4,5-dihydro-1H-pyrazole derivative or salts thereof, and pharmaceutical composition comprising same

摘要

The present invention provides a 4,5-dihydro-1H-pyrazole derivative or its pharmaceutically acceptable salt, a process for the preparation thereof, and a pharmaceutical composition comprising the same. The 4,5-dihydro-1H-pyrazole derivative or its pharmaceutically acceptable salt effectively increases the LXR transcriptional activity, and therefore can be usefully applied for preventing or treating a dysfunction in cholesterol metabolism, such as cholesterol gallstone, hyperlipidemia, or coronary atherosclerosis.
