Chroman derivatives exhibited potent inhibitory activity of NF-κB. For SAR, the chroman scaffold was modified with an indoline moiety. A series of indoline-2-carboxylic acid N- (substituted) phenylamide derivatives were synthesized to explore their inhibitory activities of NF-κB and they were also evaluated for cytotoxicity against various cancer cell lines. Since intermediates with Boc showed outstanding results, various substituents in place of ...
