Abstract:

In the present work, we aimed to optimize the preparation technology of dimethyl curcumin niosomes, improve its solubility and assess its stability. The novel anti-androgen dimethyl curcuminniosomes were prepared by thin-film dispersion-ultrasonic method, and the prescription composition and preparation process were optimized by single-factor investigation method. Certainly, the solubility and quality evaluation of dimethyl curcumin niosomes were also investigated. The average particle size of prepared dimethyl curcumin niosomes was (310.3±0.9) nm. The highest encapsulation rate was 88.1%±1.7%, and the drug-loading amount was 4.03%±1.05%. Moreover, the leakage rate was below 2% within 45 d. Collectively, all these findings indicated that the niosomes, as a vector, could significantly improve the solubility and stability of dimethyl curcumin, offering a theoretical basis for dimethyl curcumin as an anticancer drug in medicine application.

Key words: Niosomes, Dimethyl curcumin, Thin-film dispersion-ultrasonic method, Encapsulation efficiency, Quality evaluation
