Biological Activity
DALDA acetate carrys a net positive charge (3+) at physiological pH and is thus hydrophilic and more polar than morphine[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
DALDA acetate (0.1 and 1.0 μg/side; ICV; once) results in biphasic effects, with an initial suppression, an intermediate marked inhibition, followed by activation for horizontal movement, rearing and stereotypy times in rats[2].
