Abstract
In this study, the tanshinone ⅡA loaded albumin nanoparticles were prepared by high pressure homogenization method. The formulation was optimized by central composite design-response surface method (CCD-RSM), with the particle size, encapsulation efficiency, and drug loading as indexes to investigate their in vitro anti-tumor effect. The results showed that the prepared nanoparticles had uniformly spherical morphology and uniform particle size distribution. The average particle size, encapsulation efficiency and drug loading of nanoparticles were about (175.7± 3.07) nm, 90.8%±1.47% and 5.52%±0.09%, respectively. Tanshinone ⅡA loaded albumin nanoparticles showed a more powerful antitumor effect than free tanshinone ⅡA for human promyelocytic leukemia NB4 cells. The preparation method of the drug-loaded albumin nanoparticles was simple and easy, and can significantly improve the solubility of tanshinone ⅡA, so it was helpful to extend its application in therapies against hematological malignancies.
