Alzheimer's disease (AD) is a growing concern in the modern society. The current drugs approved by FDA are not very promising. Rhynchophylline (RIN) is a major active tetracyclic oxindole alkaloid stem from traditional Chinese medicine uncaria species, which has potential activities beneficial for the treatment of AD. However, the application of rhynchophylline for AD treatment is restricted by the low water solubility, low concentration in brain tissue and low bioavailability. And there is no study of brain-targeting therapy with RIN. In this work, we prepared rhynchophylline loaded methoxy poly (ethylene glycol)-poly (dl-lactide-co-glycolic acid) (mPEG-PLGA) nanoparticles (NPS-RIN), which coupled with Tween 80 (T80) further for brain targeting delivery (T80-NPS-RIN).
