  • Patent number: 9376420
    Abstract: 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.
