The present invention relates to compounds of Formula I, or a pharmaceutically acceptable salt, ester, or prodrug, thereof:
which inhibit serine protease activity, particularly the activity of hepatitis C virus (HCV) NS3-NS4A protease. Consequently, the compounds of the present invention interfere with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a subject by administering a pharmaceutical composition comprising the compounds of the present invention.
The present invention provides a novel compound having an antiviral action, in particular, an HIV replication inhibiting action, as well as a pharmaceutical composition, in particular, an anti-HIV agent.

The present invention relates to a compound inhibiting HF-1 activity, a preparation method of the same, and a pharmaceutical composition comprising the same as an active ingredient. The compound of the present invention demonstrates anticancer activity not by non-selective cytotoxicity but by inhibiting the activity of HIF-1, the transcription factor playing an important role in cancer cell growth and metastasis. Accordingly, the compound or the pharmaceutically acceptable salt thereof according to the present invention inhibits HIF-1 activity, and therefore can be used as a therapeutic agent for solid tumors such as colon cancer, liver cancer, stomach cancer and breast cancer. In addition, the compound or the pharmaceutically acceptable salt thereof according to the present invention can be used as an active ingredient for a therapeutic agent for diabetic retinopathy or arthritis which may become worse when hypoxia-induced VEGF expression by HIF-1 increases.
