4′,6-Dihydroxy-4-methoxyisoaurone inhibits TNF-α-induced NF-κB activation and expressions of NF-κB-regulated target gene products

Journal of Pharmacological Sciences, 2016
The nuclear factor-κB (NF-κB) transcription factors control many physiological processes including inflammation, apoptosis, and angiogenesis. In our search for NF-κB inhibitors from natural resources, we identified 4′,6-dihydroxy-4-methoxyisoaurone (ISOA)

Isoprene Production by Sphagnum Moss Is Balanced by Microbial Uptake, as Revealed by Selective Inhibitors [PDF]

Environmental Microbiology, Volume 27, Issue 6, June 2025.
Sphagnum moss, typical of northern peatlands, produces a range of volatile organic compounds, principally the climate‐active compound, isoprene, which serves as a carbon source for specialist isoprene‐consuming microbes. Using an inhibitor of microbial isoprene uptake, we quantify gross isoprene production by the moss and show that the vast majority of

Gene probing reveals the widespread distribution, diversity and abundance of isoprene-degrading bacteria in the environment [PDF]

Microbiome, 2018
Background Approximately 500 Tg of isoprene are emitted to the atmosphere annually, an amount similar to that of methane, and despite its significant effects on the climate, very little is known about the biological degradation of isoprene in the ...

Isolation of isoprene degrading bacteria from soils, development of isoA gene probes and identification of the active isoprene‐degrading soil community using DNA‐stable isotope probing [PDF]

Environmental Microbiology, 2016
Summary Emissions of biogenic volatile organic compounds (bVOCs), are an important element in the global carbon cycle, accounting for a significant proportion of fixed carbon. They contribute directly and indirectly to global warming and climate change and have a major effect on atmospheric chemistry.
