Description of Cusculine

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 [1].

In Vitro, 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].

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
