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 (Koff). 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.

find a better hit compound with diverse binding modes, 16 biamides were designed with the help of docking program. They were then synthesized using one-pot four-component Ugireaction. 7e with selectivity index of more than 18.9 (50% effective concentration of 5.3 μM, but no cytotoxicity at 100 μM) and unique binding mode that could be dived into gatekeeper pocket was selected as a new hit compound.
