Norisocorydine
Norjuziphine ((-)-Norjuziphine) is an alkaloid found in the lotus flower (Nelumbo nucifera). Norjuziphine inhibits the melanogenesis of murine B16 melanoma 4A5 cells stimulated by Theophylline (HY-B0809) (IC50=14.4 μM). Norjuziphine is promising for research of skin whitening and related skin pigmentation disorders[1].
