Abstract:

Zein shows great potential in anti-cancer drug delivery systems(DDS). However, the zein-based DDS prepared by the traditional method has its shortcomings, such as single function, uneven particle size, poor batch reproducibility and anti-cancer effect. In this work, the quercetin(chemical drug)-TCPP(photosensitizer) was used as the model drug(QT). The co-assembly of the carrier and the model drug was accurately controlled by microfluidic technology. And the HA-zein@QT nanodrug delivery system was precisely constructed to achieve the synergistic anti-tumor. Hyaluronic acid(HA) was used to functionalize α-zein to improve the biocompatibility, stability and cell uptake of the carrier. The microfluidic chip with a high mixing efficiency of 99.54% was screened by computer simulation. The average particle size and PDI of the prepared HA-zein@QT were (50.6±1.7) nm and 0.196, respectively. The results of stability experiments suggested that HA-zein@QT showed high stability after co-incubation with deionized water, PBS and 1640 medium. The results of reactive oxygen species and ·OH detection showed that the 1O2 and ·OH increased after exposure to near-infrared light. HA-zein@QT showed a low hemolysis rate(3.75%) after co-incubation with red blood cells. And a high survival rate(>84.57%) of non-tumor cells was obtained. This evidence indicated that the prepared DDS had high biocompatibility. The cytotoxicity experiment showed that the survival rates of A549, HCT116 and HCT8 cells were 28.2%, 20.2% and 24.6%, respectively. This indicated that HA-zein@QT had a high inhibitory ability to tumor cells. It is expected that the microfluidics precise construction of zein-based DDS will provide a new strategy for achieving high efficiency and minimal side effects in anti-tumor drug delivery.
