4-Methylumbelliferone is a hyaluronic acid (HA) synthesis inhibitor with an IC50 of 0.4 mM, which has antitumoral and antimetastatic effects. 4-Methylumbelliferone may inhibit the phosphorylation of HAS2 by PKC through the stimulation of O-GlcNAcylation; it also similarly ameliorates hypertriglyceridemia and hyperglycemia partly by modulating hepatic lipid metabolism and the antioxidant defense system along with increasing adiponectin levels. 4-methylumbelliferone is a hydroxycoumarin that is umbelliferone substituted by a methyl group at position 4. It has a role as a hyaluronic acid synthesis inhibitor and an antineoplastic agent. It is functionally related to an umbelliferone.

1. Okanin shows significant activities on both linoleic acid peroxidation inhibition and DPPH radical scavenging effect. 2. Okanin shows significant protective effects against tacrine-induced cytotoxicity in human liver-derived Hep G2 cells with the EC50 value of 29.8±1.1 uM. 3. Okanin can inhibit nitric oxide production and inducible nitric oxide synthase expression via nuclear factor-erythroid 2-related factor 2-dependent heme oxygenase-1 expression in lipopolysaccharide-activated macrophages. 4. Okanin attenuates LPS-induced microglial activation through inhibition of the TLR4/NF-κB signaling pathways, suggests that okanin may have potential as a nutritional preventive strategy for neurodegenerative disorders. Okanin is a member of the class of chalcones that is trans-chalcone substituted by hydroxy groups at positions 3, 4, 2', 3', and 4' respectively. It has a role as a plant metabolite. It is a benzenetriol and a member of chalcones. It is functionally related to a trans-chalcone.
