Glabranine is a flavonoid isolated from Tephrosia species. Glabranine inhibits the dengue virus by interacting with the soluble extracellular domain of the DENV2 E protein. Glabranine can be used in research related to dengue virus inhibition, as well as for Glabranine antibacterial and antioxidant activities[1].
In vitro, Glabranine (6–50µM) was used to treat LLC-MK2 cells infected with dengue virus (serotype 2) for 24 hours. Glabranine exhibited no cytotoxicity to the cells and significantly inhibited dengue virus replication[2].
