Nivitol
Based on 1 Customer Validation
Nivitol (UP302) is a natural phenolic compound discovered from Dianella ensifolia and also acts as a Tyrosinase inhibitor. Nivitol competitively and reversibly inhibits tyrosinase, suppressing melanin production. Nivitol inhibits homogentisate 1,2-dioxygenase (HGD). In human leukemia cells, Nivitol inhibits PI3K/AKT pathway phosphorylation, increases ROS, decreases mitochondrial membrane potential, and induces G2/M cell cycle arrest, apoptosis, and PINK1/Parkin-mediated mitophagy. Nivitol exhibits inhibition of tumor growth in the MV411 xenograft mouse model. Nivitol is used for research on exogenous ochronosis, hyperpigmentation, and leukemia.
