The present invention relates to a novel bis-amide derivative compound or a pharmaceutically acceptable salt thereof; a method of preparation thereof; and a pharmaceutical composition for preventing or treating diseases caused by hepatitis C virus infection and health functional food for preventing or ameliorating diseases caused by hepatitis C virus infection, containing the bis-amide derivative compound or a pharmaceutically acceptable salt thereof as an active ingredient.
The novel bis-amide derivative compound of the present invention, particularly WJCPA-126, specifically binds to the catalytic site of CypA to effectively inhibit the activity of an isomerase, and the duration of the inhibitory effect can be increased because WJCPA-126 binds to CypA with high binding affinity exhibiting a low dissociation rate (K
off
). Accordingly, WJCPA-126 has nontoxic and non-immunosuppressive characteristics and can effectively inhibit HCV replication in vitro and in vivo model systems. Additionally, WJCPA-126 reactivates the host interferon response through an increase in the expression of IFN-stimulated genes (ISGs) and the inhibition of interleukin-8 (IL-8) secretion. Therefore, a series of the bis-amide derivatives including WJCPA-126 can be useful as a novel type CypA inhibitor exhibiting antiviral effect.
