Galbanic acid, a sesquiterpene coumarin from Ferula szowitsiana, and conferol, another sesquiterpene coumarin from F. badrakema, were evaluated for their effects on the reversal of multi-drug resistance in clinical isolates of Staphylococcus aureus and Escherichia coli, respectively. Neither
In multidrug resistance (MDR), cancer cells exposed to anticancer agents develop resistance to a wide variety of chemicals and chemotherapeutic agents. Sesquiterpene coumarins are reported to inhibit P-glycoprotein and/or increase cytotoxicity of anticancer drugs in P-gp-overexpressing cell lines.
In this study the enhancement effect of Ferula szowitsiana roots' acetone extract on the antibacterial activity of penicillin G and cephalexin was evaluated against Staphylococcus aureus. Disk diffusion and broth dilution methods were used to determine the antibacterial activity of these antibiotics
Galbanic acid, a sesquiterpene coumarin from Ferula szowitsiana roots, was investigated for its potentiating effect on the antimicrobial activity of antibiotics as well as ethidium bromide, in 6 multidrug resistance (MDR) clinical isolates of Staphylococcus aureus. Galbanic acid had inhibitory
OBJECTIVE
Ferula szowitsiana has been widely used for medicinal purposes around the world. The anti-oxidant effect of F. szowitsiana had been proved. The current study aims to determine the protective effects of galbanic acid, a sesquiterpene coumarin from F. szowitsiana, against hydrogen peroxide
Two new sesquiterpene coumarins, named szowitsiacoumarin A (1) and szowitsiacoumarin B (2), and a phenylpropanoid derivative, 2-epihelmanticine (3), together with nine known compounds, auraptene (4), umbelliprenin (5), galbanic acid (6), methyl galbanate (7), farnesiferol B (8), farnesiferol C (9),
Class A and D β-lactamases are the main causes of resistance against β-lactam antibiotics, especially the penam group, in Staphylococcus aureus. On the basis of the potentiator property of ethanolic extracts of Ferula szowitsiana root on penicillin, MIC values observed for resistant S. aureus, the
It is well known that inflammation is associated with various neurodegenerative diseases, such as Parkinson's disease and Alzheimer's disease. An inflammatory mediator, nitric oxide (NO), is produced by inducible NO synthase (iNOS) in microglia and seems to be one of the possible causes of
