BACKGROUND Candida-associated denture stomatitis is a frequent infectious disease. Treatment of this oral condition is difficult because failures and recurrences are common. The aim of this study was to test the in vitro antifungal activity of pure constituents of essentials oils. METHODS Eight terpenic derivatives (carvacrol, farnesol, geraniol, linalool, menthol, menthone, terpinen-4-ol, an...

Essential oils and organic acids are used as feed additives to improve health status and reduce colonization with pathogens. Although bactericidal in vitro, concentrations achieved in the animal gut are probably not lethal to pathogens. The aim of this study was to investigate the effects of cinnamaldehyde, carvacrol and cinnamic, lactic and propionic acids on the ability of Salmonella typhimur...

BACKGROUND The rising drug resistance in pathogenic bacteria and inefficiency of current antibiotics to meet clinical requirements has augmented the need to establish new and innovative approaches for antibacterial drug discovery involving identification of novel antibacterial targets and inhibitors. Being obligatory for bacterial growth, essential gene products are considered vital as drug tar...

In common with other members of the Cys-loop family of pentameric ligand-gated ion channels, 5-hydroxytryptamine type 3 receptors (5-HT3Rs) are activated by the binding of a neurotransmitter to an extracellular orthosteric site, located at the interface of two adjacent receptor subunits. In addition, a variety of compounds have been identified that modulate agonist-evoked responses of 5-HT3Rs, ...

objective: pharmacological effects of carvacrol such as its anti-inflammatory activities have been shows. in this study the effects of carvacrol on serum levels of total protein (tp), phospholipase a2 (pla2) and histamine in sensitized guinea pigs was evaluated. materials and methods: sensitized guinea pigs were given drinking water alone (group s), drinking water containing three concentration...

background and objective: temporal lobe epilepsy (tle) is a chronic neurological disorder with spontaneous recurrent seizures and abnormal intracranial waves. since the role of oxidative stress in the occurrence of epilepsy is inevitable, it seems that the use of antioxidants can prevent some of the complications resulting from this disease. this study was designed to assess the protective effe...

Background: Organophosphorus pesticides has been widely used in agriculture fields to control various crop insects and their extensive use pose human life at threat because of their adverse effects on human health. In this study, we checked the effects of GST polymorphism on ameliorative effect of curcumin and carvacrol against DNA damages. Methods: Comet assay was used to assess the DNA dam...

results the chemical analysis of s. khuzestanica essential oil revealed the presence of carvacrol (94.1%) as its main component. the inhibition zone diameters of s. khuzestanica essential oil and carvacrol dose-dependently increased. the minimum inhibitory concentration (mic) values of s. khuzestanica essential oil and carvacrol were 0.14 ± 0.08 µl/ml and 0.09 ± 0.04 µl/ml, respectively. s. khu...

Thymus species essential oils are widely used in aromatherapy to treat several ailments. However, there is no report on their safety. In this study, we propose to investigate the acute toxicity of T. leptobotrys and T. broussonetii essential oils. These two species were selected on the basis of their frequency of medicinal use and commercial importance. Chemical analysis of these two species es...

background : thymol and carvacrol have previously demonstrated larvicidal activity against aedes aegypti (diptera: culicidae). in view of this fact, it was of our interest to obtain synthetic derivatives and evaluate their larvicidal ac­tivity on ae. aegypti larvae. methods : structural modifications were performed on thymol and carvacrol in an effort to understand the functional groups necessa...
