Description_x000D_ Packaging_x000D_ 10 mg in glass bottle_x000D_ Biochem/physiol Actions_x000D_ Cyclo-Gly-Pro is a neuro-protective compound, an endogenous diketopiperazine, which enhances memory. In the animal model of PD, the compound improved functional recovery when administered after the onset of dyskinesia. It appears that the compound recovery function may result from non-proliferative neurogenesis that results from the inhibition of apoptosis of stem cells and/or the promotion of neuronal-orientated proliferation in the SVZ (subventricular zone).
