Abstract

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. 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. This study demonstrates the strong hepatoprotective activity of MC and MOC, which could be attributed to their potent antioxidant effects.

Abstract

The present work was undertaken to evaluate the ability of F. umbellata aqueous extract and its major component 7-methoxycoumarin (MC) to improve scopolamine-induced spatial memory impairment in ovariectomized Wistar rats. For this to be done, 10 sham-operated and 30 postmenopausal-like rats were randomly distributed in eight groups (n = 5) and treated with distilled water (2 mL/250 g), estradiol valerate (1 mg/kg BW), piracetam (1.5 mg/kg BW), F. umbellata aqueous extract (50 and 200 mg/kg BW), or MC (1 mg/kg BW) for 21 consecutive days. Before and after the memory impairment with scopolamine (2 mg/kg BW), animals underwent behavioral evaluations on Y- and radial mazes. As results, age and ovariectomy did not induce significant changes in the reference memory errors. While age decreased working memory errors, ovariectomy increased it. The MC as well as F. umbellata extract significantly increased (p < 0.01) the percentage of spontaneous alternation and decreased (p < 0.001) working and spatial reference memory errors and anxiety parameters (rearing and grooming) in ovariectomized rats. MC significantly reduced (p < 0.05) the MDA level, but resulted in an increase in GSH level in brain homogenates. These results suggest that MC is endowed with neuroprotective effects and could account for the neuroprotective effects of F. umbellata in rats.

Abstract

In this study, the effects of hydrogen bond (H-bond) formation on fluorescence quenching of 7-methoxycoumarin (7MC) via photo-induced electron transfer from a guanine base (Gua) are investigated using a combined quantum mechanics/molecular mechanics simulation. The electronic structure is calculated by the floating occupation molecular orbital complete active space configuration interaction modification on a semiempirical method. Then the full multiple spawning method is employed for the dynamics simulations on multiple electronic states. The methods employed here are validated by simulating direct dynamics of 7MC (without Gua) and compared with available experimental results. Our computational results are in good agreement with the previously reported experimental results in terms of spectroscopic properties of 7MC. In the case of a H-bonded 7MC-Gua complex, the results from constrained dynamics simulations and single-point calculations suggest that the electron transfer occurs on the second excited state and it depends not only on the H-bond length but also on the intermolecular planarity between 7MC and Gua. Moreover, a proton coupled electron transfer can occur at ≈1 a of H-bond length, where a proton from Gua is also transferred together with the electron to 7MC. The obtained simulations are expected to be greatly beneficial for designing effective fluorescently labeled nucleotide probes as well as providing information for precise fluorescence signal interpretation.
