“In rat brain synaptosomes, hyperforin inhibited high-affinity choline uptake with an IC(50) of 8.5 microM, whereas low-affinity uptake was not affected.”
“Infusion of a lower concentration of hyperforin (10 microM), however, increased striatal ACh release and lowered Ch levels.”
“Local infusion of hyperforin (100 microM) via the dialysis probe caused a delayed reduction of ACh release and a concomitant increase of Ch levels.”
