title: [Tendency of development on novel type of cardiotonic drugs].
abstract: The narrow margin of safety of cardiotonic glycosides has led to extensive studies for novel cardiotonic agents that are superior to the glycosides. Cardiotonic drugs acting on beta-adrenoceptors and inhibitors of cAMP phosphodiesterase have been extensively studied and used for the treatment of heart failure. Ca sensitizers are of interest, since such a mechanism of action may be beneficial for the failing heart. Recently, cardiotonic substances with a novel mechanism of action such as gingerol and xestoquinone have been isolated from natural sources. Furthermore, 9-methyl-7-bromoeudistomin D, a powerful radiolabeled Ca2+ releaser having caffeine-like properties, may provide a promising tool for studying the molecular mechanism of the Ca2+ release process.
