In Vitro

Cyclopropavir exhibits antiviral activity against HCMV in human foreskin fibroblasts (HFFs) and mouse embryo fibroblasts (MEFs)^[1].
Cyclopropavir (15 µM) inhibits UL97 kinase activity in COS7 cells transfected with UL97 and pp65-GFP fusion protein, as shown by increased formation of nuclear aggresomes^[2].
Cyclopropavir (2.5 µM; 5 days) achieves a shorter half-life compared to Ganciclovir (HY-13637) in HCMV-infected human foreskin fibroblasts (HFFs)^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Cyclopropavir (1-10 mg/kg; p.o.; 5-28 days) reduces mortality and viral titers in BALB/c mice and SCID mice infected with MCMV^[4].
Cyclopropavir (10-30 mg/kg; p.o.) prevents mortality, mitigates liver/lung pathology, and reduces viral replication in immunosuppressed Syrian hamsters infected intravenously or intranasally with HAdV6^[5].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
