Biological Activity of 7-Methylcoumarin

Description7-Methylcoumarin is an inhibitor for CYP2A6. It has strong hepatoprotective activity, which could be attributed to its potent antioxidant effects.
In vivo

Ameliorative effects of 7-methylcoumarin and 7-methoxycoumarin against CCl4-induced hepatotoxicity in rats.[Pubmed: 23126493 ]

Drug Chem Toxicol. 2013 Jan;36(1):42-7.

The available conventional remedies for the treatment of drug-induced liver diseases are highly inadequate and possess serious adverse effects; therefore, the development of new, effective drugs is considered necessary. This article explores the hepatoprotective and antioxidant potential of 7-Methylcoumarin (MC) and 7-methoxycoumarin (MOC) in CCl(4)-induced hepatotoxicity in rats.
METHODS AND RESULTS:
MC and MOC individually, at doses of 50 and 100 mg/kg body weight, were administered orally once-daily for 7 days. The hepatoprotective activity was assessed using various biochemical parameters, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), serum bilirubin (TB), total protein (TP), and albumin (TA). Serum antioxidant enzyme [e.g., superoxide dismutase (SOD) and catalase (CAT)] levels were determined. Also, thiobarbituric-acid-related substances (TBARS) levels, along with histopathological studies of liver tissue, were scrutinized. Pretreatment with MC and MOC significantly decreased ALT, AST, and TB in the serum of CCl(4)-induced liver damaged rats in a dose-dependent manner. TA and TP levels in the serum were also restored significantly in all presupplemented MC and MOC groups. In addition, oxidative stress induced by CCl(4) was prevented significantly; thereby, increasing SOD and CAT levels and decreasing TBARS levels in liver homogenates. Histopathological studies revealed the ameliorative natures of both the compounds.
CONCLUSIONS:
This study demonstrates the strong hepatoprotective activity of MC and MOC, which could be attributed to their potent antioxidant effects.

Protocol of 7-Methylcoumarin

Kinase Assay

Inhibitory effects and oxidation of 6-methylcoumarin, 7-methylcoumarin and 7-formylcoumarin via human CYP2A6 and its mouse and pig orthologous enzymes.[Pubmed: 26068522 ]

Xenobiotica. 2016;46(1):14-24.

1. Information about the metabolism of compounds is essential in drug discovery and development, risk assessment of chemicals and further development of predictive methods.
METHODS AND RESULTS:
2. In vitro and in silico methods were applied to evaluate the metabolic and inhibitory properties of 6-methylcoumarin, 7-Methylcoumarin and 7-formylcoumarin with human CYP2A6, mouse CYP2A5 and pig CYP2A19. 3. 6-Methylcoumarin was oxidized to fluorescent 7-hydroxy-6-methylcoumarin by CYP2A6 (Km: 0.64-0.91 µM; Vmax: 0.81-0.89 min(-1)) and by CYP2A5 and CYP2A19. The reaction was almost completely inhibited at 10 µM 7-Methylcoumarin in liver microsomes of human and mouse, but in pig only 40% inhibition was obtained with the anti-CYP2A5 antibody or with methoxsalen and pilocarpine. 7-Methylcoumarin was a mechanism-based inhibitor for CYP2A6, but not for the mouse and pig enzymes. 7-Formylcoumarin was a mechanism-based inhibitor for CYP2As of all species. 4. Docking and molecular dynamics simulations of 6-methylcoumarin and 7-Methylcoumarin in the active sites of CYP2A6 and CYP2A5 demonstrated a favorable orientation of the 7-position of 6-methylcoumarin towards the heme moiety. Several orientations of 7-Methylcoumarin were possible in CYP2A6 and CYP2A5.
CONCLUSIONS:
5. These results indicate that the active site of CYP2A6 has unique interaction properties for ligands and differs in this respect from CYP2A5 and CYP2A19.
