Nanoparticle-delivered quercetin for cancer therapy.

Quercetin, a natural protective bioflavonoid, possesses diverse pharmacologic effects, such as antioxidant, anti-inflammatory, anti-proliferative, and anti-angiogenic activities. Recently, quercetin's effect in cancer prevention and treatment was recognized. However, the poor water solubility and low-bioavailability of quercetin limit its clinical use in cancer therapy. Nanotechnology provides a method to create novel formulations for hydrophobic drug. Nanoparticles-delivered quercetin has attracted many attentions for its enhanced anticancer potential and promising clinical application. This review will discuss the application of nanotechnology in quercetin delivery for cancer therapy.
