2(5H)-Furanone sesquiterpenes from Eremophila bignoniiflora: High-resolution inhibition profiling and PTP1B inhibitory activity
Phytochemistry 2019 Oct;166:112054.PMID:31284174DOI:10.1016/j.phytochem.2019.112054.
Eremophila bignoniiflora is a shrub distributed throughout inland northern and eastern Australia, and it has been used in several medicinal applications by some Australian Aboriginal people. In our continued search for anti-diabetic constituents from natural resources, the crude ethyl acetate extract of E. bignoniiflora was found to have protein-tyrosine phosphatase 1B (PTP1B) inhibitory activity with an IC50 value of 23.9 ± 1.9 μg/mL. High-resolution PTP1B inhibition profiling combined with HRMS and NMR were subsequently used to investigate the individual compounds responsible for the observed bioactivity of the crude extract. This led to identification of five undescribed 2(5H)-Furanone sesquiterpenes, together with 13 flavonoids and phenolic compounds. Dose-response curves of the isolated compounds revealed that two 2(5H)-Furanone sesquiterpene cinnamates and three flavonoids exhibited moderate PTP1B inhibitory activity with IC50 values from 41.4 ± 1.4 to 154.5 ± 8.9 μM.
2(5H)-Furanone, epigallocatechin gallate, and a citric-based disinfectant disturb quorum-sensing activity and reduce motility and biofilm formation of Campylobacter jejuni
Folia Microbiol (Praha) 2015 Jan;60(1):89-95.PMID:25231135DOI:10.1007/s12223-014-0344-0.
Brominated furanone and epigallocatechin gallate (EGCG) are naturally occurring polyphenolic compounds that can be derived from sources such as Delisea pulchra algae and green tea, respectively. These compounds may have potential health benefits and antimicrobial properties. Biofilm formation and bacterial motility are virulence factors that seem to be involved in the autoinducer 2 (AI-2)-mediated quorum sensing (QS) response of Campylobacter. In this study, the anti-QS activities of 2(5H)-Furanone, EGCG, and a citric-based disinfectant were tested against Campylobacter jejuni. The minimal bactericidal concentration (MBC) was determined by a microdilution method, and the AI-2 activity was measured by bioluminescence. For motility tests, subinhibitory concentrations of each compound were mixed with semisolid Muller Hinton agar. Biofilm formation was quantified in broth-containing microplates after staining with safranin. The MBC of tested compounds ranged from 0.3 to 310 μg/mL. Subinhibitory concentrations of all of the antimicrobial compounds significantly decreased (19 to 62 %) the bacterial motility and reduced biofilm formation. After treatment with EGCG, furanone, and the disinfectant, AI-2 activity was decreased by 60 to 99 % compared to control. In conclusion, 2(5H)-Furanone, EGCG, and the disinfectant exert bactericidal effects against C. jejuni and disturb QS activity and reduce motility and biofilm formation. These compounds may be naturally occurring alternatives to control C. jejuni.
The Novel Chiral 2(5 H)-Furanone Sulfones Possessing Terpene Moiety: Synthesis and Biological Activity
Molecules 2023 Mar 10;28(6):2543.PMID:36985515DOI:10.3390/molecules28062543.
Over the past decades, 2(5H)-Furanone derivatives have been extensively studied because of their promising ability to prevent the biofilm formation by various pathogenic bacteria. Here, we report the synthesis of a series of optically active sulfur-containing 2(5H)-Furanone derivatives and characterize their biological activity. Novel thioethers were obtained by an interaction of stereochemically pure 5-(l)-menthyloxy- or 5-(l)-bornyloxy-2(5H)-furanones with aromatic thiols under basic conditions. Subsequent thioethers oxidation by an excess of hydrogen peroxide in acetic acid resulted in the formation of the corresponding chiral 2(5H)-Furanone sulfones. The structure of synthesized compounds was confirmed by IR and NMR spectroscopy, HRMS, and single crystal X-ray diffraction. The leading compound, 26, possessing the sulfonyl group and l-borneol moiety, exhibited the prominent activity against Staphylococcus aureus and Bacillus subtilis with MICs of 8 μg/mL. Furthermore, at concentrations of 0.4-0.5 μg/mL, the sulfone 26 increased two-fold the efficacy of aminoglycosides gentamicin and amikacin against S. aureus. The treatment of the model-infected skin wound in the rat with a combination of gentamicin and sulfone 26 speeded up the bacterial decontamination and improved the healing of the wound. The presented results provide valuable new insights into the chemistry of 2(5H)-Furanone derivatives and associated biological activities.
Increasing Susceptibility of Drug-Resistant Candida albicans to Fluconazole and Terbinafine by 2(5 H)-Furanone Derivative
Molecules 2020 Feb 2;25(3):642.PMID:32024254DOI:10.3390/molecules25030642.
The frequency of mycoses caused by drug-resistant fungal pathogen Candida albicans has increased drastically over the last two decades. The spread of drug-resistant strains, along with the limitations of currently available antifungals, complicates the management of fungal infections, thereby representing great challenges for clinical healthcare. Among various antimicrobial pharmacophores, 2(5H)-Furanone derivatives have demonstrated antimicrobial, antifungal, and antibiofilm activities. In this study, we report the antifungal activity of the 2(5H)-Furanone derivative F105, consisting of three pharmacophores, namely chlorinated 2(5H)-Furanone, sulfonyl group, and l-menthol moiety. Although exhibiting moderate antifungal activity alone with the minimum inhibitory concentration (MIC) values of 32-256 μg/mL, F105 potentiates the activity of fluconazole and terbinafine with fractional inhibitory concentration index (FICI) values of 0.27-0.50. Thus, 16 μg/mL of F105 reduced the MICs of these antifungals against fluconazole-resistant C. albicans isolates four-fold, achieving similar values as for the intermediately susceptible phenotype. Confocal laser scanning microscopy revealed that the fluorescent 2(5H)-Furanone derivative F145 was also able to penetrate through biofilms formed by C. albicans. Indeed, in the presence of F105, even sub-MIC concentrations of both fluconazole and terbinafine led to significant reduction of C. albicans CFUs in the mature biofilm. Thus, F105 appears to be a promising candidate for the development of novel antifungal agents as well as enhancers of current antifungal agents, particularly for the treatment of drug-resistant C. albicans infections.
Alpha-pyrones and a 2(5H)-Furanone from Hyptis pectinata
Phytochemistry 2003 Dec;64(7):1303-7.PMID:14599529DOI:10.1016/j.phytochem.2003.08.017.
Three pyrones and a 2(5H)-Furanone, designated pectinolides D-G, have been isolated from the dichloromethane extract of Hyptis pectinata. The metabolites were characterized on the basis of 1D and 2D NMR spectroscopic techniques. The pyrones were identified as 6S-[3S,6S-(diacetoxy)-5R-hydroxy-1Z-heptenyl]-5S-hydroxy-5,6-dihydro-2H-pyran-2-one (1)- pectinolide D, 6S-[3S,5R,6S-(triacetoxy)-1Z-heptenyl]-5S-acetoxy-5,6-dihydro-2H-pyran-2-one (2)- pectinolide E and 6S-[3S,5R,6S-(triacetoxy)-1Z-heptenyl]-5S-acetoxy-4R-methoxy-3,4,5,6-tetrahydro-4H pyran-2-one (3)- pectinolide F. The furanone was identified as [2'Z,5(1')Z] 5-(4'S,6'R,7'S-triacetoxy-2-octenylidene)-2(5H)-furanone (4)-pectinolide G.
