1. Halomethoxybenzenes in air of the Nordic region
Terry Bidleman, Agneta Andersson, Eva Brorström-Lundén, Sonia Brugel, Lars Ericson, Katarina Hansson, Mats Tysklind Environ Sci Ecotechnol. 2022 Nov 11;13:100209. doi: 10.1016/j.ese.2022.100209. eCollection 2023 Jan.
Halomethoxybenzenes (HMBs) are a group of compounds with natural and anthropogenic origins. Here we extend a 2002-2015 survey of bromoanisoles (BAs) in the air and precipitation at Råö on the Swedish west coast and Pallas in Subarctic Finland. New BAs data are reported for 2018 and 2019 and chlorinated HMBs are included for these and some previous years: drosophilin A methyl ether (DAME: 1,2,4,5-tetrachloro-3,6-dimethoxybenzene), tetrachloroveratrole (TeCV: 1,2,3,4-tetrachloro-5,6-dimethoxybenzene), and pentachloroanisole (PeCA). The order of abundance of HMBs at Råö was ΣBAs > DAME > TeCV > PeCA, whereas at Pallas the order of abundance was DAME > ΣBAs > TeCA > PeCA. The lower abundance of BAs at Pallas reflects its inland location, away from direct marine influence. Clausius-Clapeyron (CC) plots of log partial pressure (Pair)/Pa versus 1/T suggested distant transport at both sites for PeCA and local exchange for DAME and TeCV. BAs were dominated by distant transport at Pallas and by both local and distant sources at Råö. Relationships between air and precipitation concentrations were examined by scavenging ratios, SR = (ng m-3)precip/(ng m-3)air. SRs were higher at Pallas than Råö due to greater Henry's law partitioning of gaseous compounds into precipitation at colder temperatures. DAME is produced by terrestrial fungi. We screened 19 fungal species from Swedish forests and found seven of them contained 0.01-3.8 mg DAME per kg fresh weight. We suggest that the volatilization of DAME from fungi and forest litter containing fungal mycelia may contribute to atmospheric levels at both sites.
2. Substantial production of drosophilin A methyl ether (tetrachloro-1,4-dimethoxybenzene) by the lignicolous basidiomycete Phellinus badius in the heartwood of mesquite (Prosopis juliflora) trees
Laurence A J Garvie, Barry Wilkens, Thomas L Groy, Jessie A Glaeser Naturwissenschaften. 2015 Apr;102(3-4):18. doi: 10.1007/s00114-015-1268-5. Epub 2015 Apr 2.
Toxic organohalogen pollutants produced as by-products of industrial processes, such as chloroform and polychlorinated dibenzo-p-dioxins, also have significant natural sources. A substantial terrestrial source of halogenated organics originates from fungal decay of wood and leaf litter. Here we show that the lignicolous basidiomycete Phellinus badius deposits up to 30,000 mg of the halogenated metabolite drosophilin A methyl ether (DAME, tetrachloro-1,4-dimethoxybenzene) per kilogram of decayed heartwood in the mesquite Prosopis juliflora. DAME occurs as clusters of glassy crystals up to 1 mm long within the decayed heartwood. In addition, the Phellinus badius basidiocarps contain an average of 24,000 mg DAME/kg dried fruiting body, testifying to the significant translocation and accumulation of Cl accompanied by DAME biosynthesis. The high DAME concentrations attest to the substantial Cl content of the heartwood, which averages near 5,000 ppm, with Cl/K near 1:1, consistent with an inorganic chloride precursor. Phellinus badius has a circumglobal distribution in the tropics and subtropics, where it is widely distributed on hardwoods and commonly associated with decay of mesquite. There is the potential for extensive DAME formation within decayed heartwood worldwide given the extensive range of Phellinus badius and its propensity to form DAME within mesquites. Further, DAME production is not limited to Phellinus badius but occurs in a range of lignicolous basidiomycetes, suggesting a significant natural reservoir for this chloroaromatic with potential environmental implications.
3. Polychlorinated compounds with PPAR-gamma agonistic effect from the medicinal fungus Phellinus ribis
In-Kyoung Lee, Jeong-Hyung Lee, Bong-Sik Yun Bioorg Med Chem Lett. 2008 Aug 15;18(16):4566-8. doi: 10.1016/j.bmcl.2008.07.034. Epub 2008 Jul 15.
During the search for natural substances with PPAR-gamma agonistic effect, unique polychlorinated compounds named chlorophellins A-C have been isolated together with the known compound, drosophilin A, from the methanolic extract of the fruiting body of the fungus Phellinus ribis. Their structures were assigned on the basis of NMR and mass spectrometric analyses. Chlorophellin C of compounds tested exhibited the most potent PPAR-gamma agonistic effect and was comparable to rosiglitazone, a well-known PPAR-gamma agonist that has been used for the therapy of type 2 diabetes.
