Abstract:Objective:To compare the pharmacodynamics and the tissue distribution of chrysophanol loaded polybutylcyanoacrylate nanocapsules,chrysophanol-hydroxypropyl-β-cyclodextrin inclusion complex,chrysophanol liposomes and DMF dissolved chrysophanol in mice with cerebral ischemia reperfusion.Methods:Using the cerebral ischemia reperfusion injury model,determined the chrysophanol content in blood,brain,heart,kidney,liver,spleen,lung of mice;measured the activity of malondialdehyde (MDA),monoamine oxidase-B (MAO-B),nitric oxide (NO),nitric oxide synthase (NOS),lipofuscin (LF),acetylcholinesterase (AChE) in brain,the content of amino acid (AA) in brain and the content of lipofuscin (LF) in heart;observed the morphology of hippocampal.Results:The order of chrysophanol concentration in mouse tissues is:blood>brain>kidney>liver>heart>spleen>lung. Compared with chrysophanol DMF,chrysophanol concentrations of chrysophanol formulations (10.0,1.0,0.1 mg·kg-1dose groups) in brain,liver and blood tissues were significantly high (P<0.01~0.05) in a dose-dependent manner. At the same time,the aging-related enzymes’ activity and the pathological morphology in hippocampal area were improved to some extent.Conclusion:All the three chrysophanol formulations could enhance the anti-aging effects of chrysophanol in mice with cerebral ischemia reperfusion,with the possible mechanisms involving enhancement of chrysophanol content in brain,regulation of the activity of aging-related enzymes and improvement of the pathological morphology in hippocampi area.
