Amyloid beta-peptide(25-35) is the fragment Aβ(25-35) of the Alzheimer's amyloid β-peptide, has shown neurotoxic activities in cultured cells. Amyloid beta-peptide(25-35) is also investigated in gel state for the first time. Comparative studies are also carried out using vibrational absorption and ECD. Amyloid beta-peptide(25-35) induces apoptotic effects on isolated brain mitochondria and the redox state of methionine-35.
In vivo, rats injected with Aβ25–35 peptide intracerebroventricularly and compound Danshen (CDS) are subsequently administered once daily for 23 days. The Alzheimer' s disease (AD) model group present with spatial learning and memory impairments. CDS and donepezil administration significantly ameliorate the Aβ25–35 peptide-induced memory impairment in both Morris water maze (P < 0.05) and passive avoidance task (P < 0.01) compared to the AD model group.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
