Effects of buthobendin and epinephrine on glycolytic energy formation and magnesium concentration in vitro and in vivo.

Abstract

Buthobendin activated glycolytic lactate formation stronger than epinephrine and increased the ATP level, both in vitro in rabbit myocardial slices and in vivo in rabbit blood. These effects were accompanied by an increase in extracellular magnesium concentration, which was probably related to the inhibitory effect of buthobendin on the membrane-bound ATPases.
