MK-2748 is a hepatitis C virus (HCV) NS3/4a protease inhibitor. MK-2748 exhibits broad-spectrum and potent antiviral activity, with nanomolar-level activity against all genotypes (gt1a-gt6) (IC₅₀ < 0.115 nM), showing only slightly weaker activity against gt3a (1.212 nM), and maintaining high inhibitory activity against drug-resistant mutant strains such as gt1b R155K (IC₅₀ = 0.032 nM) and D168Y (IC₅₀ = 0.057 nM). MK-2748 can be used in the research of HCV infection.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
