BioAssay: AID 455703

Noncompetitive inhibition of recombinant influenza A virus rvH1N1 A/Bervig_Mission/1/18 neuraminidase

Five flavonols (3, 5, and 9-11) were isolated from Rhodiola rosea, and compared with commercially available flavonoids (1, 2, 4, 6-8, and 12-14) to facilitate analysis of their structure-activity relationship (SAR). All compounds (1-14) showed neuraminidase inhibitory activities with IC(50) values ranging from 0.8 to 56.9 microM. The in vitro anti-influenza virus activities of flavonoids 1-6, more ..

Title: Neuraminidase inhibitory activities of flavonols isolated from Rhodiola rosea roots and their in vitro anti-influenza viral activities.

Abstract: Five flavonols (3, 5, and 9-11) were isolated from Rhodiola rosea, and compared with commercially available flavonoids (1, 2, 4, 6-8, and 12-14) to facilitate analysis of their structure-activity relationship (SAR). All compounds (1-14) showed neuraminidase inhibitory activities with IC(50) values ranging from 0.8 to 56.9 microM. The in vitro anti-influenza virus activities of flavonoids 1-6, 8-12, and 14 were evaluated using two influenza viral strains, H1N1 (A/PR/8/34) and H9N2 (A/Chicken/Korea/MS96/96), testing their ability to reduce virus-induced cytopathic effect (CPE) in MDCK cells. We found that the activity of these compounds ranged from 30.2 to 99.1 microM against H1N1- and 18.5 to 133.6 microM against H9N2-induced CPE. Of compounds 1-14, gossypetin (6) exhibited the most potent inhibitory activity, with IC(50) values of 0.8 and 2.6 microM on neuraminidases from Clostridium perfringens and recombinant influenza virus A (rvH1N1), respectively. In contrast, kaempferol (3) exhibited the highest activity against two influenza viruses, H1N1 and H9N2 with EC(50) values of 30.2 and 18.5 microM, respectively. Activity depended on the position and number of hydroxy groups on the flavonoids backbone. In kinetic studies, all isolated compounds behaved as noncompetitive inhibitors.
