Cancer cell membrane-modified biodegradable mesoporous silica nanocarriers for berberine therapy of liver cancer.

ABSTRACT: Berberine (Ber) is regarded as a new, active and natural anti-cancer product; however, its clinical application has been limited due to its low aqueous solubility, poor gastrointestinal absorption, short residence time and poor targeting abilities. Hence, we reported a biomimetic nanoparticle as a drug delivery system to surmount these obstacles. We fabricated disulfide (S-S)-bridged mesoporous organosilica nanoparticles (ss-MONs) for Ber loading, which possessed uniform morphology, controllable mesoporous properties, highly-efficient drug loading capacity and superior biocompatibility. More interestingly, ss-MONs exhibited effective biodegradability under glutathione conditions through the breakage of the disulfide bond in ss-MONs, which promoted the Ber release.
