Biological Activity:
Aloin(Barbaloin) is a potent tyrosinase inhibitor with an IC50 of 97 µM for HeLaS3 cells. It is used as a stimulant-laxative, treating constipation by inducing bowel movements.It also shows a pronounced antiproliferative effect at physiological concentration, causes cell cycle arrest in the S phase, and markedly increases HeLaS3 cell apoptosis (to 24%). In the concentration range of 20-100 µM, its action was accompanied by remarkable changes in the activity of almost all antioxidant enzymes: MnSOD activity was increased many fold, while CuZnSOD and iNOS activities were inhibited. Moreover, inhibition of CuZnSOD was shown to occur by direct aloin interaction with the enzyme. [1][2]
