<p>3-Cyano-7-hydroxycoumarin (3-Cyanoumbelliferone) is a macrophage inhibitor of macrophage inhibitory factor (MIF) interconjugate isomerase with a Ki of 2.9 μM.</p>

<p>(+)-6-(2-Hydroxy-3-methoxy-3-methylbutyl is a structural isomer of Ent-toddalolactone, which belongs to the coumarin group.</p>

<p>3-Aminocoumarin (3-aminochromen-2-one) is the key intermediate for the metal complexes.</p>

<p>7-BFC (7-Benzyloxy-4-(trifluoromethyl)coumarin) is a coumarin-like fluorescent substrate that is a cytochrome marker for the study of CYP subtypes.</p>

<p>7-Hydroxycoumarin-3-carboxylic acid (7-HC-3-CA) is a safe anti-browning agent that inhibits tyrosinase activity, useful for studying food preservation.</p>

<p>7-Methoxycoumarin-3-carboxylic acid is used for HPLC derivatization. It is also used to develop FRET probes for analyzing protease activities.</p>

Oxypeucedanin hydrate is an antimutagenic agent, it has antioxidant activity, and exhibits carbohydrate metabolizing enzymes inhibitory effect.

<p>M02744 - 4-Methylumbelliferyl-a-D-galactopyranoside</p>

Oxypeucedanin is a major coumarin aglycone that can be extracted from Ostericum koreanum, coumarin aglycones have demonstrated various pharmacological effects, including anti-proliferation, anti-inflammation, and anti-pain; based on transcriptional alteration and complicated modulation of MAPK signaling, might be underlying mechanisms responsible for the various pharmacological effects of oxypeucedanin.

Umbelliferone (UMB), a natural antioxidant, is benzopyrone in nature, and it is present in the fruits of golden apple and bitter orange, UMB has a protective effect on membrane fatty acid composition of liver and kidney as supported by antioxidant and antihyperlipidemic effects of UMB reported earlier as evidenced by improved histopathological changes, hepatic and nephritic markers, indicating recovery from the risk of diabetic complications; UMB has antihyperglycemic effect, UMB at 30 mg/kg of body weight possesses a promising antihyperglycemic effect that is comparable with glibenclamide.[1,2]

Scopoletin exhibits antifungal, anti-allergic, anti-aging, and hypouricemic activities, it exerts anti-RA action probably through suppressing IL-6 production from fibroblast-like synoviocytes via MAPK/PKC/CREB pathways. Scopoletin can ameliorate alcohol-induced hepatic lipid accumulation by modulating AMPK-SREBP pathway-mediated lipogenesis in mice fed a high-fat diet.

Isoimperatorin is a medicinal herbal product that is isolated from the dried roots of Angelicae dahuricae ,can inhibit the cyclooxygenase-2 (COX-2) and COX-1-dependent phases of prostaglandin D 2 (PGD 2 ) generation in bone marrow-derived mast cells (BMMC) in a concentration-dependent manner, with IC 50 values of 10.7 μM and 24 μM, respectively; it may provide the basis for novel anti-inflammatory drugs.
