Exposure to UV-B Radiation Leads to Increased Deposition of Cell Wall-Associated Xerocomic Acid in Cultures of Serpula himantioides.
Torres S, González-Ramírez M, Gavilán J, Paz C, Palfner G, Arnold N, Fuentealba J, Becerra J, Pérez C, Cabrera-Pardo JR. Torres S, et al. Appl Environ Microbiol. 2019 Aug 29;85(18):e00870-19. doi: 10.1128/AEM.00870-19. Print 2019 Sep 15. Appl Environ Microbiol. 2019. PMID: 31285193 Free PMC article.
We found that increased biosynthesis of xerocomic acid was the main strategy adopted by S. himantioides against UV-B radiation. Xerocomic acid showed strong antioxidant and photoprotective abilities, which has not previously been reported. ...

Pulvinic Acid Derivative Pigments in Lanmaoa asiatica and L. macrocarpa.
Wang Y, Lüli Y, Li X, Yang ZL, Luo H. Wang Y, et al. Chem Biodivers. 2024 May;21(5):e202301996. doi: 10.1002/cbdv.202301996. Epub 2024 Apr 24. Chem Biodivers. 2024. PMID: 38509847
Potential compounds were isolated by HPLC and identified by LC-HRMS and NMR. In total five to six pigments of hydroxylated pulvinic acid derivatives were detected with similar distribution patterns in both L. asiatica and L. macrocarpa, which by abundance were variegatic …

In vitro inhibitory effects of pulvinic acid derivatives isolated from Chinese edible mushrooms, Boletus calopus and Suillus bovinus, on cytochrome P450 activity.
Huang YT, Onose J, Abe N, Yoshikawa K. Huang YT, et al. Biosci Biotechnol Biochem. 2009 Apr 23;73(4):855-60. doi: 10.1271/bbb.80759. Epub 2009 Apr 7. Biosci Biotechnol Biochem. 2009. PMID: 19352038 Free article.
Variegatic acid (2) and xerocomic acid (3) were effective inhibitors, comparable to cimetidine, dicoumarol, erythromycin, safrole, and uniconazole. Variegatic acid (2) and xerocomic acid (3) efficiently reduced ferryl myoglobin in CYPs. . …

Bacteria induce pigment formation in the basidiomycete Serpula lacrymans.
Tauber JP, Schroeckh V, Shelest E, Brakhage AA, Hoffmeister D. Tauber JP, et al. Environ Microbiol. 2016 Dec;18(12):5218-5227. doi: 10.1111/1462-2920.13558. Epub 2016 Oct 24. Environ Microbiol. 2016. PMID: 27699944
Chromophoric natural products derived from the quinone precursor atromentin, such as variegatic acid and involutin, have been shown to function in redox cycling. ...Correspondingly, during co-culturing there was an increase in secreted atromentin-derived pigments, i.e., va …

Dissimilar pigment regulation in Serpula lacrymans and Paxillus involutus during inter-kingdom interactions.
Tauber JP, Gallegos-Monterrosa R, Kovács ÁT, Shelest E, Hoffmeister D. Tauber JP, et al. Microbiology (Reading). 2018 Jan;164(1):65-77. doi: 10.1099/mic.0.000582. Epub 2017 Dec 5. Microbiology (Reading). 2018. PMID: 29205129 Free article.
Production of basidiomycete atromentin-derived pigments like variegatic acid (pulvinic acid-type) and involutin (diarylcyclopentenone) from the brown-rotter Serpula lacrymans and the ectomycorrhiza-forming Paxillus involutus, respectively, is induced by complex nutr …

Simple method for reversed-phase high-performance liquid chromatographic analysis of fungal pigments in fruit-bodies of Boletales (Fungi).
Davoli P, Weber RW. Davoli P, et al. J Chromatogr A. 2002 Jul 26;964(1-2):129-35. doi: 10.1016/s0021-9673(02)00664-7. J Chromatogr A. 2002. PMID: 12198841
A reversed-phase HPLC method has been developed for the analysis of hydroxylated pulvinic acid derivatives which are responsible for the pigmentation of fruit-bodies belonging to the order Boletales (Fungi). Variegatic, xerocomic and atromentic acid as well a …
