Potential of the β-Myrcene Rich Essential Oil from Astronium Urundeuva (M.Allemão) Engl. (Anacardiaceae) to Potentiate Fluconazole Activity and Inhibit Morphological Transition in Candida Species.

Background: In view of the increasing resistance of Candida species, it is necessary to explore alternative strategies. In this context, essential oils have emerged as promising options, among which the essential oil of Astronium urundeuva (M. Allemão) Engl.

Chemical Composition and In Vitro Antibiofilm Action of Varronia curassavica Jacq. (Boraginaceae) Essential Oil: A Promising Natural Agent Against Bacterial Infections.

Antimicrobial resistance is an increasing threat to public health, with alarming estimates of mortality rates. In this context, the clinical properties of Varronia curassavica Jacq. are highlighted due to its biological and pharmacological activities.

ADME/Tox study and the effect of β-Caryophyllene on the resistant strain of carrying the QacA/B efflux pump gene.

The Gram-positive bacterium is responsible for causing both community-acquired and healthcare-associated infections, and it exhibits high antibiotic resistance due to the presence of efflux pumps. These pumps, such as QacA and QacB, are proteins that expel toxic substances, including antibiotics, making infection treatment more difficult. Among the alternatives to combat this resistance are terpenes, like β-caryophyllene, which have the potential to inhibit these efflux pumps due to their nonpolar nature.

Analysis of the Antibiotic-Potentiating Activity, Absorption, Distribution, Metabolism, and Excretion (ADME) and the Molecular Docking Properties of Phytol Against Multi-Drug-Resistant (MDR) Strains.

Phytol is a diterpene from the long-chain unsaturated acyclic alcohols, known for its diverse biological effects, including antimicrobial and anti-inflammatory activities. Present in essential oils, phytol is a promising candidate for various applications in the pharmaceutical and biotechnological sectors. This study aimed to evaluate the antibacterial and drug-potentiating effects of phytol against multidrug-resistant bacteria and to evaluate its properties: ADME and molecular docking.

Eugenia Pohliana Leaves Essential Oil Inhibits Fungal Virulence and Restores Antibiotic Efficacy in Multidrug-Resistant Bacterial Strains.

This study aims to investigate the essential oil from leaves of Eugenia pohliana (EOEP) in regard to its chemical composition, antimicrobial and drug-enhancing activity, as well as the reduction of fungal virulence capacity. Chemical characterization using GC-MS showed as major components the sesquiterpenes δ-cadinene, Epi-α-Muurolol, and bicyclogermacrene. The results of antibacterial tests indicated that Staphylococcus aureus was more sensitive to EOEP, that also enhanced the efficacy of gentamicin, erythromycin, and norfloxacin.

The Genus Ruiz & Pav. (Melastomataceae): Ethnomedicinal Uses, Pharmacology, and Phytochemistry.

Species of the genus are used in traditional medicine for the treatment of diseases, such as pain, throat infections, fever, and cold, and they used as depuratives, diuretics, and sedatives. This work reviewed studies carried out with species, highlighting its ethnomedicinal uses and pharmacological and phytochemical potential. This information was collected in the main platforms of scientific research (PubMed, Scopus, and Web of Science).
