Boosting the alkylation power of chalcones creates new anti-inflammatory agents. Thus NF-[small kappa]B-dependent proteins are inhibited and Nrf2-dependent ones activated. The activity enhancement relies solely and very effectively on the [small alpha]-substituent of the [small alpha],[small beta]-unsaturated carbonyl unit.
