Abstract

Aim This study aimed to synthesise quercetin- caffeic-acid phenethyl ester (CAPE)-co-loaded poly(lactic-co-glycolic-acid) (PLGA) nanoparticles (QuCaNP) and investigate their anti-cancer activity on human colorectal carcinoma HT-29 cells. Methods QuCaNPs were synthesised using single-emulsion (o/w) solvent evaporation method. Particle size, zeta potential, polydispersity index, in vitro release profile, and surface morphology of QuCaNPs were determined. Cytotoxicity, anti-migration, anti-proliferation and apoptotic activities of QuCaNPs were studied. Results Mean diameter of QuCaNP was 237.8 +/- 9.670 nm, with a polydispersity index (PDI) of 0.340 +/- 0.027. Encapsulation efficiency was 74.28% (quercetin) and 65.24% (CAPE). Particle size and drug content of QuCaNP remained stable for 30 days at -20 degrees C. The half-maximal inhibitory concentration (IC50) values of QuCaNP-treated HT-29 cells were calculated as 11.2 mu g/mL (24 h) and 8.2 mu g/mL (48 h). QuCaNP treatment increased mRNA levels of caspase-3 (2.38 fold) and caspase-9 (2-fold) and expressions of key proteins in the intrinsic apoptosis pathway in HT-29 cells. Conclusion Overall, our results demonstrated QuCaNPs exhibits improved anti-cancer activity on HT-29 cells.
