Báo cáo khoa học: Neuroprotective effects of naturally occurring polyphenols on quinolinic acid-induced excitotoxicity in human neuronsQuinolinic acid (QUIN) excitotoxicity is mediated by elevated intracellular

levels, and nitric oxide-mediated oxidative stress, resulting in DNA
damage, poly(ADP-ribose) polymerase (PARP) activation, NAD
+
deple-tion and cell death. We evaluated the effect of a series of polyphenolic
compounds [i.e. epigallocatechin gallate (EPCG), catechin hydrate, curcu-min, apigenin, naringenin and gallotannin] with antioxidant properties on
QUIN-induced excitotoxicity on primary cultures of human neurons....
