This invention relates to novel benzisoxazole derivatives that are found to be potent modulators of potassium channels and, as such, are valuable candidates for the treatment of diseases or disorders as diverse as those which are responsive to the modulation of potassium channels e.g. a respiratory disease, epilepsy or convulsions. X represents a substituent selected from the group consisting of CO—NR′R″, CO—O—R′, CO—NH—S, CO—NH—SO
