    摘要: There is provided novel substituted 4-aryl-3-hydroxyquinolin-2-one derivatives of the formula ##STR1## wherein R is hydrogen or methyl;R.sup.1, R.sup.2, R.sup.3 and R.sup.4 each are independently hydrogen, bromo, chloro or trifluoromethyl, and when R.sup.1, R.sup.3 and R.sup.4 are hydrogen, R.sup.2 is nitro;R.sup.5 is hydrogen or methyl; andR.sup.6 is bromo or chloro;or a nontoxic pharmaceutically acceptable salt thereof, which are openers of the large-conductance calcium-activated potassium channels and are useful in the treatment of disorders which are responsive to the opening of the potassium channels.
