Activity Information

Target Organism HPIV 3

Assay Plaque reduction assay

Activity

[Ref.28344321]Human parainfluenza viruse 3(HPIV 3): inhibition of virus infection in Vero cells(IC90=0.7 ± 0.26 nM,IC50=0.015 ± 0.07 nM).

Cytotoxicity

[Ref.28344321]Vero cells: CC50+10000 nM.

Binding Target membrane

Mechanism Peptides derived from the HRC of paramyxovirus F proteins interfere with formation of the six-helix bundle in a dominant-negative manner by binding to the transiently exposed HRN coiled coil in the transient fusion intermediate, thereby inhibiting membrane fusion.
