designed, synthesized, and assayed for antiviral, cytotoxicity and signal pathway activities. All derivatives showed potential antiviral activity towards influenza virus or herpes simplex virus (HSV), 7 g with the substitution of nitro group showed strong effects towards H1N1 virus at 30 μM with inhibitory rate of 66.0%, 7o with thiophene exhibited potent anti HSV-1 activities with inhibitory rate of 65.8%. Moreover, several compounds exhibited inhibitory effects on tumor cells and hypoxia-inducible factor-1 (HIF1) signaling pathways. These results showed that α-nitrile substituted guaiazulene-based chalcones offered a promising framework for the further development of new highly efficient drugs.
