Biochem/physiol Actions

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).

The current study describes the neuroprotective effects of an endogenous diketopiperazine, cyclo-glycyl-proline (cyclic GP), in rats with hypoxic-ischemic brain injury and the pre-clinical development of an analogue, cyclo-L-glycyl-L-2-allylproline (NNZ 2591), modified for improved bioavailability. The compounds were given either intracerebroventricularly

Calcium plays a crucial role in many cellular processes. Its functions are directly dependent on the high specificity for Ca2+ exhibited by the proteins and ion carriers that bind divalent ions. To elucidate the basis for this specificity we have

This study was undertaken to isolate active secondary metabolites from immunostimulatory Alcaligenes faecalis FY-3 and evaluate their activities using grass carp Ctenopharyngodon idella kidney (CIK) cells. By applying chromatography techniques and successive recrystallization, three purified metabolites were obtained and identified
