Cusculine
Based on 1 Customer Validation
Cusculine (FAC21) is an oropouche virus (OROV) endonuclease inhibitor with an IC50 of 1.4 μM. Cusculine strongly interacts with OROV endonuclease, possibly limiting viral RNA interaction with other proteins, intercalates into double-stranded RNA (a viral replication intermediate), and efficiently inhibits OROV viral replication in vitro. Cusculine can be used for the research of oropouche fever.

Cusculine (FAC21) (72 h) exhibits low cytotoxicity in Vero cells (CC50 = 1640 μM)[1].
Cusculine (15.125-250 μM) potently inhibits OROV infection in Vero cells (EC50 = 33.03 μM)[1].
Cusculine (125 μM; 8-48 hpi) strongly inhibits OROV replication early in Vero cells (99.9% inhibition at 8 hpi)[1].
Cusculine (18.5 μM; 45 min) modestly interacts with dsRNA, showing partial intercalation activity[1].
Cusculine (0-90 μM; 10 min) potently inhibits OROV N-terminal endonuclease as a competitive inhibitor (IC50 = 1.4 μM)[1].
Cusculine stably binds to the active site of OROV N-terminal endonuclease, with favorable binding free energy and conserved interacting residues[1].
