Cognitive enhancer effect of PHA 543613 in rat behavioral tests.
By Zsolt Bali on 02/14/2018
Assay Type: In Vivo
Species: Rat

We used PHA 543613 in behavioral pharmacology experiments and tested its cognitive enhancer effect. PHA 543613 was found effective in different behavioral paradigms, and in different models of cognitive impairment. For instance, PHA 543613 dose-dependently reversed scopolamine induced transient amnesia in the spontaneous alternation (t-maze) task of rats.

Sometimes we experienced poor solubility in physiological saline. Slight warming and ultrasonics might help.
