Lunularin
Based on 1 Customer Validation
Lunularin is an inhibitor of 11β-hydroxysteroid dehydrogenase 1, with an IC50 of 45.44 μM and a Ki of 35.8 μM against human 11β-HSD1, and an IC50 of 17.39 μM and a Ki of 10.31 μM against rat 11β-HSD1. Lunularin upregulates the transcription levels of Sirt1 and Hmox1 genes in the liver. Lunularin reduces food intake and body weight gain, and decreases blood glucose levels in mice fed a high-fat diet. Lunularin inhibits LPS-induced TLR4-mediated NF-κB pathway activation and nitric oxide production. Lunularin inhibits the proliferation and colony formation of renal cancer and colon cancer cells, and exhibits cancer cell-specific cytotoxicity. Lunularin binds to the steroid-binding site of human 11β-HSD1 and the steroid/NADPH-binding region of rat 11β-HSD1, but does not inhibit 11β-HSD2 or mouse 11β-HSD1. Lunularin can be used in research related to diet-induced obesity, renal cancer, colorectal cancer, inflammatory diseases and metabolic syndrome.

Lunularin (20-100 μM; 30 min to standard assay conditions) competitively inhibits human liver microsomal 11β-HSD1 with an IC50 of 45.44 μM and a Ki of 35.8 μM by binding to the enzyme's steroid-binding site[4].
Lunularin (12.5-100 μM; 30 min to standard assay conditions) acts as a mixed inhibitor of rat liver microsomal 11β-HSD1 with an IC50 of 17.39 μM and a Ki of 10.31 μM by binding to the enzyme's combined NADPH and steroid-binding region[4].
Lunularin does not inhibit mouse liver microsomal 11β-HSD1 activity[4].
