NXPZ-2 (Male ICR mice, 52.5/105/210 mg/kg, p.o., once daily for 7 days) improves AD mice learning and memorizing function including increased spontaneous alternation, increases number of active avoidance times, shortened escape latency, increased the time spent in the target quadrant and number of platform crossing[1]. NXPZ-2 (Male ICR mice, 52.5/105/210 mg/kg, p.o., once daily for 7 days) rescues the brain structure damage and lowers dead neuron numbers of AD mice with no obvious toxicity on mouse organs[1]. NXPZ-2 (Male ICR mice, 52.5/105/210 mg/kg, p.o., once daily for 7 days) alleviates oxidative stress by increasing Nrf2 expression levels, and promotes Nrf2’s cytoplasm to nuclear translocation, and improves cognitive dysfunction by elevating Nrf2 in both the central nervous system and peripheral blood[1]. Animal Model: Male ICR mice, AD model[1]. Dosage: 52.5 mg/kg, 105 mg/kg, 210 mg/kg. Administration: P.o., once daily for 7 days. Result: Showed statistically increased spontaneous alternation and no influence on basal motivation, displayed an increased number of active avoidance times, which improved the learning and memory ability of AD mice. Cell number and morphology in NPZX-2-treated groups were restored, dead neuron numbers of AD mice was lowered. Increased serum Nrf2 level, displays more Nrf2 in the hippocampal and cortical nucleus and less expression level in the hippocampal and cortical cytoplasm. Increased Nrf2-ARE binding in both hippocampus and frontal cortex, dose-dependently restored SOD, GSH, and MDA levels, and decreased AD marker protein (p-Tau)[1].
