Abstract:
Puerarin (Pur) is herbal medicine that its inflammatory response but low solubility to reduce activity. Thus, the aim of this study was to synthesize q188-kappa-carrageenan@Pur@gold nanoparticles (q188-κ-c@Pur@AuNPs) for enhancing solubility and transdermal delivery. The κ-c was synthesized by quaternization of κ-c with 25% (v/v) q188, and the q188-κ-c @AuNPs was prepared by reducing HAuCl4 into AuNPs by using 25% (v/v) q188-κ-c as reducing and stabilizing agents. The highest degree of quaternization (%DQ) at 21.12% was found q188 addition, which was calculated from 1H NMR. The solubility of the q188-κ-c derivatives was 43.7±0.01%, which higher than κ-c. The size of synthesized q188-κ-c@AuNPs was confirmed by UV-vis, TEM, EDX and DLS, which were found the successfully synthesized with the size 15 nm. A cytotoxic study of Pur loaded on q188-κ-c-@AuNPs derivatives (q188-κ-c-@Pur@AuNPs) were observed, which shown increasing cytotoxicity to CLS cells and non-toxic to normal cells (Wi-38) by MTT assay. In vitro drug permeation was studied by Franzs cell method. The q188-κ-c-@Pur@AuNPs permeation was investigates by ICP-OES and UV-vis that shown increasing permeation to across cellulose membrane. According to the results, it was suggested that q188-κ-c@Pur@AuNPs can be a good candidate to further development for transdermal delivery applications.
