RESUMEN

Objective To evaluate the in vitro dissolution characteristic of IPRN-NLC and to study its effects on B16F10 cells proliferation, melanin synthesis, and tyrosinase activity. Methods The dynamic dialysis was employed to compare the in vitro dissolution of IPRN and IPRN-NLC; MTT assay was used to detect the proliferation of B16F10; The tyrosinase activity was determined by L-DOPA-oxidation; The melain content was determined by GENMED Cell Melanin Quantitative Assay Kit. Results The accumulation dissolution of IPRN-NLC was 67.31% within 72 h, which showed sustained release; While the dissolution of IPRN-suspension, IPRN-physical mixture, and IPRN-DMSO were 53.34%, 90.30%, and 98.67%, respectively. The IPRN-NLC could significantly promote the proliferation, tyrosinase activity and melanin content compared with IPRN DMSO groups (P < 0.05) at the same concentration. Conclusion IPRN-NLC could increase the solubility of the drug with sustained release, and showed good cell biology intermiscibility, which could significantly increase the effects on B16F10 cells.
