Gitoformate (INN, or pentaformylgitoxin, trade name Dynocard) is a cardiac glycoside, a type of drug that can be used in the treatment of congestive heart failure and cardiac arrhythmia (irregular heartbeat).[1] Produced by Madaus, it is not available in the US, and does not seem to be available in Europe either.


Gitoxigenin, the aglycon

Gitoformate is a derivative of the glycoside gitoxin, with five of the six free hydroxyl groups formylated, one on the aglycon and four on the sugar.[2][3] Gitoxin, a cardiac glycoside from the woolly foxglove (Digitalis lanata), has an aglycon of the cardenolide type named gitoxigenin, which is also the aglycon of lanatoside B, another Digitalis lanata glycoside.[4]
