This invention relates to new benzamide derivatives having a vasopressin antagonistic activity, etc. and represented by general formula (I):
wherein R1 is aryl optionally substituted with lower alkoxy, etc.,
R2 is lower alkyl, etc.,
R3 is hydrogen, etc.,
A is NH, etc.,
E is
etc.,
X is —CH═CH—, —CH═N—, or S, and
Y is a condensed heterocyclic group, etc.,
and pharmaceutically acceptable salts thereof, to processes for preparation thereof and to a pharmaceutical composition comprising the same.
The present invention provides selected dihydrobenzimidazolones which bind to the ubiquitously expressed E3 ligase protein cereblon (CRBN) and alter the substrate specificity of the CRBN E3 ubiquitin ligase complex, resulting in breakdown of intrinsic downstream proteins. The disclosed compounds are useful for the treatment of cancer.
