Carnosol is an Nrf2 activator, increasing Nrf2 levels and promoting heme oxygenase 1 (HMOX1) expression. It is a ribosomal S6 kinase (RSK2) inhibitor and can be used in gastric cancer-related research with an IC50 value of approximately 5.5 μM.
Rosmanol has antioxidant activity, it can activate the antioxidant response element. Rosmanol has biphasic modulation of GABAA receptors, demonstrates CNS activity in mouse models of antinociception, antidepressant and anxiolysis. Rosmanol potently induce
Methyl rosmarinate is a noncompetitive tyrosinase inhibitor isolated from Rabdosia serra, with an IC50 of 0.28 mM for mushroom tyrosinase. It exhibits antioxidative and antifungal activities, and also inhibits tyrosinase, α±-glucosidase, and matrix metalloproteinase-1 (MMP-1).
7-Methoxyrosmanol (7-O-Methylrosmanol) can effectively suppress FSK-induced luciferase expression under the control of the CRE, PEPCK-C and G6Pase gene promoters, it may contribute to its antihyperglycemic activity.
