Predloženi izum odnosi se na nove derivate izoindolona formule (I),u kojoj R1 do R6 imaju značenja data u patentnim zahtjevima. Novi spojevi su prikladni kao antiaritmijski lijekovi s kardioprotektivnom komponentom za sprečavanje i za liječenje infarkta i za liječenje angine pektoris. Oni također preventivno inhibiraju patofiziološke procese povezane s razvojem ozljeda uzrokovanih ishemijom, posebno pojave kardijalnih aritmija uzrokovanih ishemijom i otkazivanja srca.
